High Hardness Austenitic Stainless Steel Pipe Nitronic50 UNS S20910 / NAS XM-19

Introduction:

Nitronic 50 / S20910 is a nitrogen-reinforced austenitic stainless steel, which has better corrosion resistance than 316, 616L, 317, and 317L, and has almost twice the yield strength at room temperature. This steel grade has very good mechanical properties at both high and sub-zero temperatures. S20910 can maintain very low magnetic permeability even after large cold deformation or at sub-zero temperature, and has very good mechanical properties at 1200 ° F (649 ° C).
