ROYAL PRIME 308L is a flux cored stainless steel wire designed for welding 304L and equivalent stainless steels. The low carbon content provides excellent resistance to intergranular corrosion. It delivers a stable arc, smooth bead appearance, and easy slag removal in all positions (with proper parameters).
