Unlike CF8M and CF3M of ASTM A351, CF8C grade has option for stabilization treatment due to Nb present which forms carbides, between 870 and 900 °C after solution annealing in austenite matrix. This prevents depletion of chromium around grain boundary and prevents sensitization of steel. However, this stabilization treatment …
بیشترSometimes we regard CF8M equals to Stainless steel 316. Actually, SS316 is the general name for 316 stainless steel. CF8M is a pressure-bearing component, austenitic stainless steel casting. Executive standard: ASTM A351-2018. CF8M is one type of 316 stainless steel. The chemical composition of CF8M is as follows: Content.
