High-frequency hardening

Partial hardening is possible! The structure is fine, resulting in excellent ductility, toughness, and fatigue strength.

"High-frequency quenching" is a process that involves rapidly heating the surface layer, allowing carbon to dissolve into the base material, maintaining a diffusion holding time of about 1 second, and then spraying a quenching agent to perform surface hardening. This treatment is applied to quenching steels containing more than 0.25% carbon, but generally, low alloy steels such as carbon steels with about 0.4 to 0.5% carbon or Cr-Mo steels with less than 0.4% carbon are commonly used.
