Overview

Our forming steel is available in a choice of widths up to 72 inch and thicknesses up to 0.12 inch. This provides opportunities for cutting waste and maximising yield.These products are made using one of two process routes:

continuous annealing (CA) up to 0.06 inch
batch annealing (BA) up to 0.12 inch

Applications

Automotive components and body panels
Building components
Domestic appliances
Electrical goods
Furniture
Radiators
Tubes
Drums
Coins

Relationship with standards

Cold-rolled steel for forming complies with ASTM A1008: 2013 and is available in the grades shown below.

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

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.

Description	Roughness µinch CLA
Regular matte	24 - 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%.

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.

Overview

Our forming steel is available in a choice of widths up to 72 inch and thicknesses up to 0.12 inch. This provides opportunities for cutting waste and maximising yield.These products are made using one of two process routes:

continuous annealing (CA) up to 0.06 inch
batch annealing (BA) up to 0.12 inch

Applications

Automotive components and body panels
Building components
Domestic appliances
Electrical goods
Furniture
Radiators
Tubes
Drums
Coins

Relationship with standards

Cold-rolled steel for forming complies with ASTM A1008: 2013 and is available in the grades shown below.

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

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.

Description	Roughness µinch CLA
Regular matte	24 - 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%.
