Stainless Steel 316 Properties

Stainless Steel 316 is an austenitic stainless steel renowned for its superior corrosion resistance and high strength, making it an ideal choice for a variety of industrial applications. This alloy contains molybdenum, which enhances its resistance to pitting and crevice corrosion, especially in chloride environments. As a result, SS 316 is widely used in marine, chemical processing, and pharmaceutical industries, where exposure to corrosive substances is common.

One of the standout properties of Stainless Steel 316 is its excellent resistance to oxidation at high temperatures. This makes it a reliable material for use in heat exchangers, furnace parts, and jet engine parts. Additionally, its non-reactive properties make it suitable for medical implants and surgical instruments, where biocompatibility is crucial.

Heat Resistance:

  • Good oxidation resistance at temperatures up to 1700oF (927 oC)
  • Continuous use at temperatures above 1400oF (760oC) is not usually recommended due to carbide precipitation which can lead to irregular scaling
  • Does not have a low carbon content so it is also vulnerable to sensitization

Welding Characteristics:

  • Not generally recommended, but may be welded with some difficulty
  • May be welded with Alloy 310 electrodes
  • Should be annealed after welding to re-dissolve precipitated carbides

Machinability:

  • High machining rates can be obtained in the annealed condition with hardness in the range of 200 to 240 Brinell
  • Will work harden; therefore, it should be machined at reduced surface feet per minute and heavier feeds to prevent glazing at the tool interface.

Applications:

  • Nuts and bolts
  • Aircraft fittings
  • Gears
  • Screws
  • Shafts
  • Electrical switchgear components
  • Bushings
