Product Description
309S Stainless Steel Welding Rod Wire
ER309 SUS309 for High Temperature Equipment Chemical Processing Piping Corrosion Resistant
Product Overview
309 / 309S stainless steel welding rod/wire (also known as ER309, ER309S, SUS309, SUS309S, WNR 1.4845, 1.4837, SS309) is a high-quality austenitic stainless steel filler material designed for welding 309 stainless steel and similar high-temperature alloys.
It provides excellent corrosion resistance, thermal stability, and mechanical strength, making it ideal for furnaces, heat exchangers, chemical processing equipment, and high-temperature piping systems.
309S is the low-carbon variant, reducing sensitization and intergranular corrosion during welding.
