316 Stainless Steel

316 Stainless steel is second only to Type 304 in total production.

Type 316 has almost the same physical and mechanical properties as 304 stainless steel, and contains a similar material make-up.  The difference being the addition of 2 to 3 percent molybdenum.  This addition gives Type 316 corrosion resistance, particularly against chlorides and other industrial solvents. 

We can supply Type 316  in sheets/plates. bars and angles.  Get in touch with us for the best prices.

316 Stainless Steel Bar Grinding Services

  • 316 is an austenitic chromium-nickel stainless steel containing molybdenum to increase general corrosion resistance, resistance to pitting and strength at elevated temperatures.
  • Properties similar to Type 304 except that Type 316 is somewhat stronger at elevated temperature, and has better corrosion resistance

316L Stainless Steel

  • Extra low carbon version of Type 316 that eliminates harmful carbide precipitation due to welding

Typical Applications

  • Widely used in a variety of applications requiring superior corrosion resistance or good elevated temperature strength
  • Applications include valve parts, pumps, tanks, evaporators and agitators, textile processing equipment and a wide variety of parts exposed to marine atmospheres
  • Type 316 L is used extensively for weldments where its immunity to carbide precipitation due to welding assures optimum corrosion resistance

  • 316 stainless steel is somewhat more difficult to machine than Type 304 because of its toughness.
  • As large a tool as possible and great amounts of cutting fluid should be used.
  • Heavy feeds at slow speeds will machine best.


  • Types 316 and Type 316L can be readily drawn and formed.

Heat Treatments

  • ANNEALING: Material is heated to 1950-2050° F, cooled rapidly in air or water quenched.


  • Forging is done by heating to 2200-2300?F and forging.
  • No forging should be done below 1700?F.
  • Material should be cooled rapidly after forging and hot forming.

Corrosion Resistance

  • Type 316 provides better corrosion resistance than Type 304.
  • It has excellent resistance to pitting type corrosion such as encountered in sea coast environments.
  • It also has good resistance to most chemicals involved in the paper, textile and photographic industries.

Welding 316 Stainless Steel

  • Type 316 and 316L have excellent weldability and are readily joined by all methods employed with stainless steel.
  • Weldments of Type 316 may require annealing to restore maximum corrosion reisistance.
  • Type 316L eliminates the necessity for annealing except where required for stress relief.
