The Properties and Application of Low Alloy Bainitic Cast Steel
In the paper, the composition, structures and properties of low alloy bainitic cast steel is introduced, its bainitic cast steel has high strength, toughness and wear-resistance and low alloy bainitic cast steel contains suitable Si, Mn and Cr and trace amount of V, Ti, B and rare earth(RE)has high hardness and toughness in air quenching. jaw plate in jaw crusher and ball mill liner made from low alloy bainitic cast steel have long service life, its service life is 1.5～3.0 times longer than high manganese steel's. The wear amount of low alloy bainitic cast steel ball is 70%～90% lower than that of common forging steel ball and low Chromium cast iron boll, nearing that of high Chromium cast iron ball. While using in the pipe transporting mine powder, the service of low alloy bainitic cast steel is 3～4 times longer than that of 16Mn. Low alloy bainitic cast steel has simple production process, small valuable alloy adding mount and low production cost, using in the metal mine, the equipment production rate is evidently increased, the processing cost of mine powder is decreased.
