About 316/316L Stainless Steel

Stainless steel 316 (SS316) is an austenitic chromium-nickel stainless steel containing min. 2.5% of molybdenum which increases general corrosion resistance and especially improves its pitting resistance to chloride ion solutions. The molybdenum addition provides increased strength at elevated temperatures. SS316 is also known as “Mo-Added” version of SS304. Stainless steel 316L (SS316L) is the extra-low carbon version of SS316 that minimizes harmful carbide precipitation during welding. Both SS316 and SS316L have exceptional resistance to corrosion against sulfuric, hydrochloric, acetic, formic, and tartaric acids; as well as against acid sulfates and alkaline chlorides.

Stainless Steel 316L pipes and fittings are widely used in exhaust manifolds, heat exchangers, pharmaceutical equipment, cryogenic piping, valve and pump trims, chemical & petrochemical process, pulp and paper industry, and food industry, etc.
