Description：
A super-low carbon Cr22Ni12Mo2 stainless steel electrode ,the carbon content of its deposit metal is ≤0.04%. With excellent operation properties and pores resistance, the proper Mo element improves corrosion and crack resistance. Used to weld similar composition super low carbon stainless steels and dissimilar steel structures.
