Development of an As-Cast Austenite-Bainite Wear-Resistant Steel

Pan Chuan

Abstract

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.
