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.
XM-19 is composed of between 20% and 23% chromium, 11% to 13% nickel, 4% to 6% manganese, and 1.5% to 3% molybdenum, with the balance being iron. Also found in XM-19 are trace amounts of carbon, silicon, sulfur, phosphorus, nitrogen, columbium (or niobium) and vanadium. As noted previously, it is much stronger than Stainless Steels 316/316L and 317/317L; however, the same fabrication equipment and procedures used for the Stainless Steel 300 grades can be utilized for XM-19. In addition, the same cooling techniques used for Stainless Steels 316/316L and 317/317L can be utilized for XM-19.
