OK Autrod 347Si

OK Autrod 347Si is an austenitic stainless steel filler material for welding of stainless steel alloys of 18Cr/8Ni/Nb and 18Cr/8Ni/Ti types where good general corrosion resistance is required. The alloy is stabilized with Niobium to improve the resistance against intergranular corrosion of the weld metal. The higher silicon content improves the welding properties, such as wetting. Due to the niobium content the alloy is recommended for use at higher temperatures.
