Selecting the range and depth of the hardened layer after quenching is relatively easy! Introducing heat treatment using fire.

"Flame (Flame Hardening)" is a quenching method that has been used for a long time as one of the surface hardening methods for steel or cast iron. It improves wear resistance, enhances mechanical properties, and allows for partial hardening. Due to rapid heating and rapid cooling treatment, there is little oxidation, decarburization, or deformation, and it is not restricted by the shape or dimensions of the workpiece. Please feel free to contact us when you need our services. 【Features】 ■ No restrictions on the shape or dimensions of the workpiece ■ Localized heating is possible ■ Setup for hardening is easy and work can be done quickly ■ Selection of the hardened layer range and depth is relatively easy ■ Little oxidation, decarburization, or deformation due to rapid heating and cooling treatment *For more details, please refer to the related links or feel free to contact us.

basic information

【Other Features】 ■ The hardness of the hardened layer gradually decreases, so there is no risk of peeling. ■ Alloy steel for machine structures can be surface hardened even with air cooling, so there is no concern about cracking. ■ No jigs or coils are required, as in high-frequency quenching. *For more details, please refer to the related links or feel free to contact us.
