EN-Product-Cold-rolled-HSS-All Grades OverviewTSUK

Overview

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-All Grades Surface aspectsTSUK

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%.

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.
