The pulley material is HT250. In China, HT250 is a grade of grey cast iron. HT stands for the initials of the Chinese pinyin “huitie” (grey cast iron), and the number 250 refers to its tensile strength of 250 MPa. In brief, HT250 is grey cast iron featuring excellent castability, vibration damping performance, wear resistance and machinability. ● Properties and Application Range: It is pearlitic grey cast iron with favorable strength, wear resistance and heat resistance, good vibration damping and superior casting performance. Artificial aging treatment is required. It can be applied to pump housings, vessels, towers, flanges, stuffing box bodies and glands, carbonization towers and chemical towers that demand rigidity and certain corrosion resistance. It is also used for machine tool beds, columns, cylinders, gears and components requiring surface hardening. We also provide custom special-shaped parts. Our factory is equipped with sophisticated processing equipment, strong technical capacity, advanced production technology and sound quality management system. We deliver premium-quality products at reasonable prices with large supply capacity. Customers from all over the world are welcome to contact us for business negotiations.
