High-frequency hardening

High-frequency hardening

Rapid heating and cooling create significant compressive residual stress, enhancing fatigue strength! Introducing heat treatment that does not use fire.

"High-frequency hardening" utilizes high-frequency induction heating to rapidly heat the surface of the workpiece to the hardening temperature, followed by rapid cooling, creating a hardened layer on the surface that improves wear resistance and enhances mechanical properties. Localized heating allows for relatively easy selection of the depth of the hardened layer based on frequency. Direct heating results in good thermal efficiency and shorter working times. Please feel free to contact us when you need our services. 【Features】 ■ Good thermal efficiency and shorter working time due to direct heating ■ Localized heating allows for relatively easy selection of hardened layer depth based on frequency ■ Rapid heating and cooling processes result in minimal oxidation, decarburization, and deformation ■ Rapid heating and cooling generate significant compressive residual stress, improving fatigue strength ■ High surface hardness provides excellent wear resistance ■ Standardization and automation of work processes are easy *For more details, please refer to the related links or feel free to contact us.

High-frequency hardening

High-frequency hardening

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.

"Partial high-strength steel material" high-frequency hardening

"Partial high-strength steel material" high-frequency hardening

This is a steel material that achieves multiple strengths with a single bar of steel. High-frequency quenching allows for only the areas that require high strength and high durability to be treated with high strength.

In conventional heat treatment using furnaces, it was difficult to apply heat to only the necessary parts of the steel material, as heat was applied to the entire steel. However, by utilizing high-frequency induction heating (IH) to selectively high-frequency quench only a portion of the steel (enhancing strength and durability), multiple strengths have been achieved with a single steel rod. By placing high-strength sections in areas where the integrity of structures and components must be ensured, and low-strength sections in other areas, damage control and reduction of materials are possible. Using this technology and product, we have started selling high-strength rebar placed in column and beam joints that contribute to damage control of structures, reduction of rebar quantity, improved workability, and comfortable living spaces, named "Double Stark®." *In 2018, we received the "Super" Monozukuri Parts Award and the Lifestyle-Related Parts Award.

Why heat treatment is necessary・1

Why heat treatment is necessary・1

In the current automotive industry, where miniaturization and weight reduction of components are required, hardening is an indispensable technology!

We will introduce why heat treatment is necessary and the benefits of quenching. First, one benefit is that quenching allows for the miniaturization and weight reduction of parts. Even small components can achieve strength equivalent to larger parts by increasing their strength through heat treatment, enabling miniaturization and weight reduction. The second benefit is the reduction of material costs. By applying quenching, it is possible to obtain strength equivalent to that of expensive materials even when using common materials. 【Features】 - Enables miniaturization and weight reduction of parts - Achieves strength equivalent to larger parts when strength is increased through heat treatment - An indispensable technology in the current automotive industry, where miniaturization and weight reduction are required - Reduces material costs - Achieves strength equivalent to expensive materials even when using common materials *For more details, please refer to the PDF document or feel free to contact us.

Why heat treatment is necessary - 2

Why heat treatment is necessary - 2

Improving cutting performance, fatigue strength, and wear resistance! Introducing the purpose of heat treatment.

We will introduce the reasons why heat treatment is necessary and the purpose of quenching. The first reason is improved sharpness. By applying quenching only to the cutting edge, the strength of the cutting edge increases. Next, there is an improvement in fatigue strength. In today's demand for lightweight components and longer product lifespans, this fatigue strength is being emphasized. Finally, there is an enhancement in wear resistance. By applying high-frequency quenching to harden the surface, we can prevent wear on components and improve wear resistance. 【Objectives】 ■ Improved sharpness ■ Improved fatigue strength ■ Enhanced wear resistance *For more details, please refer to the PDF document or feel free to contact us. ★ For inquiries by phone, please call: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 *When calling, please mention that you saw this on "Ipros." Operating hours: Monday to Friday, from 9 AM to 5 PM.
