Duplex Steel UNS S31803 Pipe Fittings / Duplex Steel S32205 Pipe Fittings, which performs better to some extent in robustly oxidizing atmospheres up to 816 Deg Celsius. Duplex Steel UNS S31803 Elbow Pipe Fittings is the superior carbon variant of the alloy, that enables improved creep resistance and for superior strength at temperatures more than 537 Deg Celsius. Duplex Steel UNS S32205 Reducer Pipe Fittings are commonly used in aircraft engine parts, petroleum refineries, power generation, pressure vessels, heat exchangers, welded fabrications and other elevated heat applications. Furthermore, these Duplex Steel UNS S31803 Tee Pipe Fittings is as well hot hard and is therefore often find its application in turbine construction. Duplex Steel UNS S32205 Cross Pipe Fittings is not hardenable in the course of heat treatment, but small parts can be cold work hardened.
