Type 316 is a chromium-nickel stainless steel modified by the addition of molybdenum, which greatly increases its corrosion resistance as well as its mechanical properties at elevated temperatures. It is non-magnetic in the annealed condition and not hardenable by heat treatment. It is an outstanding stainless steel suitable for large numbers of applications. It is also available in an extra low carbon analysis, Type 316L.

Applications: Widely used in the paper, textile and chemical industries, where parts are subjected to the corrosive effects of salts and reducing acids. Also used in the manufacture of pharmaceuticals in order to avoid excessive metallic contamination. Since Type 316 possesses the highest creep and tensile strength at elevated temperatures of any of the more commonly used stainless steels, it finds extensive use where the combination of high strength and good corrosion resistance at elevated temperatures is required. In aircraft applications, Type 316 is used for parts requiring good corrosion resistance and low magnetic permeability.

Corrosion Resistance: Type 316 is more resistant to atmospheric and general corrosive conditions than any of the other standard stainless steels. It has good resistance to the corrosive effects of sulphates, phosphates and other salts as well as reducing acids such as sulphuric. sulphurous and phosphoric. It is less susceptible to pitting in applications where acetic acid vapors or solutions of chlorides, bromides or iodides are encountered. When heated to within the temperature range of 8O0-15O0 Deg. F or when slowly cooled through this range, this grade is subject to intergranular corrosion.

Resistant To Scaling: Excellent scale resistance at temperatures up to 1650 F in continuous Service.

Machinability: Type 316 has a machinability rating of approximately 36% with B-1112 rated 100%. Surface cutting speed on automatic screw machines isapproximately 60 feet per minute.

Weldability: Easily welded by all the commercial processes except forge or hammer welding. Annealing after welding is recommended to obtain maximum corrosion resistance.

Forming: This grade has good drawing and stamping properties.

Forging: Forge between 2100 and 2300 Deg. F Do not forge below 1700 Deg. F.

Annealing: Annealing range is between 1850 and 2050 Deg. F Cool rapidly. Water should be used for heavier sections, air for lighter sections. The stress relieving range is between 400 and 750 Deg. F.
