Alloy 316/316L Stainless Steel

Applications

Exhaust manifolds, Furnace parts, Heat exchangers, Jet engine parts, Pharmaceutical and photographic equipment, Valve and pump trim, Tubing, Chemical equipment, Digesters, Tanks, Evaporators, Paper and textile processing equipment, Food processing equipment, and Marine parts.

Description

Type 316 is an austenitic chromium-nickel-stainless steel containing molybdenum. This addition increases general corrosion resistance, improves resistance to pitting from chloride ion solutions, and provides increased strength at elevated temperatures. Properties are similar to those of Type 304/304L except that this alloy is somewhat stronger at elevated temperatures. Corrosion resistance is improved, particularly against sulfuric, hydrochloric, acetic, formic and tartaric acids; acid sulfates and alkaline chlorides. Type 316L is an extra-low carbon version of Type 316 that minimizes harmful carbide precipitation during welding.
