316 steel is an austenitic chromium-nickel stainless steel that contains between two and 3% molybdenum. The molybdenum content increases corrosion resistance, improves resistance to pitting in chloride ion solutions, and increases strength at high temperatures. Type 316 grade stainless steel is particularly effective in acidic environments.

Grade 316 Stainless Steel is the standard molybdenum-bearing grade. The molybdenum gives 316 better overall corrosion resistant properties than Grades 302 and 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. It is readily brake or roll formed into parts for applications in the industrial, architectural, and transportation fields. Grade 316 also has outstanding welding characteristics.
