But the casting property is less than iron. Strength of steel castings are higher than iron castings. Such steel castings are widely used in crushing, screening, tunnel drilling and mining industries. Special steel castings are casted from materials added high ranges of alloy elements, such as Mn and/or Cr, which can help to increase the wear resistantance and impact resistantance of the castings. Alloy steel castings are made by adding some Mn, Cr & Cu into the carbon steel, which can help to less the weight of the castings and longer the lifetime of the components. So, such castings are widely used in making heavy loading components, such as hydraulic equipment basises, wheels, hooks, etc.

Finished carbon steel castings are with higher strength, plasticity and toughness. With increasing of the C elements, the strength and hardness of the castings will be increased. Castings made in carton steel with percentage of C≤0.25% is called low carbon steel castings. Cast carbon steels refer to steels with Carbon elements ranging from 0.2%-0.5%.

So, nowdays, a lot of machinery parts are choosen to be casted from steel materials.Ĭast steel in our foundry includes carbon steels, alloy steels, and special steels. Steel casting is one of the core casting process in our investment casting foundry in China.Ĭompare with iron casting, components casted by steel casting technics are with high strength and impact resistant.
