DAIKOFCW 1010

The high percentage of carbides gives the alloy higher wear resistance accompanied by reductions in the impact and corrosion resistance. The higher hardness also means a greater tendency to check during cooling. The checking tendency may be minimized by closely monitoring preheating, interpass temperature, and postheating techniques. While the cobalt-chromium deposits soften somewhat at elevated temperatures, they normally are considered immune to tempering. Weld metal deposited by ERCoCr-C electrodes and rods is used to build-up items such as mixers, rotors, or wherever harsh abrasion and low impact are encountered. Suitable also for applications such as pump sleeves, rotary seal rings, wear pads, expeller screws and bearing sleeves. The addition of tungsten enhances high temperature hardness and matrix toughness for excellent adhesive and solid particle erosion wear resistance. It retains its hardness, 43–58 HRC, at temperatures up to 760°C. Preheat at 300°C and over in general.
