Cast carbon steel is the group of the cast steel with carbon as the main alloying element and a small amount of other elements. Cast carbon steel can be divided into cast low carbon steel, cast medium carbon steel and cast high carbon steel. The carbon content of cast low carbon steel is less than 0.25%, the carbon content of cast carbon steel is between 0.25% and 0.60%, and the carbon content of cast high carbon steel is between 0.6% and 3.0%.
The strength and hardness of cast carbon steel increase with the increase of carbon content. Cast carbon steel has the following advantages: lower production cost, higher strength, better toughness and higher plasticity.
Carbon steel castings could be used for bear heavy loads, such as steel rolling mill stands and hydraulic press bases in heavy machinery. It can also be used to manufacture parts that are subject to large forces and impact, such as wheels, couplers, bolsters and side frames on railway vehicles.
