It is a form of 316 Stainless Steel As to the designation - C (first letter) means the service it is intended to be used in this case - corrosion resistant service , F(second letter) -The second letter indicates the approximate location of the alloy on the iron-chromium-nickel (FeCrNi) ternary diagram. For users familiar with the diagram, the second letter does provide an indication of the nominal iron, nickel, and chromium content, but most people would have to obtain alloying information from a material specification. 8M - the third and fourth digits represent the maximum permitted carbon content in units of 0.01% (e.g., CF8M has a maximum of 0.08% carbon)
ASTM A 351 Gr CF8 stands for cast 304 material and CF8M stands for cast SS 316
Stainless Steel version
CF8M is a low-carbon version of CF8, which are both types of stainless steel. CF8M has a higher chromium and nickel content, making it more corrosion resistant than CF8. CF8 is often used in applications where corrosion resistance is less critical compared to CF8M.
