EN 10083‑2 Grade C60R: Normalized & Normalized‑Formed Steel for High‑Load Applications

Steel C60R is suitable for high loaded parts in vehicle manufacturing, engine and machine engineering requiring improved workability while maintaining constant strength properties (e.g. gear wheels, pinions, shafts). As a bright steel product it is used in the form of bars, bright, straight, in different conditions (see DIN EN 10277).
