316 is generally collectively, often refers to the rod material, forgings, pipe fittings, etc
F316 is the forging material, P316 is the fittings material
CF8M is in the 316 all-cast form. Different forms of uses are 316 materials are composition content is different,
The valve piece, generally said that 316 refers to the forging valve body or rod material production valve body, CF8M is the cast valve body.
