Cast steel is iron with an addition of 0.1 to 1.7 percent carbon. It is therefore an alloy between Iron (Fe) and carbon (C). Steel can also contain other elements, but the main part remains iron. The reason why other elements are sometimes added has to do with the application area of the material. The quality of steel can be influenced by means of alloys. Also thermal treatments can ensure that the properties of steel are influenced. By means of thermal ‘hardening’ the abrasion resistance and thus the hardness of an alloy can be improved. This is a process in which steel (or other metal or alloy) is first heated and then cooled (tempered). By means of these treatments, the mechanical properties of steel can be adapted to the requirements that have to be made of the product to be manufactured with it. The properties that steel has are good in terms of strength and toughness. To produce a casting, a three-dimensional impression of the final product in a sand mold is required.With the casting process, both semi-finished and finished products can be poured.Casting is often the shortest route to a product. When the required tolerances and surface quality are achieved, further post-processing is not necessary.If these requirements are exceeded, the product still has to be processed after it has been processed. This is often done by machine machining.
