The comprehensive properties of wheel steel for high speed train with carbon content from 0.4% to 0.7% were studied. As a result of increased carbon content, the abrasion resistance and contact fatigue durability of the test steel is increased, in the mean time, its impact toughness and thermal fatigue resistance is decreased. The test steel with 0.5%C and a small amount of microalloyed element has better comprehensive properties after 880 deg C normalizing and 530 deg C tempering, including better thermal fatigue resistance, higher contact fatigue durability, and proper abrasion resistance Thus the steel is suitable for produce high speed train wheel with higher resistance on fatigue damage such as spalling.
