目前大部分工厂的履带板均用高錳鋼鑄造,这种履带板的耐磨性:当在砂土地工作时,由于沒有冲击作用而未能硬化,这时履带板在磨料磨損的情况下的寿命,在-54型拖拉机上为1000小时,在-60型拖拉机上則仅为800小时。为此,阿尔泰拖拉机工厂为代用高錳鋼,曾对20 1.5TP的低碳低合金結构鋼进行了研究工作。 At present most of the factory track shoes are made of high manganese steel, the wear resistance of the track shoes: When working in the sand, because there is no impact and not harden, then the track shoe in the case of abrasive wear Life expectancy is 1,000 hours on the -54 tractor and 800 hours on the -60 tractor. To this end, the Altai tractor factory as a substitute for high manganese steel, had 20 1.5TP of low-carbon low-alloy structural steel research work.
