ESAB OK Tigrod 347Si 2.0mm x 1000 5kg welding wire for stainless steel

An uncoated, corrosion-resistant chromium-nickel wire rod for welding austenitic chromium-nickel alloys with 18% Cr and 8% Ni.

OK Tigrod 347Si offers good overall resistance to corrosion. The alloy is stabilized with niobium to improve resistance to intergranular corrosion of the weld metal. The higher silicon content improves the technical welding characteristics. Due to stabilization with niobium, this alloy is recommended for use at higher temperatures.
