316 Stainless Steel Material Properties

316 Stainless Steel

316 SS (Stainless Steel) is an austenitic form of stainless steel which contains 2 to 3 % of molybdenum. This added molybdenum makes the metal more resistant to corrosion, pitting and improves its resistances at elevated temperatures  as well as provides greater resistance to acids and localized corrosion caused by chloride ions.  

316 SS has qualities such as corrosion resistance, high strength, and high concentrations of chromium and nickel. Furthermore, 316L, the low carbon version of Stainless steel 316, is immune to grain boundary carbide precipitation.

Applications

316 SS is used in most of industrial application, few of them are listed below:

  • Pressure vessel, heat exchangers.
  • Food preparation equipment particularly in chloride environments.
  • Laboratory benches & equipment.
  • Coastal architectural paneling, railings & trim.
  • Chemical containers, including for transport.
  • Woven or welded screens for mining, quarrying & water filtration.
  • Threaded fasteners, Springs, etc.
