摘要
阐述了我国内燃机用气阀钢的应用现状和性能要求,介绍国内外常用气阀钢的钢号和标准。根据气阀钢的组织特点,将气阀钢分成马氏体气阀钢、奥氏体气阀钢和高温合金三大类,并对马氏体气阀钢、奥氏体气阀钢进行了性能对比。
The application and properties for the valve steel in China was described.The grades and standards of common valve steel in the world were introduced.According to the microstructure of steel grades,the valve steel could be divided into three classes,i.e.martensite valve steel,austenite valve steel and super alloy steel.The properties comparison of valve steels between martensite and austenite structures was reported.
