Duplex S31803 Round Bars
UNS S31803 Round Bar, DIN 1.4462 Rods
We are Manufacturer, Supplier & Exporter of UNS S31803 Duplex steel Bars. We deliver products that are retain their utility in all environments of use. Duplex 2205 Bars have a distinguished content of 22% Chromium, 3% Molybdenum and about 5-6% Nickel and are austenitic-ferritic stainless steels. Duplex Steel Bars are tough and more ductile in comparison to other austenitic grades. We export, manufacture, supply, and store Duplex Steel UNS S31803 Round Bars to clients all over the world at competitive prices. Duplex Steel UNS S31803 Bars offer significantly higher ductility and toughness than ferritic grades, but they fall short of the exceptional properties of austenitic grades.
Duplex Steel UNS S31803 Bars, Wires and Rods are well-known for their endurance and quality. Duplex Steel UNS S31803 Bars are annealed at 1020-1070 degrees Celsius (1868-1958 degrees Fahrenheit) and then water quenched. Duplex Steel UNS S31803 Rods are widely used in welded pipe, tubular components, chemical processing, transportation, and storage, among other applications.
