[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.

Presentation of explanatory materials on "waist reinforcement" that gives toughness to industrial blade steel discs!

Presentation of explanatory materials on "waist reinforcement" that gives toughness to industrial blade steel discs!

This explains the essential "waist adjustment" during the processing of board materials with circular saws and chip saws. It is provided by Tokai Heat Treatment, which adjusts the waist value with machinery to achieve stable quality.

Industrial blades (circular saws and chip saws) are affected by "centrifugal force" and "frictional heat" during use, causing the edges of the blades to expand and resulting in the entire "industrial blade" becoming warped, leading to "bending." To prevent this, the center part is pre-stressed with a hammer to elongate it. This elongation process is called "koshii-re." ★ We are currently offering explanatory materials on "koshii-re"! ★ Tokai Heat Treatment, which specializes in heat treatment processing of materials for industrial blades, has recently produced explanatory materials regarding "koshii-re." [Contents of the materials] - The effects of heat generated in industrial blades - The necessity of "koshii-re" - Introduction to our company *These materials are currently available for download from our company website. We apologize for the inconvenience, but please request "About Koshii-re" from the yellow tab on the right side of the homepage labeled "Download Materials and Catalogs."

Carburizing heat treatment "Carburizing quenching / Carburizing nitriding / Bright quenching"

Carburizing heat treatment "Carburizing quenching / Carburizing nitriding / Bright quenching"

Achieving the desired carburizing curve! Capable of distortion correction for shafts and thin-walled shapes, as well as press tempering.

At the Chuo Yondan Heat Treatment Research Institute, there is a carburizing technology that achieves maximum hardness through post-process shot peening. In "Carburizing Quenching/Carburizing Nitriding/Luminescent Quenching," we pursue the appropriate hardness curve to realize the ideal carburizing quenching. By adding ammonia, the "Carburizing Nitriding Quenching," which performs carburizing and nitriding simultaneously, can achieve hardened layers even on raw materials such as SS400 and SPCC, providing excellent wear resistance. 【Features】 ■ Provides carburizing quenching for racing gears ■ Achieves the desired carburizing curve (total hardened layer depth T0.05 to 3.0) ■ Capable of magnetic particle inspection after quenching ■ Capable of masking to prevent carburizing ■ Capable of distortion correction and press tempering for shafts and thin-walled shapes *For more details, please refer to the PDF materials or feel free to contact us.
