APPLICATION:
Cobalt 1 Electrode: This alloy has a higher carbide content (19%) than those made using either Cobalt 6 or Cobalt 12 electrodes. The composition is such that the microstructure contains primary hypereutectic carbides, which gives the alloy higher wear resistance accompanied by reductions in impact and corrosion resistance. The higher hardness also means a greater tendency to stress crack during cooling. Continuous Cast Alloys minimizes this cracking tendency by closely monitoring preheating, interpass temperature, and post heating techniques. While the CoCr deposits soften at elevated temperatures, they normally are considered immune to tempering. Cobalt #1 is used to build up mixer rotors and items that encounter severe abrasion and low impact.
Class: ECoCr-
