Grade Introduction:
Carbon steels have carbon as the key alloying element in their composition. They also contain up to 0.4% silicon and 1.2% manganese. In addition, the residual elements such as copper, molybdenum, aluminum, chromium and nickel are present in these steels.
55C8 is a water resisting carbon steel whose wear resistance and hardenability are increased by the addition of small quantity of chromium
