针对重载车轮的损伤特点，研制了一种以C、Si为主要强化元素的铁素体珠光体型车轮新材料，通过C、Si含量的合理配合，使车轮材料具备了高强度并保持了较高的韧性，同时具有合理的相变特性。装车运行试验表明，与目前常用的车轮材料相比，这种车轮材料的抗机械损伤性能和抗热损伤性能得到了较好的协调，更适合重载运输条件。

A new ferritepearlite wheel steel with C and Si as main strengthening elements was developed aiming at the damage characteristics of heavy duty wagon wheel.With rational C and Si contents, the steel has high strength, relatively high toughness and reasonable phase transformation characteristics. Online loading test showed that the new steel has a better balance between antimechanical and antithermal damage properties and is more suitable for heavy duty transportation than conventional wheel steel.
