[Processing Technology] Vacuum Carburizing (Direct Carburizing)

Since there are no grain boundary oxidation or carburization irregularities on the surface layer, it is also possible for the inner surface of the pores! Quality improvement can be expected.

"Vacuum carburizing hardening" is a carburizing hardening method conducted in a vacuum furnace. Acetylene gas supplied into the furnace undergoes thermal decomposition, and the carbon generated penetrates and diffuses from the surface. In addition to the carburizing effect, there is no grain boundary oxidation or carburizing unevenness in the surface layer, making it possible for the inner surfaces of pores as well. Moreover, since it finishes with a bright luster, quality improvement can be expected compared to conventional carburizing hardening. 【Features】 ■ Carburizing hardening method conducted in a vacuum furnace ■ In addition to the carburizing effect, it allows for the inner surfaces of pores due to the absence of grain boundary oxidation and carburizing unevenness in the surface layer ■ Finishes with a bright luster ■ Quality improvement can be expected compared to conventional carburizing hardening ■ JIS processing symbol: HQV *For more details, please refer to the PDF materials or feel free to contact us.

【Processing Technology】Glowing Quenching

Prevents oxidation and decarbonization, and can protect luster! It also leads to a reduction in post-processing such as shot blasting.

"Radiant Hardening" is a hardening method that finishes with the surface maintaining a metallic luster. By processing in a non-oxidizing atmosphere, it prevents oxidation and decarburization, allowing for the protection of the radiant quality. This also leads to a reduction in subsequent processes such as shot blasting. Please feel free to contact us when you need our services. 【Features】 ■ A hardening method that finishes with the surface maintaining a metallic luster ■ Prevents oxidation and decarburization ■ Can protect the radiant quality ■ Leads to a reduction in subsequent processes such as shot blasting ■ JIS processing symbol: HQB *For more details, please refer to the PDF document or feel free to contact us.

[Processing Technology] Carburizing Quenching and Carburizing Nitriding Quenching

It is widely applied to various machine parts, including automotive parts and marine parts!

"Carburizing hardening" is a treatment that allows carbon to penetrate and diffuse from the surface of a metal, hardening only the surface. The surface becomes hard and wear-resistant, while the interior maintains lower hardness, providing high toughness and improved fatigue resistance. "Carburizing nitriding" is a treatment that allows both carbon and nitrogen to penetrate and diffuse into the surface of steel, hardening only the surface layer. This improves wear resistance. 【Features】 ■ Carburizing hardening - The surface becomes hard and wear-resistant - The interior maintains lower hardness, providing high toughness - Fatigue resistance can also be improved ■ Carburizing nitriding - A treatment that hardens only the surface layer - Wear resistance is improved *For more details, please refer to the PDF document or feel free to contact us.

[Processing Technology] Flame Hardening (Frame Hard)

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.
