We Piyush Steel are the manufacturer, supplier, and exporter of the commendable quality of Duplex Steel UNS S31803 Tubes are designed from ferrritic and austenitic stainless steel alloy that includes molybdenum, chromium and nitrogen content. This structure of these tubes is neither fully austenitic nor purely ferrritic. Thus these ensure both the features of austenitic and ferrritic stainless steel alloy. The tubes possess superior high strength and resistance to corrosion in elevated temperatures. The addition of content ensures superior resistance to crevice and chloride pitting corrosion. Therefore these ranges of tubes are suitable in marine environments and brackish water. In addition to the tubes enables excellent resistance to intergranular corrosion and oxidation. These grades of tubes are also resistant to chloride stress corrosion cracking at a temperature range of 150 degree C. These grades of tubes often perform well in those circumstances that are caused by premature failure of other grades. The tubes exhibit superior ductility and mechanical strength along with moderate corrosion resistance in various environments. The tubes are annealed at the temperature range of 1020 -1070 degree C and then water quenched. Furthermore, the hot working is performed in the temperature range of 954-1149 degree C. In addition to the hot working of these tubes is further performed under room temperature is recommended if it is possible. The tubes are machined either with high speed or carbide tooling. In order to attain excellent weldability various welding methods such as TIG, MIG, and SMAW are recommended.
