Material 1.4429-ESU (316LN) According to CERN Specification 316L Stainless Steel Round Bar
ASTM A240/A240M AISI 316LN DIN 1.4429 Stainless Steel Plate 2B and NO.1 Finish
316LN (UNS S31653) is a lowcarbon, 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.
