Duplex Steel UNS S31803 filler wire is a welding consumable specifically designed for joining duplex stainless steel materials. Duplex stainless steels contain a balanced microstructure of approximately 50% ferrite and 50% austenite, which gives them a unique combination of strength and corrosion resistance.
The UNS S31803 grade is one of the most commonly used duplex stainless steels due to its excellent resistance to chloride stress corrosion cracking, pitting, and crevice corrosion. Filler wires made from this alloy are widely used in welding applications where high mechanical strength and corrosion resistance are essential.
These filler wires are particularly suitable for welding duplex stainless steel pipes, pressure vessels, tanks, heat exchangers, and structural components used in aggressive environments.
Key Features of Duplex Steel UNS S31803 Filler Wire
