harden ability

The influence of the chemical compositions and metallurgical quality of this steel on its mechanical properties are analyzed , and the effect of the metallurgical quality on the harden ability is discussed .

就该钢种的化学成分和冶金质量对材料力学性能的影响、冶金质量对淬透性的影响等进行了分析讨论。

The authors consider that there were black microstructures in the carbonitriding , because appetency between alloy elements and oxygen in the steel was greater than that between matrix metal and oxygen , which caused inner oxidation and decrease in harden ability .

文章认为碳氮共渗渗层出现黑色组织，是因为钢中合金元素与氧的亲和力比基体金属大，引起内氧化，导致淬透性下降造成的。

This article commented on the draft of standard for the specified harden ability steel for gear wheel and the contrast and analysis between the same standard in domestic and foreign .

叙述了保证淬透性齿轮用钢标准制定及国内外同类标准对比分析。
