Description
An electrode wire, copper-covered, with a content of Cr = 1.25% and Mo = 0.5% for semi-automatic welding in the gas shielding C1 (CO2) or mixture shielding M21 (Ar + CO2). Metallurgical properties of wires provide high-quality welds and reliable wire feed in the mechanised welding process. Working temperature of welded joints up to (500°C). IMT CrMo1Si is intended for welding low-alloy steels resistant to creep and for welding high-pressure boilers and pipelines.
