NEW TYPE META BAINITIC CARBURIZING STEEL AND ITS APPLICATION

Cheng Ju-qiang, HE Zi-qiang

Abstract

Carburization characteristics and wear behavior of new type meta bainitic steel were studied.The result shows that meta bainitic steel has good carburization properties,especially,the excellent air cooling hardenability.The wear resistance of carburized layer reaches that of 18Cr2Ni4WA steel.The wear mechanism of two body abrasion is mainly micro cutting,three body abrasion is mainly strain controlled fatigue.In addition,its application to heavy drill bar is introduced.
