Product Description
XM-19 / UNS S20910 Stainless Steel provides a combination of corrosion resistance and strength not found in any other commercial material available in its price range,is a highly fabricable, highly weldable, nitrogen strengthened, austenitic stainless steel
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 / UNS S20910 has very good mechanical properties at both elevated and sub-zero temperatures. And, unlike many austenitic stainless steels, XM-19 does not become magnetic when cold worked.
Material type XM-19 / UNS S20910 : High nitrogen strengthened austenitic stainless steel, non-magnetic and possessing high strength (yield strength ≥ 380 MPa) and excellent corrosion resistance, with performance superior to 316 stainless steel
