The main spare parts of Excavator and Bulldozer undercarriage is track link, which is made of 40Mn2 steel or 35MnB steel bars and plays the role of connecting the track shoes and transmitting power. For the Bulldozer or Excavator which working in a serious environment, 35MnBH steel is used widely to maximize the life span of each component and minimize the operation cost. The physical property is as follows.
