Carbon steels contain carbon as the key alloying element. They also contain up to 0.4% silicon and 1.2% manganese. In addition, residual elements such as copper, molybdenum, aluminium, chromium and nickel are present. AISI 1038 carbon steel is a medium high carbon steel with good weldability and machinability. This steel can be strengthened by heat treatment after forming.
