In type 316, the nickel content is increased slightly. What distinguishes Type 316 from Type 304 is the
addition of molybdenum up to a maximum of 3%. Type 316 can withstand corrosive attack by sodium
and calcium brines, hypochlorite solutions, phosphoric acid; and the sulfite liquors and sulfurous acids used in the paper pulp industry. This alloy, therefore, is specified for industrial equipment that handles the corrosive process chemicals used to produce inks, rayons, photographic chemicals, paper, textiles, bleaches, and rubber.
