CF8 Stainless Steel Casting. AISI 304 or CF8 stainless steel castings means the casting parts made of CF8 stainless steel. It is a general grade, belonging to austenitic stainless steel. It is widely used in the foundry industry. The standard composition of CF8 stainless steel is 18% chromium plus 8% nickel. It is non-magnetic.

The most significant difference is that A351 has tensile property, inspection, and quality requirements not found in A743. A351 references A703 which in turn sets out the testing & analysis methods and requirements. A743 references A781, a general specification for casting used in non-pressurized applications.

Conclusion. In summary, ASTM A351 CF8M stainless steel castings shows better corrosition resistance, while CF8 stainless steel castings have lower cost. The selection of these two alloys mainly depend on the working environment. If you are unfamilar with them, CFS can recommend a good alloy for your cast stainless steel product …
