Wires and rods for semi-automatic welding and hardfacing in the gas mixture shielding Ar + CO2 (MAG) and argon Ar (TIG). Weld deposit resistant to intergranular corrosion and corrosion in liquid media up to 350°C, oxidizing acids and reducing acids at low temperatures. Intended for austenitic stainless steels with low carbon content. Also used for unstabilized and stabilized with Nb and Ti corrosion-resistant CrNi steels. Increased silicon content to improve weldability.
