KOVET-ER309L is a stainless steel welding wire (Cr22Ni12). It has excellent temperature and corrosion resistance. It has stable welding arc and can be used in all welding position. It can be used in the welding of stainless steel of the same type, and the dissimilar materials welding between carbon steel and stainless steel. This electrode is commonly used for welding of clad surface of stainless clad steel or for under-laying on mild steel for hard surfacing.
