CmCtw CMC-STB description: It is suitable for punch armor welding and repair of forging die under 900C without cooling liquid, especially strengthening for high-temperature black metal cutting blade and armor surfacing for hot radial forging die. In production of hot-work die, it can also be welded on H13 or 5CrNiMo as preliminary protection of enhancing heat resistance and abrasion resistance. Besides, it can also be used on the top of seamless steel tube as well as on rolling wheel, top and guide plate of hollow shaft.
