AWS ER-347 Stainless Steel Welding Wire
Description:
The main component of the wire is 19Cx-11Ni - Nb, which is stainless steel Mig welding wire and can be welded in all positions.
Because adding Nb on the basis of sUS308 can effectively improve corrosion resistance, especially Improve the resistance to grain boundary corrosion. Excellent welding performance - smooth wire feeding, stable arc, beautiful shape and little spatter.
Application:
It is often used in food machinery, medical devices, pressure vessels, petrochemical and other occasions, such as 07Cr19Ni11Ti (SUS 321), 07Cx18Ni1INb (SUS 347).
