1. SCOPE
The materials defined by these Global specifications are fully killed, fine grained, high strength steel
sheet with specified minimum yield strength between 180 MPa and 700 MPa, suitable for cold forming
such as stamping, roll forming and tube making, and use in automotive applications.
The specification applies to uncoated and coated steel sheet generally categorized as high strength
steels:
- Cold Rolled, Solution Strengthened Variants
- Cold Rolled, Bake Hardenable Variants
- Cold Rolled, Micro-alloyed High-Strength Low-Alloy Variants
- Hot Rolled, Micro-Alloyed High-Strength Low-Alloy Variants
The steel sheet may achieve its final thickness by cold rolling, hot rolling, continuous thin-strip casting, or
other means. All requirements of the specific variant are to be
