Detailed Information

Duplex Steel S31803 Welded Pipes Manufacturer in the United States.

Duplex steel is not completely austenitic nor completely ferritic. This grade is often referred to as workhorse grade. The main advantage of this steel type is that it combines austenitic steel and ferritic steel properties to give amazing outcomes. Duplex Steel is a cost-effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking. Duplex UNS S31803 Seamless Pipes and Tubes can be utilized in marine environments, brackish water, bleaching operations, closed-loop water systems, and some food processing applications. Duplex Steel UNS S31803 Pipes are also used in various industries like chemical processing, transport and storage, Oil and Gas exploration and processing equipment, Marine and other high chloride environments, Pulp and paper digesters, liquor tanks, and paper machines. As a recognized Stockist of Duplex Steel UNS S31803 Pipes in the USA, these ASME SA790 Duplex S31803 Pipes are available in customized sizes, shapes, dimensions, national & international standards, etc.

We at Amardeep Steel Centre manufacture these UNS S31803 Pipes & Tubes using superior quality raw materials and advanced technology in accordance to the globally accepted quality standards and various industrial requirements. 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 UNS S31803 Tubes have features like high resistance to chloride stress corrosion cracking, resistance to chloride pitting and crevice corrosion, good general corrosion resistance, good sulfide stress corrosion resistance, high strength, good weldability, and workability, etc. ASTM A790 Duplex Steel S31803 Welded Pipes as well raise the vulnerability of stainless steels to stress corrosion cracking.
