AISI 316LN (UNS S31653) is a low carbon and nitrogen enhanced version of stainless steel 316. 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than traditional chromium-nickel austenitic stainless steels such as 304. They also have higher creep, stress rupture and tensile strength at elevated temperatures. The nitrogen in AISI 316LN increases resistance to sensitization in some cases and also provides some solid solution hardening, increasing its minimum specified yield strength compared to 316L stainle
ss steel. Like 316 and 316L stainless steels, AISI 316LN alloys also resist general corrosion and pitting/crevice corrosion very well.
JN is 316ln stainless steel supplier form China, UNS S31653 products include: 316ln plate, 316ln tube, 316ln rod, 316ln flange, 316ln forging, 316ln pipe fittings, 316ln fasteners, etc.
Its nitrogen content provides solid solution hardening, increasing the minimum specified yield strength.
Excellent resistance to oxidation and low rate of scaling at temperatures up to 1650°F.
Provides more resistance to atmospheric and other types of corrosion.
Is considered one of the most weldable of the stainless steels.
Hot forming can be performed in the range of 1560 – 2100 ⁰ F.
Type 316LN can be formed and fabricated by any cold forming operation.
