36011 C55K steel plate, is also known as UNE 36011 C55K steel plate, which is under UNE 36011 standard, so we can regard 36011 C55K steel plate as high carbon steel.
36011 C55K steel plate is one mainly high carbon steel. UNE 36011 C55K steel plate is a medium carbon steel which is used when greater strength and hardness is desired other than in the "as rolled"condition. Extreme size accuracy,straightness and concentricity combined to minimize wear make 36011 C55K steel possess wide applications. Processing technologies include turned,ground and polished.The 36011 C55K steel is widely applied in quenched and subsequently tempered steel for less exacting springs,shafts,bushings,crankshafts,etc.
