XM-19 Stainless Steel Round Bar Supply, Nitronic 50 Rods in Stock

XM-19 stainless steel round bar is a highly machinable and weldable, nitrogen-strengthened austenitic stainless steel. It offers excellent resistance to sulfide stress cracking in air, comparable to Nitronic 50 stainless steel bar. The machinability of XM-19 is on par with 316 or 317 alloys. Its yield strength is twice that of 316 stainless steel, with similar corrosion resistance. Even after extreme forming, XM-19 stainless steel remains non-magnetic. However, its resilience will be higher than that of other austenitic stainless steels. For increased hardness, cold working is recommended. Due to its high tendency to work harden, stress relief annealing should be performed on the workpiece after forming.

Nitronic 50 Round Bar Applications

Corrosion resistance and mechanical strength are combined for use in ship hardware, pump shafts, petrochemicals, pulp and paper, food processing, and the oil industry. Due to its resistance to sulfur stress cracking, it is also suitable for "downhole" applications.
