1.Introduction

Nitronic 50 Stainless Steel provides a combination of corrosion resistance and strength not found in any other commercial material. This austenitic stainless steel has corrosion resistance greater than that provided by types 316, 316L, 317, 317L plus approximately twice the yield strength at room temperature.

In addition, Nitronic 50 has very good mechanical properties at both elevated and sub-zero temperatures unlike many austenitic stainless steel grades.Nitronic 50 does not become magnetic in cryogenic situations.

High Strength (HS) Nitronic 50 has a yield strength about three times that of 316 Stainless Steel.

XM-19 Stainless Steel, a highly fabricable, highly weldable, nitrogen strengthened, austenitic stainless steel, provides twice the yield strength of stainless steel type 316 and a resistance to corrosion equivalent to type 316. Even after extreme forming, XM-19 Stainless Steel stays non-magnetic. Due to all these advantages, it is often used in boat shafting, marine hardware, pumps, valves, and fasteners. The machinability of XM-19 Stainless Steel is comparable to that of alloy 316 or 317. It is formable, but there will be more springback with XM-19 than with other austenitic stainless steels. To achieve maximum hardness, use cold working. Because of XM-19's high tendency toward work hardening, process anneal the work piece after forming to relieve stress.
