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.

Properties
Mechanical properties
The available grades have the following mechanical properties - these are measured perpendicular to the rolling direction (transverse test pieces):
RADECOL grades
| Tata Steel | Grade | RADECOL 0 |
|---|---|---|
| Yield strength Rp0,21 | N/mm2 | 200 - 290 |
| Tensile strength Rm | N/mm2 | 310 - 390 |
| Elongation | % | 30 |
1. If the yield strength is pronounced (yield flag), the values apply to the lower yield point (ReL).
Chemical composition
Cold-rolled high-strength steels supplied by Tata Steel comply to the following cast analysis with maximum values unless otherwise shown:
| Grade | RADECOL 0 | |
|---|---|---|
| C | Max. | 0.085 |
| Mn | Max. | 0.55 |
| Si | Max. | 0 |
| P | Max. | 0.03 |
| S | Max. | 0.03 |
| Alsol | Min. | 0.015 |
All values are in weight%.
