摘　　要：对新型内燃机气阀用钢 5 Cr8Si2的各项重要性能及组织进行了与老钢种的对比试验。研究结果表明 :5 Cr8Si2钢具有更优良的加工性能和使用性能 。Some important properties and microstructures of valve steel 5Cr8Si2 for internal combustion engine were studied and compared with that of the old type steel. It has been showed that steel 5Cr8Si2 has better processing and working properties. So it can be used widely to replace the old type steel in our country.
