Duplex stainless steel is a highly resistant grade of Stainless SteelS UNS NO S 31803, which is used in the oil & gas, marine tools, pulp & paper, and food industries. It also has improved resistance to stress corrosion and is resistant to both chloride and sulfide environments. 


Duplex Stainless SteelS UNS NO S 31803, also known as 'Duplex', is used in gas turbine engines. These engines are subjected to extremely high temperatures, and therefore require the highest strength, fatigue life, and high temperature creep resistance. 


Those properties are critical for gas turbine engines, which are used in aircraft and other industrial applications. However, there are other types of Duplex Stainless Steel, including UNS S31803 Round Bar.


Duplex Steel S 32760 Spool Fittings are used in high-temperature environments. They are more corrosion-resistant than traditional austenitic stainless steel. Duplex UNS S31803 Spool Fittings is often used for marine applications. For example, they combine a ferritic and austenitic alloy to increase strength. The material should be forged at a temperature of between 1100 degrees and 1250 degrees and then cooled in still air.


Duplex UNS S31803 Wire is available in coil form and spools. Both are a type of Duplex Steel. These are two-phase stainless steels with a balanced ferrite-austenite ratio. If you need a Duplex Steel Wire in a hurry, CSI is the company to choose. They can ship the product to you or your manufacturing facility anywhere in the world.
