Stainless Steel 316
Material Data Sheet
Type 316 Stainless Steel is widely used in applications requiring corrosion resistance superior to Type 304, or good elevated temperature strength. Typical uses include exhaust manifolds, furnace parts, heat exchangers, jet engine parts, pharmaceutical and photographic equipment, valve and pump trim, chemical equipment, digesters, tanks, evaporators, pulp, paper, and textile processing equipment, parts exposed to marine atmospheres, and tubing. Type 316L is used extensively for weldments where its immunity to carbide precipitation due to welding assured optimum corrosion resistance.
