Partial hardening of small parts! It is possible to have a hard surface with high wear resistance and a tough core!
"Flame hardening" is a process that involves heating the surface of steel with a high-temperature flame, followed by quenching to harden the surface layer. Using a torch, the steel is heated partially and then rapidly cooled. This process allows for a hard surface layer with high wear resistance and a tough core, resulting in significant residual compressive stress on the surface, which improves fatigue strength. It is suitable for partial hardening of small items (approximately Φ30 or smaller). 【Features】 ■ A process that heats the surface of steel with a high-temperature flame and then hardens the surface layer. ■ Capable of producing a hard surface layer with high wear resistance and a tough core. ■ The generation of significant residual compressive stress on the surface improves fatigue strength. ■ Suitable for partial hardening of small items (approximately Φ30 or smaller). ■ JIS processing symbol: HQF *For more details, please refer to the PDF document or feel free to contact us.
