Factory source Ductile Iron Green Sand Casting - Steel Sand Casting Company – RMC Foundry

Custom Wear-resistant Castings from Sand Casting Company in China with Custom and CNC Machining Services.

Among a wide variety of casting alloys, wear-resistant cast steel is a very widely used alloy steel. Wear-resistant cast steel mainly improves the wear resistance of steel castings by adding different content of alloying elements, such as manganese, chromium, carbon, etc., to the alloy. At the same time, the wear resistance of wear-resistant steel castings also depends on the heat treatment method used by the foundry and the structure of the casting.

Wear-resistant alloy steel sand castings are the casting parts produced by sand casting process made of wear-resistant alloy steel. At RMC Foundry, the main sand casting processes we could use for wear-resistant alloy steel are green sand casting, resin coated sand casting, no-bake sand mold casting, lost foam casting, vacuum casting and investment casting. The heat treatment, surface treatment and CNC machining are also available at our factory as per your drawings and requirements.
