EN 10083-2 Grade C35 Quenched & Tempered Steel – Ideal for High‑Strength Automotive & Industrial Applications
Steel C35 is suitable for components of slightly higher strength requirements and still low ductility requirements in vehicle manufacturing, engine and machine engineering (e.g. gears, bolts, clutch parts). Lowest working temperature -25 °C, favorable creep behaviour up to 480 °C.
