JISG4051 S45C steel,S 45 C carbon steel

JISG4051 S45C steel is a medium carbon steel is used when greater strength and hardness is desired than in the "as rolled" condition. Extreme size accuracy, straightness and concentricity combine to minimize wear in high speed applications. Turned, ground and polished.
