What are the parameters of the wear resistance of cemented carbides in addition to their hardness?
Even the best knives in the world, if not1, reasonable processing parameters;2 、 proper installation and use;3 、 timely maintenanceAnd so on, it will turn into a scrap of iron in a short time.
The bending strength of YG20 can reach 2500, which is suitable for making stamping dies. The bending strength of YG15 and JK13 can reach 2550, and the bending strength of JK15 can reach 2600, but the wear resistance is lower. The flexural strength of JK1 is 2500, and it has good wear resistance.
The wear resistance of cemented carbide is related to the proportion of titanium carbide and cobalt carbide contained in it. It contains more titanium carbide, less cobalt content, higher hardness and better wear resistance. But brittleness also increases, easy to break the edge, so it is suitable for finishing.
