  EN 10083 C40 steel plate high carbon steel
  C40 steel plate, EN 10083 C40 steel plate, under EN 10083 standard, we can regard C40 steel plate as high carbon steel.
  
  C40 steel plate is one mainly of high carbon steel,EN 10083 C40 steel plate is meduim Carbon Steels are similar to low carbon steel except that the carbon ranges from 0.30 to 0.60% & the manganese from 0.50 to 1.65%. Increasing the carbon content is approximately 0.5% with an accompanying increase in manganese allows medium carbon steels to be used in the quenched & tempered conditions. This steels are of particular importance because of unique combination of strength & toughness after heat treat treatment.
