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)

Applications

  • Automotive components and body panels
  • Components for building
  • Domestic appliances
  • Electrical goods
  • Furniture
  • Radiators
  • Tubes

Overview

Overview

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 81 inches and thicknesses up to 0.122 inch. 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 aspects

Surface quality according to ASTM A1008: 2013 and ASTM A568: 2011
 

Surface quality class 1 (exposed):

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 unexposed.
 

Surface quality class 2 (unexposed):

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

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. All textures are available.
Unless specified otherwise, Tata Steel will supply ‘Regular matte’.
 

Description Roughness µinch CLA
Commercial bright ≤ 10
H - dull ≤ 16
Light matte ≤ 36
Regular matte 24 - 76
Rough matte 64 - 100

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:
Lightly oiled:  55 mg/ft2 per side
Regular oiled:  110 mg/ft2 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 unoiled 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%.

EN_US-Engineering-Product-Cold-rolled-Forming-All Grades Overview

Overview

Overview

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 81 inches and thicknesses up to 0.122 inch. 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)
     

Applications

  • Automotive components and body panels
  • Components for building
  • Domestic appliances
  • Electrical goods
  • Furniture
  • Radiators
  • Tubes
     

EN_US-Engineering-Product-Cold-rolled-All Grades Surface aspects

Surface aspects

Surface aspects

Surface quality according to ASTM A1008: 2013 and ASTM A568: 2011
 

Surface quality class 1 (exposed):

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 unexposed.
 

Surface quality class 2 (unexposed):

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

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. All textures are available.
Unless specified otherwise, Tata Steel will supply ‘Regular matte’.
 

Description Roughness µinch CLA
Commercial bright ≤ 10
H - dull ≤ 16
Light matte ≤ 36
Regular matte 24 - 76
Rough matte 64 - 100

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:
Lightly oiled:  55 mg/ft2 per side
Regular oiled:  110 mg/ft2 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 unoiled 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%.
