CAST STEEL VALVES
The ASTM A 351 specification covers austenitic steel castings for valves, flanges, fittings, and other pressure-containing parts. The most common grades are ASTM A351 CF3, CF8 (SS304), and CF8M (SS316). The steel shall be made by the electric furnace process with or without separate refining such as argon-oxygen decarburization.

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.
What is the difference between CF8M vs SS316 | JC Casting
Sometimes 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.
