CF8M and CF3M are two different types of austenitic stainless steel with distinct differences between them. While they share similar mechanical properties such as tensile strength and elongation values, their chemical compositions set them apart from each other—with the major difference being the amount of chromium present within each …
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 according to our …

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.
Applications. Valves, flanges, fittings, and other pressure-containing elements use CF8M material. The austenitic stainless steel CF8M provides great applicability for items requiring high overall corrosion resistance. It provides good strength and …
