Alloy 316 & 316L Stainless Steel

Austenitic alloy and similar to 304/304L, used in a wide range of applications.

Applications

Very wide ranging. It is practically used almost everywhere:

  • marine industry
  • chemical process vessels
  • heat exchangers
  • food and wine industry
  • pharmaceutical industry
  • water treatment
  • petroleum refining
  • etc.

 

Properties

Alloy 316/316L is an austenitic alloy and similar to 304/304L is used in a wide range of applications. It is an important alloy when it comes to chloride environments and many other chemical process industries. The addition of Molybdenum significantly increases general corrosion resistance as compared to 304/304L and more importantly, increases the chloride pitting resistance.

316/316L has excellent forming and welding characteristics. Due to its superior chloride pitting resistance, it is commonly used in applications involving chlorides or halides. That property is also useful in marine environments.

It also has an excellent resistance to intergranular corrosion in as-welded condition. Dual grade becomes important if heavy gauge welding is performed. This is where intergranular corrosion comes into picture and having a lower carbon version makes it difficult for Chromium Carbide to precipitate in the 797 to 1580 degF (425 to 860 degC) range when the welding is going on for a long time due to the heavy gauge.

It has excellent creep and rupture strength at higher temperatures compared to 304/304L. Finally, it has excellent strength and toughness at cryogenic temperatures.
