induction hardening steel

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。

Typical materials include ductile iron castings or steel forgings. Most crankshafts require some form of heat treating including case hardening, nitriding and induction harden.

特殊的材料包括球墨铸铁和钢煅品，大部分机轴经过热处理，表面硬化、渗氮和感应淬火。

Induction surface hardening of the workpiece material is usually carbon steel.

感应加热表面淬火的工件材料一般为中碳钢。
