XM-19 (Nitronic 50) Round Bars
14.30mm - 152.40mm
XM-19 (Nitronic 50) Round Bars, with diameters ranging from 14.30mm to 152.40mm, are a highly corrosion-resistant alloy known for their excellent mechanical properties. Composed of 19-21% chromium, 13-17% nickel, and 2-3% molybdenum, XM-19 offers superior strength and resistance to wear and corrosion, particularly in harsh environments such as seawater, acidic conditions, and high temperatures. These round bars are widely used in industries like marine, chemical processing, food processing, petrochemical, and aerospace for applications such as shafts, valves, pumps, and structural components. Their durability and resistance to pitting, crevice corrosion, and stress corrosion cracking make them an ideal material for critical applications that demand reliability and longevity.
XM-19 (Nitronic 50) Round Bars available in diameters ranging from 14.30mm - 152.40mm.
