The ASM Metals Handbook lists both CF-8M and CF-12M as being the nominal cast equivalents of 316SS even though CF-12M has slightly higher C content than CF-8M. It also notes that this is just a nominal equivalent between wrought and cast products. The chemistries of the two metals are not identical. CF-8M has higher Cr, S, …

CF8M is a versatile austenitic stainless steel that offers good corrosion resistance and strength. It has excellent weldability and formability, making it a popular choice for many applications. UNS Number of Cf8M Material is J92900. The CF8M material specification covers the chemical and mechanical requirements for this grade of stainless …
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%.
CF8M is defined in ASMT A351, ASMT A743 and ASTM A744, which is for casting purpose only. SS316 is defined in ASTM A240 and ASTM A276, it's for plate, sheet, strip or …

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.
The most significant difference is that A351 has tensile property, inspection, and quality requirements not found in A743. A351 references A703 which in turn sets out the testing & analysis methods and requirements. A743 references A781, a general specification for casting used in non-pressurized applications.
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 …
