Overview

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

Produced in the Netherlands.  For further information click here.

Carbon manganese grades

Our carbon manganese product combines high strength with excellent formability for the most difficult cold forming applications.

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 with ‘Regular matte’ surface texture.

DescriptionRoughness µinch CLA
Regular matte24 - 76

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, 37-241 mg/ft2 per side.  Please specify your exact requirements in the enquiry.
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.
Continuously annealed products typically exhibit a loss of reflection up to around 10%.

Overview

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

Produced in the Netherlands.  For further information click here.

Carbon manganese grades

Our carbon manganese product combines high strength with excellent formability for the most difficult cold forming applications.

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 with ‘Regular matte’ surface texture.

DescriptionRoughness µinch CLA
Regular matte24 - 76

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, 37-241 mg/ft2 per side.  Please specify your exact requirements in the enquiry.
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.
Continuously annealed products typically exhibit a loss of reflection up to around 10%.

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 with ‘Regular matte’ surface texture.

DescriptionRoughness µinch CLA
Regular matte24 - 76

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, 37-241 mg/ft2 per side.  Please specify your exact requirements in the enquiry.
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.
Continuously annealed products typically exhibit a loss of reflection up to around 10%.

Tolerances on thickness

Tata Steel can supply to full thickness tolerance specified in ASTM A568: 2015.
Thickness tolerances over, no tolerance under. Tighter tolerances are available as shown below:

Minimum thickness, 0.021 in. for high-strength, low-alloy.
The specified thickness range captions apply independent of whether the ordered thickness is stated as a nominal or minimum.
The tolerances provided in the table are based on minimum thickness (tolerance over, no tolerance under).
For nominal thickness, the tolerance is divided equally over and under.

Tolerances on width, edge camber and flatness

Material will be supplied conforming to the tolerances specified in ASTM A568 (2007) / A635 (2007).
Width tolerances are over, no tolerance under.
