316/316L Stainless Steel


Much like 304 Stainless Steel, 316 Stainless has good formability, weldability, and corrosion resistance. Due to a higher molybdenum and nickel content, 316 has the highest corrosion resistance in it's class. Common uses for this material include medical devices, chemical processing, marine environments, and oil & gas.

Armour Alloys
Sheet, Plate, Coil
Pulp and paper equipment, heat exchangers, dyeing equipment, photographic developing equipment, propeller shafts, fittings, exterior architectural components in marine coastal areas.
Highly resistant to the complex Sulphur compounds used in pulp and paper processing. Also resists attack by marine and corrosive industrial atmospheres
Good oxidation resistance in intermittent service to 1600° and in continuous service to 1700°F. Continuous use in the 800 – 1575°F range not recommended but often performs well in temperatures fluctuating above and below this range. Type 316L is more resistant to carbide precipitation and can be used in the above temperature range.
Annealing – Heat to 1850°F – 2050°F, and cool rapidly for maximum corrosion resistance. 316 grades cannot be hardened by thermal treatment.
