Product Description

ASTM 316LN / SUS316LN / 1.4429 Seamless Stainless Steel Pipe

UNS S31653 / 316LN Austenitic Stainless Steel Pipe

316LN (UNS S31653) is a low-carbon, nitrogen-enhanced version of Type 316 molybdenum-bearing austenitic stainless steel. The Type 316 alloys offer superior resistance to general corrosion and pitting/crevice corrosion compared to conventional chromium-nickel austenitic stainless steels like Type 304. They also provide higher creep, stress-rupture and tensile strength at elevated temperatures.

The nitrogen content in Type 316LN stainless steel provides additional resistance to sensitization and offers solid solution hardening, increasing its minimum specified yield strength compared to Type 316L stainless steel.

316LN stainless is a single phase austenitic (face centered cubic) stainless steel at all temperatures up to the melting point. The alloy cannot be hardened by heat treatment. The alloy is nonmagnetic in the annealed condition with magnetic permeability typically less than 1.02 at 200 H (Oersteds).

Fatigue Resistance

The fatigue strength or endurance limit is the maximum stress below which a material is unlikely to fail in 10 million cycles in an air environment. For austenitic stainless steels, the fatigue strength is typically about 35 percent of the tensile strength.
