ASME SA789 Super Duplex Steel S32750 Welded Tube is the combination of both austenitic steel and ferritic steel. It has good oxidation resistance and acid resistance and can work at 540 ~ 875℃ for a long time. And the welded tube has features of high strength, good wearability, and workability. It also has a low rate of thermal expansion, superior resistance to chloride pitting and crevice corrosion. So this ASME SA789 Super Duplex Steel S32750 Welded Tube is widely used for conveying water, gas, air, oil, and hot water or steam, and so on. This tube is subject to strict quality inspection before shipment, including both destructive and non-destructive inspection in the factory.
