316 Machining, Properties & Components

What is 316?

316 is an austenitic grade of stainless steel, second only to 304 in commercial importance. 

It has improved corrosion resistance due to the addition of molybdenum. This makes it a little more expensive than 304.

316L is the low carbon version of 316.

Main Attributes of Stainless 316:

  • Excellent corrosion resistance (wider range of chemicals than 304)
  • Performs well when exposed to relatively high and sub-zero temperatures
  • Easily machined
  • Suited to all standard methods of welding
  • Subject to pitting and crevice corrosion in warm chloride environments
  • Ease of cleaning
  • Subject to stress cracking above 60°c
  • Good heat resistance – oxidation resistance in intermittent use up to 870°c and continuous use up to 925°c, however continuous use at 425-860°c is not recommended. In this instance, 316L is recommended.
