XM-19 Round Bar which is Supply by us have a highly fabric able, 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 Round Bar stays non-magnetic. Because of XM-19's high tendency toward work hardening, process anneals the work piece after forming to relieve stress.
