DAIKOWT 1006

This cobalt-based alloy is widely recognized as the most extensively used type, offering abrasion resistance, along with robust defenses against corrosion, erosion, and thermal shock. It excels in resisting galling, sliding friction, and compression across various temperatures. The alloy's distinctive features include a hypereutectic structure comprising roughly 13% eutectic chromium carbides distributed within a solid solution matrix of cobalt, chromium, and tungsten. It is extensively employed for surfacing valves, valve seats, hot shear blades, punches and dies, ingot tong ends, and equipment utilized in handling hot steel. Noteworthy applications include its use for cat cracker slide valves in the petrochemical industry, as well as across a broad spectrum of sectors such as steel, cement, marine, and power generation. Preheating within the range of 100-300°C, or even higher, along with slow cooling, may be necessary to mitigate the risk of cracking in multi-run deposits and/or highly restrained conditions. The deposits are machinable using carbide tools and can be refined through grinding as needed. Importantly, these alloys remain impervious to allotropic transformation, ensuring that their properties endure even after subsequent heat treatment of the base metal.
