CG8M (USA Standard), austenitic stainless steel, is the common “300” series general corrosion resistant material used in stainless steel casting process. The chemical composition of CG8M is similar to that of stainless steel 317.
Components made from CG8M Stainless Steel Casting can achieve good strength, wear and galling resistance. Exceptional toughness.
