Synthetic electrode for difficult-to-weld steels
Product description
High-yield (160%), rutile-coated synthetic electrode for hardfacing and joining high-strength steels to each other and to stainless steels. Also recommended as an undercoat before hardfacing and for welding galvanized sheet metal.
High resistance to cracking. Very smooth melting, very little spatter, self-detachable slag.
