Duplex Steel UNS S31803 Welded Pipes

MBM Tubes are suppliers of Duplex Steel UNS S31803 Welded Pipes based in Mumbai. We have an inventory where we produce high quality goods for all our customers.

S31803 Welded Pipes have a mixture of properties like weldability, high strength and resistance to stress-corrosion cracking. Low temperature applications also do not cause much harm to these Duplex Steel Welded Pipes. Duplex steel is not completely austenitic nor completely ferritic. This grade is often referred as work horse grade. The main advantage of this steel type is that it combines austenitic steel and ferritic steel properties to give amazing outcomes. We manage our products under high levels of production standards and quality control measures.
