Type 316 is an electric furnace processed modification of Type 304: it contains 18% chromium; 10% nickel, and; 2-3% molybdenum. This addition of molybdenum increases both the corrosion resistance and the high temperature strength of this alloy. The most outstanding advantage of this addition is the increased corrosion resistance to reducing acids and pitting or pin hole corrosion. In general, Type 316 is known as the major all-around corrosion resistant austenitic stainless steel available. Under extremely elevated temperatures, Type 31 6 proves itself to possess remarkable creep and rupture strength, This non-heat treatable, non-magnetic alloy possesses excellent cold forming and drawing properties, making it suitable for a wide range of applications. Type 316L is an extra low carbon modification of Type 316 recommended for use during welding operations. The low carbon factor eliminates the possibility of harmful carbide precipitation in the 800° F. to 1500° F. range.

Applications

Type 316 and Type 316L find their greatest use in the chemical, textile, paper, pharmaceutical, and photographic industries because of their excellent resistance to chemical corrosion. They also find use where the combination of corrosion resistance and extremely high strength at elevated temperatures is necessary.

Corrosion Resistance

Type 316 is known to be more resistant to atmospheric and chemical corrosion than any other grade of the stainless steels. Maximum corrosion resistance may be obtained by fully anneal­ing this alloy. If the application calls for welding, Type 316L should be used as it is highly resistant to carbide precipitation and intergranular corrosion. Which usually occurs at high temperatures.
