بیشترThe 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%.

بیشترAlthough ASTM grade CF8M and AISI 316 are both austenitic stainless steels, AISI 316 is nonmagnetic as a result of it is basically austenite. 316L is rather more weld friendly than 316, as it is much less susceptible to intergranular corrosion, after welding or air service as much as 1600 °F °F, because of carbide precipitation.

بیشترCF8M and CF8 stainless steels are both austenitic stainless sheets of steel, meaning they are non-magnetic and have a high degree of corrosion resistance. CF8M is a cast version of stainless steel, while CF8 is a wrought version. The main difference between CF8M and CF8 stainless steel is their chemical composition.
