Overview

Grades

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. There is limited scope for cold forming.

Tata Steel supplies high-strength micro-alloyed (HSLA) steel which complies with European standard EN 10268:2006+A1:2013.

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.

Rephosphorised grades

These grades deliver high mechanical resistance and good suitability for cold forming due to solid solution hardening by phosphorus. Our rephosphorised 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.

RADECOL grades                                                                             

Tailor-made for steel panel radiators offering higher strength and improved shape consistency. Manufacturers can down-gauge to improve their yield and produce lightweight radiators for ease of installation.
