Type 316 is an austenitic chromium nickel stainless steel. It also contains molybdenum which increases its general corrosion resistance as well as the mechanical properties at elevated temperatures. The properties of type 316 are similar to type 304; however 316 is stronger at elevated temperatures amd also corrosion resistance is improved particularly against sulphates, phosphates and other salts as well as reducing acids such as sulphuric, sulphurous and phosphoric. Type 316L is an extra low carbon version of type 316.
