An electrode wire, copper-covered, with a content of Cr = 9.0% and Mo = 1.0% for semi-automatic welding in the gas shielding (Ar + CO₂) or (Ar + CO₂+ O₂ ). Metallurgical properties of wires provide high-quality welds and reliable wire feed in the mechanised welding process. Working temperature of welded joints up to (650°C). IMT CrMo91 is intended for welding P91/T91-type creep-resistant steels and steels working at hight temperatures.
