DAIKOFCW 1010

The alloy, characterized by a high percentage of carbides, offers exceptional wear resistance, although this results in reduced impact and corrosion resistance. Due to the increased hardness, there is a tendency to crack during cooling, which can be minimized by carefully controlling preheating, interpass temperature, and post-heating techniques. Even though cobalt-chromium deposits soften slightly at high temperatures, they are generally considered immune to tempering. The welding metal deposited by the ERCoCr-C electrodes and rods is ideal for components like mixers and rotors, where extreme abrasion and limited impacts occur. Additionally, it is also suitable for pump sleeves, rotary seal rings, wear pads, extrusion screws, and bearing sleeves. The inclusion of tungsten improves high-temperature hardness and matrix toughness, ensuring excellent resistance to solid particle and adhesive erosion wear. It maintains a hardness of 43–58 HRC at temperatures up to 760 °C. Preheating to 300 °C and beyond is generally recommended.
