Low Carbon, Buffer-Layer Ready, Excellent Arc with Ferrite Balance
Low carbon, basic-coated stainless electrode with ~15% ferrite for welding dissimilar metals (carbon to stainless), high-temperature steels, and as a buffer layer before hardfacing. Offers smooth fusion, refined bead appearance, and reliable slag release for civil engineering, cladding, and structural repairs.
