EN 10083-2 Grade C60R quenched and tempered (+QT)

EN 10083-2 Grade C60R quenched and tempered (+QT) introduction

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).
