Type 316 / 316L

Stainless Steel

316 - 316L Stainless Steel

Type 316 is an austenitic stainless steel with added molybdenum which gives the alloy improved corrosion resistance. It is commercially almost as popular as 304 stainless. The mechanical properties of the alloy are similar to Type 304 except that this grade is stronger at elevated temperatures. Type 316L is a low carbon version of Type 316 which minimizes carbide precipitation due to welding.


Weldability of 316 alloys is excellent, and machinability is good. Corrosion resistance is good - excellent pitting resistance and good resistance to most chemicals involved in such industries as paper, photographic and textiles.


Type 316 stainless steel is an austenitic grade with added molybdenum. The alloy offers improved corrosion resistance when compared with Type 304, particularly in chloride environments. Type 316L should be used for welding applications.
