Duplex UNS S31803 Seamless Pipe, ASTM A790 Duplex Steel UNS S31803 Pipe, Werkstoff Nr. 1.4462 Duplex Pipe Material Supplier in Mumbai, India
Duplex Steel S31803 pipes have ferritic and austenitic alloy properties, which are above the usual stainless steel pipes like 316 and 316L in terms of overall performance and these are enhanced in terms of resistance to various corrosions. These pipes are specifically designed for the purpose and applications where resistance to corrosion is mandatory. This grade of pipes has high workability in adverse environmental conditions and also performs well in aqueous environments. All the duplex S31803 stainless steel pipes are heat treated under specified temperature and doused conditions. While the chemical composition of this grade of pipes is similar to other austenitic grade of stainless steel pipes .

While this duplex grade has a high content of chromium, nickel, and molybdenum which specifically works wonders in halide containing conditions like seawater environments. It is made to perform under high pressure applications and protect the metal from oxidation and stress-related corrosion. The chromium or chrome acts like skin to the base metal protecting it against various crevice corrosions and pitting. It also helps prevent the metal from oxidation and acidic conditions. Though it can be used under specified temperature only, or it might get subject to embrittlement.
This grade of duplex pipes are fabricated in seamless and welded forms for different usages, but seamless pipes of this duplex S31803 grades has huge demanded in commercial markets due to its high performance compared to welded ones. With a higher yield strength and even higher tensile strength which is usually couple of times higher than the regular stainless steel pipes. While the mechanical properties play huge part in the overall performance of these pipes.
All ASTM A790 Duplex UNS S31803 Pipes are marked as follows: Standard, Grade, OD, Thickness, Length, Heat No. (Or according to the customer’s request.)
