GW50——以碳化钨为硬质相、以工具合金钢为粘结剂的钢结硬质合金,是一种具有高硬度、高耐磨性,并有足够韧性的新材料,它还具有可锻、可焊、可切削和可热处理的良好的工艺性能。在国内它首先用于轴承行业钢球冷墩模具上,与原来的模具材料 GCr15或 Cr12相比,寿命提高了几倍以至几十倍,取得了可喜的成绩,它所具有的制造工艺简单的特点,更适合中小厂的加工条件,从而受到欢迎。寻找高耐磨性的刀具材料,提高竖井钻机 GW50 - a tungsten carbide carbide with tungsten carbide as hard phase and tool alloy steel as binder, is a new material with high hardness, high wear resistance and toughness. Forging, solderable, machinable and heat treatable good process properties. In the country, it is first used in bearing ball cold pier mold, compared with the original mold material GCr15 or Cr12, life expectancy increased several times or even several times, has made gratifying achievements, it has a simple manufacturing process Features, more suitable for small and medium-sized factory processing conditions, which are welcome. Look for tool materials with high wear resistance and improve shaft drilling rigs
