The Weld Star ER310 Stainless Steel TIG Wire is a fully austenitic filler wire engineered for TIG (GTAW) welding of stainless steels of similar composition and certain dissimilar applications. With high chromium and nickel content, this wire exhibits excellent resistance to oxidation and scaling at elevated temperatures, making it ideal for industrial applications where heat resistance is essential.
This versatile TIG wire is commonly used in the fabrication and repair of industrial furnaces, annealing chambers, boiler parts, heat exchangers and other heat-resistant assemblies. It also performs well when welding similar stainless grades or for overlay work on carbon and mild steels requiring enhanced oxidation tolerance.
