text: This is cast Stainless alloy., it is Widely used in pumps, valves, and fittings. All corrosion resistant alloys have theletter C plus a second letter (A to N) denoting increasing nickel content. Numerals indicate\nmaximum carbon. Typical members of this group are CF-8, similar to 304 stainless; CF-\n8M, similar to 316; CF3M, similar to 316L and CD4M Cu, which has improved resistance\nto nitric, sulfuric, and phosphoric acids
