Generally used in quenched and tempered state, can also carry on the carbonitriding and high-frequency surface hardening.

一般在调质状态下使用，还可以进行碳氮共渗和高频表面淬火处理。

Grinding hardening, the technology of hardening steel piece surface with grinding heat instead of high or medium frequency induction hardening heat, can integrate grinding surface hardening.

磨削强化处理技术是利用磨削热替代高、中频感应淬火热源对钢件表层进行强化处理，将磨削加工与表面强化合为一体。

The backwashof low frequency, high compressive strength, no powder, no hardening, high activity and large specific surface area, good regeneration effect.

反洗频率低，抗压强度高，不粉化、不板结，比表面积大，活性高，再生效果好。
