Plugs Caps & Locknuts St/Steel Range

These grades of austenitic stainless steels are similar to 304 and 304L, but with the addition of molybdenum. The addition of molybdenum improves the alloys corrosion resistance, particularly with higher resistance to pitting and crevice corrosion in chloride environments.

Though the stainless steel 304 alloy has a higher melting point, grade 316 has a better resistance to chemicals and chlorides (like salt) than grade 304 stainless steel. When it comes to applications with chlorinated solutions or exposure to salt, grade 316 stainless steel is considered superior.
