The different quench agitation mode of quenching systems used for induction hardening must be considered in the process design stage to ensure optimal results.
Induction heat treating can be performed on a wide range of steels and cast irons. Acceptable hardening responses can be achieved with medium carbon steels (0.35-0.5% carbon) with or without alloying additions . Although steels with higher carbon content can be induction heat treated, they are typically susceptible to increased risk of cracking . Induction hardening processes can also be used in conjunction with thermochemical processes such as carburizing and ferritic nitrocarburizing to obtain even greater enhancement of properties [2,3].
