ER 310 Welding Wire

OVERVIEW OF ER 310 WELDING WIRE

ER 310 Welding Wire is a high-alloy austenitic stainless steel filler metal designed for welding 310 and 310S stainless steels. It offers excellent oxidation resistance, superior strength at elevated temperatures, and outstanding corrosion resistance in severe environments.

This welding wire is widely used in high-temperature and high-corrosion applications, especially where resistance to scaling, heat, and thermal cycling is critical. ER 310 welding wire performs exceptionally well in both continuous and intermittent service at elevated temperatures.
