316 Stainless Steel
Grade 316 is an austenitic grade second only to 304 in commercial importance. 316 stainless steel contains an addition of molybdenum that gives it improved corrosion resistance.
316 Stainless steel is second only to Type 304 in total global steel production.
Type 316 has almost the same physical and mechanical properties as 304 stainless steel and contains a similar material make-up. The difference being the addition of 2 to 3 percent molybdenum. This addition gives Type 316 corrosion resistance, particularly against chlorides and other industrial solvents.
We can supply Type 316 in sheets/plates. bars and angles. Get in touch with us for the best prices.
316 Stainless Steel Properties and Specifications
316 is an austenitic chromium-nickel stainless steel containing molybdenum to increase general corrosion resistance, resistance to pitting, and strength at elevated temperatures. It has properties similar to Type 304 except that Type 316 is somewhat stronger at elevated temperature and has better corrosion resistance
The following specifications are generally applicable to Type 316 :
Sheets and Plates
- MIL-S-5059
- ASTM A 167
- ASTM A 240
- QQ-S-76
Bars and Angles
- MIL-S-7720
- AMS 5648
- QQ-S-763
- ASTM A 276
- ASTM A 479
- Widely used in a variety of applications requiring superior corrosion resistance or good elevated temperature strength.
- Applications include valve parts, pumps, tanks, evaporators and agitators, textile processing equipment, and a wide variety of parts exposed to marine atmospheres.
- Type 316 L is used extensively for weldments where its immunity to carbide precipitation due to welding assures optimum corrosion resistance
316L Stainless Steel
- Extra-low carbon version of Type 316 that eliminates harmful carbide precipitation due to welding
