Duplex Steel S31803 Valves

Being one of the reputed manufacturers, the industry use high end modern tools in their fabrication process in order to enhance the efficiency of the products. Furthermore, their products are constantly upgraded according to the latest market trends or customers demands made.

Know about the grade: The S31803 or Duplex SS 2205 is one of the most widely used SS grade in the industries. This ferritic austenitic SS grades finds its best applications in extreme corrosive environment and thus offers high resistance to corrosion, great strength and excellent pitting resistance to chloride environment. The S31803 has the best chemical composition which further enhances its mechanical properties. This Duplex grade tends to offer the best resistance to corrosion but is not generally suitable in temperature ranging above 300-400 Degree C due to the reason of precipitation of micro constituents and others.

Talking about its especial property, the grade offers outstanding resistance to local corrosion that includes mainly pitting, inter granular and also the crevice. The Duplex Steel UNS s31803 valves can be used in extreme situations as the grade can be solution treated but it cannot be hardened using any kind of thermal treatment.

Quality material tests: The highly trained professionals of the Champ Steels conducts relevant material tests on Duplex Steel UNS s31803 valves which helps them to ensure the better quality and efficiency of the grade. All of these tests are performed before finally delivering it to the clients. Tests such as mechanical tests, bend tests, micro and macro tests, pitting resistance tests, positive material identifications tests and flaring tests are some of the essential tests performed.
