Classification and Types of Heat Treatment

Classification and Types of Heat Treatment

There are four types of heat treatment: quenching, tempering, annealing, and normalizing.

This is the basic form of heat treatment, with quenching being its representative. Annealing is performed to soften steel, while tempering is done to make it tougher. In addition to these, there are heat treatments such as carburizing quenching and high-frequency quenching that harden the surface, but these are merely applications of the basic heat treatments. With the development of the machinery industry, needs have diversified, and in response, heat treatment has become complex and varied, but the fundamental forms are undoubtedly the four: quenching, tempering, annealing, and normalizing. ★ For inquiries by phone, please contact us here: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 *When calling, please mention "Ipros was seen."

[Case Study of Solution through IH Heat Treatment] Out of tolerance due to distortion.

[Case Study of Solution through IH Heat Treatment] Out of tolerance due to distortion.

Our company is engaged in efforts and development to minimize distortion in various components.

There are various factors that cause dimensional changes, but broadly speaking, they can be categorized into two main types: "dimensional changes due to the release of residual stress" and "dimensional changes due to structural transformation (phase change)." Minimizing distortion in precision parts is extremely important, as forcing correction can lead to the risk of cracking, and the strength gained from hardening will undoubtedly decrease. Therefore, our company is engaged in efforts and development to minimize distortion in various components. In particular, when changing processes from atmospheric treatment to high-frequency hardening, significant effects can be expected. If you have concerns about distortion, please feel free to consult us. *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 us on "Ipros." Operating hours: Monday to Friday, from 9 AM to 5 PM.

[Case Study on Solving Heat Treatment Issues 1] A must-see for those struggling with hardness!

[Case Study on Solving Heat Treatment Issues 1] A must-see for those struggling with hardness!

Not enough hardness? If the material's structure is not appropriate, no matter how much you harden it, the hardness will not increase!

No matter how much ferrite is heated and cooled, its hardness does not increase. Especially in the case of casting, a minimum pearlite rate of 70% or more is necessary for stable quenching. The material can affect the quality of heat treatment. Particularly with castings, there tends to be significant variation between batches, so caution is required. At Fuji Electronics, we have various inspection equipment in-house, including X-ray metal material analyzers, allowing for the rapid identification of root causes. *For more details, please refer to the PDF materials or feel free to contact us.

Metal heat treatment "Carburizing quenching treatment"

Metal heat treatment "Carburizing quenching treatment"

Stable high production capacity! It is applied to various machine parts, including automotive components.

"Carburizing hardening treatment" is a heat treatment method that hardens the surface of steel by allowing carbon to permeate it. The hardness of steel after hardening is influenced by the carbon content; therefore, steel with a low carbon content increases in hardness through carburizing hardening. Our company is equipped with fully automatic carburizing furnaces and continuous gas carburizing furnaces, providing stable and high production capacity for thin, small, large, single items, and mass production. [Features] - Utilizing the characteristics of each facility, we can accommodate very shallow carburizing for thin and small items. - Carburizing nitriding treatment is also performed depending on the type of steel. *For more details, please refer to the external link page or feel free to contact us.
