Instruction and Application: Ultra-low carbon stainless steel tungsten electrode arc welding wire, with low content of C, S and P, good performance of metal mechanical properties and good corrosion resistance.Suitable for welding of 347 (06Cr18Ni11Nb) type austenitic stainless steel. It can also be used for the surface corrosion resistance of carbon steel or low alloy steel.
