S960MC
1.8799Ultra-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.
