CF8M stainless steel is the most widely used US standard austenitic stainless steel casting grade. Its equivalent type is cast 316. From the name CF8M, the letter "C" means the alloy is mainly for the purpose of corrosion resistance. The letter "F" is the approximate location on the iron-chromium-nickel (FeCrNi) ternary diagram.

A forged valve body is produced by forging and machining solid steel. The key specifications for cast steel valves body materials are ASTM A216 (WCA, WCB, WCC), ASTM A352 LCB/LCC (low-temperature), and ASTM A351 CF8/CF8M. ASTM A105, A350 and A182 cover body materials for small size (or high pressure) forged valves.
