General Information
Alloys 316 (UNS S31600) and 316L (UNS S31603) are molybdenum-bearing austenitic stainless steels, which are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Alloy 304. These alloys also offer higher creep, stress-to-rupture, and tensile strength at elevated temperatures. In addition to excellent corrosion resistance and strength properties, the Alloys 316 and 316L Cr-Ni-Mo alloys also provide excellent fabricability and formability which are typical of the austenitic stainless steels.
Alloy 316/316L resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. It also resists corrosion in polluted marine atmospheres. The alloy has excellent resistance to intergranular corrosion in the as-welded condition. Alloy 316/316L has excellent strength and toughness at cryogenic temperatures
Key Features:
- Higher resistance to pitting corrosion and crevice corrosion in seawater than Alloy 304 stainless steel
- Pitting Resistance Equivalent number (PREN) of 25 compared with 19 for Alloy 304
- Excellent ductility and impact strength at both ambient and sub-zero temperatures
- Low carbon version of Alloy 316 thereby immune from grain boundary sensitisation
- Excellent forming and welding characteristics
- Non-magnetic except after significant welding or cold working
