• Detailed Description:

  DIN 17200 C55 steel plate high carbon steel
  C55 steel plate, DIN 17200 C55 steel plate, under DIN 17200 standard, we can regard C55 steel plate as high carbon steel.
  
  C55 steel plate is one mainly of high carbon steel,DIN 17200 C55 steel plate is a
  medium carbon steel which is used when greater strength and hardness is desired than in the "as rolled"condition.Extreme size accuracy,straightness and concentricity combined to minimize wear in high speed applications.Turned,ground and polished.The C55 steel is applied in quenched and subsequently tempered steel for less exacting springs,shafts,bushings,crankshafts,etc.
