Cold-rolled
Steel for forming

Cold-rolled steel for cold forming and deep drawing is available in a range of grades.  Each grade is designed for particular applications – allowing you to pick the best steel for your product.

Our forming steel is available in a choice of widths up to 2050 mm and thicknesses up to 3 mm. This provides opportunities for cutting waste and maximising yield. These products are made using one of two process routes:

  • continuous annealing (CA)
  • batch annealing (BA)

    Surface aspects

    Surface quality

     

    Surface quality A

    Defects that do not influence the formability or the application of surface coatings are permitted. They are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration. 

    Surface quality B

    The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality A. Not all combinations of thickness and width are available in surface quality B. Please contact us for details. 

    Inspected side

    As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.

     

    Surface texture/roughness

    Cold-rolled annealed and skin-passed steel is available in several surface textures. Unless specified otherwise, Tata Steel will supply normal roughness. The table below shows the range of surface textures according to EN 10130:2006.

    Other surface textures are available to meet your requirements - please contact us for details

     

    Preservative oil

    The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.
    Tata Steel offers a range of oiling levels from 0.25 - 1.7 g/m2 per side.
    Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the un-oiled condition.

     

    Surface cleanliness

    Tata Steel can guarantee improved surface cleanliness on request for batch-annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product. Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%. Continuously-annealed products typically exhibit a loss of reflection up to around 10%.

    Mechanical properties

    Cold-rolled steel for forming has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:

    EN 10130: 2006 Grade DC01
    Max. yield strength Re 1,2,6 N/mm2 280
    Tensile strength Rm N/mm 270 - 410
    Elongation 3 % 28
    r90-value 4,5   -
    n90-value 4   -
    1. The values of the yield strength are those of the 0.2% yield strength for products with no definite yield point and the lower yield strength ReL for the other products.
    2. For thicknesses > 0.5 mm and ≤ 0.7 mm, the value for yield strength is increased by 20 N/mm2.
       For thicknesses ≤ 0.5 mm, the value is increased by 40 N/mm2.
    3. For thicknesses > 0.5 mm and ≤ 0.7 mm the minimum elongation after fracture is decreased by 2%. For thicknesses ≤ 0.5 mm the minimum elongation after fracture is decreased by 4%.
       Elongation after fracture A uses test piece length L0 =  80 mm.
    4. The r- and n- values apply to a thickness of t ≥ 0.5 mm.
    5. For a thickness of t > 2 mm, the r90 value or r-average value is decreased by 0.2.
    6. For design purposes, a lower yield strength ReL of at least 140 N/mm2 can be assumed.

    Coil welds

    For batch-annealed coils, in general, pickling line welds are included. The number of permissible recoiling line welds is determined in consultation with the customer. If welds are permitted, Tata Steel is better able to implement the best coil weight. A recoiling line weld is marked with a single hole in the centre of the strip, close to the weld. On request the identifying hole can be left out. Coils with welds are available on continuously-annealed products – please contact us for details. You can find details on how to get in touch with us in 'Contact Us' below.

    Surface aspects

    Surface quality

     

    Surface quality A

    Defects that do not influence the formability or the application of surface coatings are permitted. They are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration. 

    Surface quality B

    The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality A. Not all combinations of thickness and width are available in surface quality B. Please contact us for details. 

    Inspected side

    As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.

     

    Surface texture/roughness

    Cold-rolled annealed and skin-passed steel is available in several surface textures. Unless specified otherwise, Tata Steel will supply normal roughness. The table below shows the range of surface textures according to EN 10130:2006.

    Other surface textures are available to meet your requirements - please contact us for details

     

    Preservative oil

    The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.
    Tata Steel offers a range of oiling levels from 0.25 - 1.7 g/m2 per side.
    Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the un-oiled condition.

     

    Surface cleanliness

    Tata Steel can guarantee improved surface cleanliness on request for batch-annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product. Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%. Continuously-annealed products typically exhibit a loss of reflection up to around 10%.

    Properties


    Mechanical properties

    Cold-rolled steel for forming has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:

    EN 10130: 2006 Grade DC03
    Max. yield strength Re 1,2,6 N/mm2 240
    Tensile strength Rm N/mm 270 - 370
    Elongation 3 % 34
    r90-value 4,5   1.3
    n90-value 4   -
    1. The values of the yield strength are those of the 0.2% yield strength for products with no definite yield point and the lower yield strength ReL for the other products.
    2. For thicknesses > 0.5 mm and ≤ 0.7 mm, the value for yield strength is increased by 20 N/mm2.
       For thicknesses ≤ 0.5 mm, the value is increased by 40 N/mm2.
    3. For thicknesses > 0.5 mm and ≤ 0.7 mm the minimum elongation after fracture is decreased by 2%. For thicknesses ≤ 0.5 mm the minimum elongation after fracture is decreased by 4%.
       Elongation after fracture A uses test piece length L0 =  80 mm.
    4. The r- and n- values apply to a thickness of t ≥ 0.5 mm.
    5. For a thickness of t > 2 mm, the r90 value or r-average value is decreased by 0.2.
    6. For design purposes, a lower yield strength ReL of at least 140 N/mm2 can be assumed.

    Chemical composition

    Coil welds

    For batch-annealed coils, in general, pickling line welds are included. The number of permissible recoiling line welds is determined in consultation with the customer. If welds are permitted, Tata Steel is better able to implement the best coil weight. A recoiling line weld is marked with a single hole in the centre of the strip, close to the weld. On request the identifying hole can be left out. Coils with welds are available on continuously-annealed products – please contact us for details. You can find details on how to get in touch with us in 'Contact Us' below.

    Surface aspects

    Surface quality

     

    Surface quality A

    Defects that do not influence the formability or the application of surface coatings are permitted. They are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration. 

    Surface quality B

    The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality A. Not all combinations of thickness and width are available in surface quality B. Please contact us for details. 

    Inspected side

    As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.

     

    Surface texture/roughness

    Cold-rolled annealed and skin-passed steel is available in several surface textures. Unless specified otherwise, Tata Steel will supply normal roughness. The table below shows the range of surface textures according to EN 10130:2006.

    Other surface textures are available to meet your requirements - please contact us for details

     

    Preservative oil

    The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.
    Tata Steel offers a range of oiling levels from 0.25 - 1.7 g/m2 per side.
    Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the un-oiled condition.

     

    Surface cleanliness

    Tata Steel can guarantee improved surface cleanliness on request for batch-annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product. Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%. Continuously-annealed products typically exhibit a loss of reflection up to around 10%.

    Properties

    Properties


    Mechanical properties

    Cold-rolled steel for forming has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:

    EN 10130: 2006 Grade DC04
    Max. yield strength Re 1,2,6 N/mm2 210
    Tensile strength Rm N/mm 270 - 350
    Elongation 3 % 38
    r90-value 4,5   1.6
    n90-value 4   0.180
    1. The values of the yield strength are those of the 0.2% yield strength for products with no definite yield point and the lower yield strength ReL for the other products.
    2. For thicknesses > 0.5 mm and ≤ 0.7 mm, the value for yield strength is increased by 20 N/mm2.
       For thicknesses ≤ 0.5 mm, the value is increased by 40 N/mm2.
    3. For thicknesses > 0.5 mm and ≤ 0.7 mm the minimum elongation after fracture is decreased by 2%. For thicknesses ≤ 0.5 mm the minimum elongation after fracture is decreased by 4%.
       Elongation after fracture A uses test piece length L0 =  80 mm.
    4. The r- and n- values apply to a thickness of t ≥ 0.5 mm.
    5. For a thickness of t > 2 mm, the r90 value or r-average value is decreased by 0.2.
    6. For design purposes, a lower yield strength ReL of at least 140 N/mm2 can be assumed.

    Coil welds

    For batch-annealed coils, in general, pickling line welds are included. The number of permissible recoiling line welds is determined in consultation with the customer. If welds are permitted, Tata Steel is better able to implement the best coil weight. A recoiling line weld is marked with a single hole in the centre of the strip, close to the weld. On request the identifying hole can be left out. Coils with welds are available on continuously-annealed products – please contact us for details. You can find details on how to get in touch with us in 'Contact Us' below.

    Surface aspects

    Surface quality

     

    Surface quality A

    Defects that do not influence the formability or the application of surface coatings are permitted. They are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration. 

    Surface quality B

    The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality A. Not all combinations of thickness and width are available in surface quality B. Please contact us for details. 

    Inspected side

    As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.

     

    Surface texture/roughness

    Cold-rolled annealed and skin-passed steel is available in several surface textures. Unless specified otherwise, Tata Steel will supply normal roughness. The table below shows the range of surface textures according to EN 10130:2006.

    Other surface textures are available to meet your requirements - please contact us for details

     

    Preservative oil

    The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.
    Tata Steel offers a range of oiling levels from 0.25 - 1.7 g/m2 per side.
    Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the un-oiled condition.

     

    Surface cleanliness

    Tata Steel can guarantee improved surface cleanliness on request for batch-annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product. Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%. Continuously-annealed products typically exhibit a loss of reflection up to around 10%.

    Properties

    Properties


    Mechanical properties

    Cold-rolled steel for forming has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:

    EN 10130: 2006 Grade DC05
    Max. yield strength Re 1,2,6 N/mm2 180
    Tensile strength Rm N/mm 270 - 330
    Elongation 3 % 40
    r90-value 4,5   1.9
    n90-value 4   0.200
    1. The values of the yield strength are those of the 0.2% yield strength for products with no definite yield point and the lower yield strength ReL for the other products.
    2. For thicknesses > 0.5 mm and ≤ 0.7 mm, the value for yield strength is increased by 20 N/mm2.
       For thicknesses ≤ 0.5 mm, the value is increased by 40 N/mm2.
    3. For thicknesses > 0.5 mm and ≤ 0.7 mm the minimum elongation after fracture is decreased by 2%. For thicknesses ≤ 0.5 mm the minimum elongation after fracture is decreased by 4%.
       Elongation after fracture A uses test piece length L0 =  80 mm.
    4. The r- and n- values apply to a thickness of t ≥ 0.5 mm.
    5. For a thickness of t > 2 mm, the r90 value or r-average value is decreased by 0.2.
    6. For design purposes, a lower yield strength ReL of at least 140 N/mm2 can be assumed.

    Coil welds

    For batch-annealed coils, in general, pickling line welds are included. The number of permissible recoiling line welds is determined in consultation with the customer. If welds are permitted, Tata Steel is better able to implement the best coil weight. A recoiling line weld is marked with a single hole in the centre of the strip, close to the weld. On request the identifying hole can be left out. Coils with welds are available on continuously-annealed products – please contact us for details. You can find details on how to get in touch with us in 'Contact Us' below.

    Surface aspects

    Surface quality

     

    Surface quality A

    Defects that do not influence the formability or the application of surface coatings are permitted. They are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration. 

    Surface quality B

    The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality A. Not all combinations of thickness and width are available in surface quality B. Please contact us for details. 

    Inspected side

    As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.

     

    Surface texture/roughness

    Cold-rolled annealed and skin-passed steel is available in several surface textures. Unless specified otherwise, Tata Steel will supply normal roughness. The table below shows the range of surface textures according to EN 10130:2006.

    Other surface textures are available to meet your requirements - please contact us for details

     

    Preservative oil

    The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.
    Tata Steel offers a range of oiling levels from 0.25 - 1.7 g/m2 per side.
    Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the un-oiled condition.

     

    Surface cleanliness

    Tata Steel can guarantee improved surface cleanliness on request for batch-annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product. Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%. Continuously-annealed products typically exhibit a loss of reflection up to around 10%.

    Properties

    Properties


    Mechanical properties

    Cold-rolled steel for forming has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:

    EN 10130: 2006 Grade DC06
    Max. yield strength Re 1,2,6 N/mm2 170
    Tensile strength Rm N/mm 270 - 330
    Elongation 3 % 41
    r90-value 4,5   2.1
    n90-value 4   0.220
    1. The values of the yield strength are those of the 0.2% yield strength for products with no definite yield point and the lower yield strength ReL for the other products.
    2. For thicknesses > 0.5 mm and ≤ 0.7 mm, the value for yield strength is increased by 20 N/mm2.
       For thicknesses ≤ 0.5 mm, the value is increased by 40 N/mm2.
    3. For thicknesses > 0.5 mm and ≤ 0.7 mm the minimum elongation after fracture is decreased by 2%. For thicknesses ≤ 0.5 mm the minimum elongation after fracture is decreased by 4%.
       Elongation after fracture A uses test piece length L0 =  80 mm.
    4. The r- and n- values apply to a thickness of t ≥ 0.5 mm.
    5. For a thickness of t > 2 mm, the r90 value or r-average value is decreased by 0.2.
    6. For design purposes, a lower yield strength ReL of at least 120 N/mm2 can be assumed.

    Out-of-squareness (products supplied as cut sheets only)

    The deviation does not exceed 1% of the actual width of the sheet according to the EN 10131: 2006 standard. The deviation from the edge camber does not exceed 5mm for a length of 2 metres as specified in EN 10131: 2006.

     

    Flatness (products supplied as skin-passed cut sheets only)

    Flatness complies with EN 10131: 2006
    If there is a dispute about the flatness of material that was ordered to the special tolerances shown in table 8 of EN 10131: 2006, then the minimum acceptable standards of flatness described below must be verified.

    Coil welds

    For batch-annealed coils, in general, pickling line welds are included. The number of permissible recoiling line welds is determined in consultation with the customer. If welds are permitted, Tata Steel is better able to implement the best coil weight. A recoiling line weld is marked with a single hole in the centre of the strip, close to the weld. On request the identifying hole can be left out. Coils with welds are available on continuously-annealed products – please contact us for details. You can find details on how to get in touch with us in 'Contact Us' below.
