文章探讨了影响合结钢40Cr力学性能一次检测合格率的关键因素。引用正交试验结果制订了“常用40Cr钢试样热处理工艺”,通过检测分析一次不合格试样的C％偏析存左的问题和五害元素影响,提出了提高40Cr钢力学性能一次检测合格率的主要途径。
The paper discusses the key factors that affect the pass rate of 40Cr mechanical properties of steel. The results of the orthogonal test were formulated “common 40Cr steel sample heat treatment process” by testing and analysis of a failed sample of C% segregation left and the impact of five pests elements proposed to improve the 40Cr steel mechanical properties of a test pass rate The main way.
