摘要
结合我国资源特点 ,以Si、Mn为主加元素 ,研制了中碳低合金奥氏体 贝氏体耐磨钢。其显微组织为铸态下奥氏体 贝氏体为主的机械混合物。该钢具有高硬度、高韧性 (40～ 5 8HRC、ak≥ 15～ 4 5J/cm2 )和良好的抗磨性能 ,可在铸态下使用 ,无需热处理 ,能替代常用的ZGMn13钢。
According to the natural resources in our country, a king of new medium carbon, high wear resistance steel containing silicon and manganese as alloying elements has been developed. One of the characteristics of this steel is a mixed structure of austenite and bainite under as cast condition. It has high hardness, high toughness (40～58HRC? a k≥15～45J/cm 2) excellent resistance to abrasive wear. It can be used under as cast condition without heat treatment. This austenite bainite wear resistanct steel is an ideal new material for replacement of tranditonal austenitic high manganeses steel.
