Carbon Steel Investment Castings

Carbon steel investment castings are the custom castings produced by lost wax investment casting process (or called precision casting). Cast carbon steel is the kind of cast steel with carbon as the main alloying element and a small amount of other elements. They 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 medium 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 kinds of advantages such as lower production cost, higher strength, better toughness and higher plasticity. Cast carbon steel castings can be used to manufacture parts that bear heavy loads, such as tractor spare parts, railroad freight cars, automotible, steel rolling mill stands, 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.
