Overview
These steels are ideal for manufacturing strong, thin-gauge products. Our high-strength steels are a popular choice in the automotive industry where they deliver benefits including dent resistance, crash resistance, formability and good weldability.
Microalloyed grades
Microalloyed grades have high-strength levels through precipitation and grain refinement hardening. Careful use of alloying elements ensures high mechanical resistance and good weldability. There is limited scope for cold forming. Tata Steel supplies high-strength microalloyed (HSLA) steel which complies with ASTM standard A1008: 2013.
Rephosphorized grades
These grades deliver high mechanical resistance and good suitability for cold forming due to solid solution hardening by phosphorus. Our rephosphorized grades are highly suited to the manufacture of car body panels and structural components because of their good resistance to impact and fatigue.
Carbon manganese grades
Our carbon manganese product combines high strength with excellent formability for the most difficult cold forming applications.
Applications
- Automotive parts
- Construction parts
- Furniture
- Precision tubes

EN_US-Engineering-Product-Cold-rolled-All Grades Surface aspectsTSE
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 | 50 - 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-HSS-All Grades OverviewTSE
Overview
These steels are ideal for manufacturing strong, thin-gauge products. Our high-strength steels are a popular choice in the automotive industry where they deliver benefits including dent resistance, crash resistance, formability and good weldability.
Microalloyed grades
Microalloyed grades have high-strength levels through precipitation and grain refinement hardening. Careful use of alloying elements ensures high mechanical resistance and good weldability. There is limited scope for cold forming. Tata Steel supplies high-strength microalloyed (HSLA) steel which complies with ASTM standard A1008: 2013.
Rephosphorized grades
These grades deliver high mechanical resistance and good suitability for cold forming due to solid solution hardening by phosphorus. Our rephosphorized grades are highly suited to the manufacture of car body panels and structural components because of their good resistance to impact and fatigue.
Carbon manganese grades
Our carbon manganese product combines high strength with excellent formability for the most difficult cold forming applications.
Applications
- Automotive parts
- Construction parts
- Furniture
- Precision tubes

EN_US-Engineering-Product-Cold-rolled-All Grades Surface aspectsTSE
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 | 50 - 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-HSS-All Grades OverviewTSE
Overview
These steels are ideal for manufacturing strong, thin-gauge products. Our high-strength steels are a popular choice in the automotive industry where they deliver benefits including dent resistance, crash resistance, formability and good weldability.
Microalloyed grades
Microalloyed grades have high-strength levels through precipitation and grain refinement hardening. Careful use of alloying elements ensures high mechanical resistance and good weldability. There is limited scope for cold forming. Tata Steel supplies high-strength microalloyed (HSLA) steel which complies with ASTM standard A1008: 2013.
Rephosphorized grades
These grades deliver high mechanical resistance and good suitability for cold forming due to solid solution hardening by phosphorus. Our rephosphorized grades are highly suited to the manufacture of car body panels and structural components because of their good resistance to impact and fatigue.
Carbon manganese grades
Our carbon manganese product combines high strength with excellent formability for the most difficult cold forming applications.
Applications
- Automotive parts
- Construction parts
- Furniture
- Precision tubes

EN_US-Engineering-Product-Cold-rolled-All Grades Surface aspectsTSE
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 | 50 - 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%.

Micro-alloyed grades
Micro-alloyed grades have high-strength levels through precipitation and grain refinement hardening. Careful use of alloying elements ensures high mechanical resistance and good weldability. Micro alloyed grades are suited to pressed or stamped parts that require high strength and good formability eg. in seating or body in white structural parts.
Tata Steel supplies high-strength micro-alloyed (HSLA) steel which complies with European standard EN 10268:2006+A1:2013 and to VDA 239-100.
Bake-hardening grades
Bake hardening steel gains extra strength after going through an automotive paint oven. The benefit of this is a product with relatively good formability, combined with a higher strength final part.
Carbon manganese grades
Our carbon manganese product combines high strength with excellent formability for the most difficult cold forming applications.

EN-Product-Cold-rolled-HSS-All Grades OverviewTSUK
Micro-alloyed grades
Micro-alloyed grades have high-strength levels through precipitation and grain refinement hardening. Careful use of alloying elements ensures high mechanical resistance and good weldability. Micro alloyed grades are suited to pressed or stamped parts that require high strength and good formability eg. in seating or body in white structural parts.
Tata Steel supplies high-strength micro-alloyed (HSLA) steel which complies with European standard EN 10268:2006+A1:2013 and to VDA 239-100.
Bake-hardening grades
Bake hardening steel gains extra strength after going through an automotive paint oven. The benefit of this is a product with relatively good formability, combined with a higher strength final part.
Carbon manganese grades
Our carbon manganese product combines high strength with excellent formability for the most difficult cold forming applications.
Rephosphorised grades
Produced in the Netherlands. For further information click here.
Applications
Automotive components.
