310S Stainless Steel Welding Rod Wire
ER310 SUS310 welding rod/wire is a high-quality austenitic stainless steel filler material designed for welding 310 stainless steel and similar high-temperature alloys. This product provides excellent high-temperature corrosion resistance, thermal stability, and mechanical strength, making it ideal for furnaces, heat exchangers, chemical processing equipment, and high-temperature piping systems. The 310S variant features low-carbon content to reduce sensitization and intergranular corrosion during welding.
