Rexton Steel & Alloys owned a position of leading manufacturer and supplier of Duplex Steel UNS S31803 Sheets amongst our clients. Duplex Steel UNS S31803 Plates are used in Food processing equipment, Oil field piping and heat exchangers, Flue gas desulfurization equipment, and more. It has lower thermal expansion and higher heat conductivity than austenitic stainless steels. Duplex Steel UNS S31803 Coils are magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless. They are also used in Cargo tanks for ships and trucks, Biofuels plants, and more. A mixture of nitric acid and fluoric acid is used in pickling. Our product is as well commonly used in gas turbine blades, seals and in many other applications. We also offer these products in customized specifications.
These Duplex Steel S31803 Sheets has improved localized corrosion resistance than Stainless Steel 316L and Stainless Steel 317L, and the steel are functional in the industrial fields such as chemical plant, seawater pump, seawater desalination plant, etc. Our Duplex Steel S32205 Sheets are generally used in Oil and Gas Industries: such as in Pipe, Vessels, Pumps, Valves, Wellhead Machinery, Subsea Machinery, Heat Exchangers, Separators, and so on. These Duplex Steel S31803 Plates resists sulfide chloride and stress corrosion atmospheres. Meanwhile, these Duplex Steel S32205 Plates are as well being offered in different sizes and shapes to our customers.
