TP316LN/S31653/1.4429 Material Summary

316LN (UNS S31653) is a low-carbon, nitrogen-enhanced version of Type 316 molybdenum-bearing austenitic stainless steel. 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. The nitrogen in Type 316LN adds additional resistance to sensitization in some circumstances.
The nitrogen content of Type 316LN stainless steel also provides some solid solution hardening, raising its minimum specified yield strength compared to Type 316L stainless steel. Like Types 316 and 316L, the Type 316LN alloy also offers good resistance to general corrosion and pitting/crevice corrosion.

Main properties of 316LN are: high ductility, good weldability. Typical applications are food and beverage processing industry, chemical industry and chemical tankers.
