Gas carburizing and carburizing nitriding

Carbonitriding contributes to the improvement of strength characteristics of various machine steel parts, including automotive components!

We would like to introduce our heat treatment process of "gas carburizing and carburizing nitriding." "Gas carburizing" involves heating steel materials to approximately 900 to 940°C in an atmosphere of endothermic gas primarily composed of CO, N2, and H2, with the addition of enriching gases such as butane and propane, allowing carbon to penetrate the surface of the material. This is followed by quenching to harden the material. On the other hand, "carburizing nitriding" is a process where carbon and nitrogen are simultaneously penetrated into the surface of steel at a lower temperature of approximately 800 to 880°C compared to standard gas carburizing, followed by quenching to harden the material. 【Characteristics of Gas Carburizing】 ■ Applicable steel types: Low carbon alloy steels such as skin-hardening steels (SCM, SCr, SNCM, etc.) ■ Achieves a thick surface hardening layer while ensuring high toughness internally ■ Depth of hardening layer and surface hardness can be adjusted according to requirements ■ Several types of quenching oils can be selected based on internal hardness and component shape ■ The surface has a smooth finish with a light gray color (in the case of low-temperature tempering) ■ Improves wear resistance, impact strength, and fatigue strength *For more details, please download the PDF or feel free to contact us.
