Selectarc HRT63

This tubular electrode is filled with metal powders (chromium and niobium carbides) and is specifically designed for hardfacing applications. It produces a deposit characterized by exceptional hardness and abrasion resistance, combined with moderate impact resistance. The deposit is composed of complex carbides of chromium and niobium within an austenitic matrix, providing excellent resistance to mineral abrasion and impact due to the fine presence of niobium carbides. The hardened deposit offers resistance up to 300°C. It’s recommended to use with low current and requires finishing by grinding, and doubling the current is possible with a second electrode to increase the deposition rate.

This electrode is primarily used for hardfacing a variety of metals, including C steels, grey cast iron, alloyed steels, and tool steels. It’s ideal for applications in civil engineering, cement industries, agriculture (specifically for press screws, mixing blades, jar teeth and blades, scrapers, crushing hammers, sieving gates, and excavator teeth). The recommended welding procedure involves maintaining an arc length of 2 to 5mm, weaving with the electrodes, and holding the electrode perpendicularly to the surface, limiting the number of layers to 2 or 3 to ensure optimal results.
