Although 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.

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.
Cast austenitic stainless steel grade CF8C of ASTM A351 possesses varying degrees of suitability for services both at high temperatures and in corrosive environments. CF8C contain Nb of 1% max as per ASTM A351, i.e. 8 times the carbon content. Unlike CF8M and CF3M of ASTM A351, CF8C grade has option for stabilization treatment due …

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%.
316/316L STAINLESS VALVES. Valves are manufactured in ASTM A182 316/316L forgings and ASTM A351 CF8/CF3 castings. Trim components can also be in UNS S31600 and AISI-SAE 316/316L. Welded end valves can be in 316 but 316L is often preferred due to the lower carbon content which avoids inter granular corrosion in the as-welded state thereby ...
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 …

Differences between CF8M and 304. One major difference between these two stainless steel alloys is their level of corrosion resistance; At the same time, both offer excellent protection from rusting, or corrosion on their own, cf8m offers superior corrosion resistance compared to 304 thanks to its higher molybdenum content.

Mechanical Properties. CF8M and CF8 stainless steels also have different mechanical properties. CF8M has a higher yield strength and tensile strength than CF8, meaning it is better suited for applications that require high strength. However, CF8 has better ductility than CF8M, which is more resistant to cracking during welding.
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 …
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.
