Research on Organization and Performance of High Carbon Forging Bainite Wear-resistant Steel

摘要

According to the phenomenon of the grinding ball wide application and low life, put forward on the basis of high carbon wear resistant steel and then optimized composition, adopted the forging and the isothermal quenching process to improve the organization and performance so as to improve the service life of the grinding ball in this paper. Founding a set of comprehensive mechanical properties chemical composition and heat treatment process through the analysis and discussion of experimental results. Compared with the steel forging experiments, the average hardness of experiment steel is increased by 1 HRC and impact toughness increased by more than 7 J/cm~2.
