对一种新型合金工具钢的渗氮特性进行了初步研究。
Nitrided characteristics of a new kind alloys tool steel are investigated.
渗氮在钢表面获得远远超出正常标准的硬度。其硬度范围为900到1,100布氏硬度，这远高于普通表面硬化所获得的硬度。
Nitriding develops extreme hardness in the surface of steel. This hardness ranges from 900 to 1,100 Brinell, which is considerably higher than that obtained by ordinary case hardening.
建议对这种钢在渗氮前先机加工和热处理，因为渗氮后没有剥落并不需要更多的加工。
It is recommended that these steels be machined and heat-treated before nitriding, because there is no scale or further work necessary after this process.
