UNE36011 C45K steel plate high carbon steel
C45K 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.
UNE 36011 C45K steel Applications
Quenched and subsequently tempered steel for screws, forgings, wheel tyres, shafts, sickles, axes, knives, wood working drills, hammers, etc.
