As regards to its mechanical properties cast steel is in many ways superior to grey and spheroidal iron. Steel is foremost used as a material when a clear thermal or chemical resistance or high solidity is needed. Castings from steel are therefore mainly used in shipbuilding, in engineering, in the automotive industry and in plant construction.
Further on, steel is well suitable for welding, is malleable and through special production procedures and after-production processes it can offer a high variety of materials. As examples we can mention stainless steels here. Also material classifications such as V2A (1.4301) and V4A (1.4571) are common, yet they represent only an excerpt from the cast steel portfolio resp. stainless steel cast portfolio of the Esterer Foundry.
The reason for exceptional characteristics of steels is the low share of carbon which is under 2.06 per cent.
