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. Please feel free to contact us if you have any requests. 【Features】 ■ Partial hardening is possible ■ High surface hardness, excellent wear resistance, and fatigue strength are achieved ■ High compressive stress on the surface results in excellent fatigue strength ■ Fine microstructure provides excellent ductility, toughness, and fatigue strength ■ The uneven distribution of carbon and alloying elements before hardening tends to reflect in the hardened structure and properties *For more details, please refer to the PDF document or feel free to contact us.
