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 …

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.

Overview. CF8M / 316 stainless steel is a modification of 304 stainless steel with the addition of 2.0% to 3.0% molybdenum to provide improved resistance to reducing corrosives and pitting attack by chlorides as found in seawater. Careful balance of the chemical composition strengthens this alloy to levels well above most specifications.

ASTM A351 CF8 is the equivalent investment cast alloy of AISI 304 stainless steel, which belongs to austenitic stainless steel that presents good strength and ductility. As the chemical composition of CF8 includes approximately 18% chromium and 8% nickel by weight, it is also known as 18/8 stainless steel.
