These different specifications cover the different uns s31803 f51 Rods for various high corrosive, high temperature and high pressure applications. The bars are also used to produce other materials such as pipes, fasteners, fittings and flanges.

The ASTM A276 F51 Duplex Round Bar has 43ksi minimum yield strength and 105ksi minimum tensile strength. The material is made up of 21% chromium, 4.5% nickel, carbon, manganese, phosphorus, sulfur, silicon, molybdenum and nitrogen in the composition. This composition allows the Duplex Steel UNS S31803 Bars to have high performance under elevated temperature for long time.
