SA-351 CF8M Stainless Steel Casting | CF8M material

CF8M stainless steel is the most widely used US standard austenitic stainless steel casting grade. Its equivalent type is cast 316. From the name CF8M, the letter "C" means the alloy is mainly for the purpose of corrosion resistance. The letter "F" is the approximate location on the iron-chromium-nickel (FeCrNi) ternary diagram.

CF8M vs CF3M Stainless Steel

The chemical composition of stainless steel can be divided into two broad categories: austenitic and ferritic. While CF8M and CF3M are part of the austenitic family, they also differ in their composition. The main component that sets them apart from each other is chromium content; CF8M contains 8-10% chromium, while CF3M contains 3-4%.
