ISO 683-1 Grade C50E Steel – Quenched for Heavy‑Duty Applications
Steel C50E is suitable for larger parts (heavy forged parts) in vehicle manufacturing, engine and machine engineering (e.g. transmission parts, shafts, wheel hubs). As a bright steel product it is used in the form of bars, bright, straight, in different conditions (see DIN EN 10277).
