High yield strength thermomechanically rolled steel for cold forming with minimum yield strength 550 MPa. The highest alloy quality grade in EN 10149-2 (grades above 550 are alloy special steels). Fine-grained microstructure provides excellent cold bending, folding, and flanging properties. Used for automotive chassis components, crane booms, trailer frames, agricultural machinery, and structural cold-formed sections.

High yield strength alloy special steel for cold forming with minimum yield strength 600 MPa. Thermomechanically rolled. Classified as alloy special steel per EN 10020 (unlike S550MC and below which are alloy quality steels). Used for demanding automotive structural components, heavy-duty trailer and truck chassis, crane and lifting equipment, and mining machinery where high strength with cold formability is critical.

High yield strength alloy special steel for cold forming with minimum yield strength 650 MPa. Thermomechanically rolled. Bridges the gap between S600MC and S700MC in the EN 10149-2 series. Used for weight-optimized automotive and commercial vehicle components, heavy-duty chassis, and structural members requiring excellent cold formability at very high strength levels.

Ultra-high-strength alloy special steel for cold forming with minimum yield strength 960 MPa. The highest strength grade in EN 10149-2. Thermomechanically rolled delivery. Must not be heated above 400°C to preserve mechanical properties. Extraordinary strength-to-weight ratio for cold-formed components. Used in the most demanding automotive, crane, mining, and military vehicle applications where every kilogram counts.
