Blue Demon ER347 Stainless Steel TIG Welding Rods
Blue Demon ER347 Stainless Steel TIG Welding Rod is a stainless steel welding wire used in joining types 321 and 347 grades of stainless steel. The addition of columbium to this alloy reduces the possibility of chromium carbide precipitation and consequent intergranular corrosion.
