Gautam Tubes are offering the superior quality of SUPER DUPLEX STEEL PIPES & TUBES to the global industrialists based upon the needs and demands. We as a manufacturer, supplier, stockiest and exporter are providing duplex steel pipes/tubes to the clients at various specifications that vary in types, standards, ends, and lengths, etc. also it is made available to the clients at custom-built specifications according to the prerequisites of the buyers.
Duplex stainless steel is called as austenitic-ferritic or duplex grade due to the metallurgical structure that is consisting of 2-phases that is ferrite and austenitic in almost equal proportions. They are utilized because of their good mechanical properties in the as-welded condition and also because of their resistant to corrosion property especially to stress corrosion cracking.
Super duplex an EN 1.4410 grade like Super Duplex S32750 Pipes & Tubes, Super Duplex S32760 Pipes & Tubes is also called as the hyper duplex grade is developed for meeting the demands of oil and gas and chemical industries.
It offers excellent corrosion resistance and strength but is difficult to process because the high carbon content of N, W, Cr, Ni, Mo promotes the inter-metallic phase formations that drastically reduces steel impact resistance.
