316LN (UNS S31653) stainless is a low-carbon, nitrogen-enhanced version of Type 316 molybdenum-bearing austenitic stainless steel. It is also known as DIN/EN designation No. 1.4406. The Type 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304. They also offer higher creep, stress-rupture and tensile strength at elevated temperature. 316 stainless steel can be susceptible to sensitization the formation of grain boundary chromium carbides at temperatures between approximately 900 and 1500 F (425 to 815 C) which can result in rapid corrosion. Reduced carbon 316L alloy is resistant to sensitization; however, extended exposures in this temperature range will eventually result in sensitization of even the low carbon grade.
The nitrogen in 316LN alloy adds additional resistance to sensitization in some circumstances. The nitrogen content of 316LN stainless steel also provides some solid solution hardening, raising its minimum specified yield strength compared to 316L stainless steel. Like 316 and 316L alloys, the 316LN alloy also offers excellent resistance to general corrosion and pitting/crevice corrosion.
