Type 316 is an austenitic chromium-nickel stainless steel containing molybdenum. By that type 316 has increased general corrosion resistance, improved resistance to pitting from chloride ion solutions, and provides increased strength at elevated temperatures. This alloy is stronger than 304 at elevated temperatures. Type 316 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 due to welding. Type 316L is used extensively for weldments where its immunity to carbide precipitation due to welding assures optimum corrosion resistance. Alloy 316/316L is non-magnetic in the annealed condition, but can become slightly magnetic as a result of cold working or welding. It can be easily welded and processed by standard shop fabrication practices
Application and typical uses of type 316L\316 includes exhaust manifolds, food and beverage processing, furnace parts, heat exchangers, jet engine parts, pharmaceutical and photographic equipment, pharmaceutical processing, valve and pump trim, chemical equipment, digesters, tanks, evaporators, semiconductors, process engineering, pulp, paper and textile processing equipment, parts exposed to marine atmospheres and tubing, oil, gas and chemical industries various uses for its cost effective corrosion resistance and ease of fabrication.
