Flame hardening in electronic science and technology

Flame hardening in electronic science and technology

Highly regarded and widely trusted craftsmanship! Flame hardening by Electronic Science Industry.

Flame hardening in electronic science and industry uses a gas flame as a heat source to rapidly heat the surface of the hardened area for quenching. At first glance, it may seem like a primitive method, but similar to high-frequency heat treatment that utilizes Joule heating, the short heating time prevents decarburization and minimizes surface peeling, which is one of its characteristics. It excels in processing complex shapes and large components, but requires advanced technology for temperature management. To produce industrial products that demand uniformity in small lots with a variety of types and short delivery times, skilled craftsmanship is essential. Our flame hardening has been certified by manufacturers for improving the mechanical properties of automotive parts, aerospace and defense industry components, and main components for observatories, earning us widespread trust. [Features] - Uses a gas flame as a heat source to rapidly heat the surface of the hardened area for quenching. - The short heating time prevents decarburization and minimizes surface peeling. - Collaborates with public research institutions for the "visualization of skilled craftsmanship." *For more details, please refer to the PDF document or feel free to contact us.

N Quench (Nitriding Hardening)

N Quench (Nitriding Hardening)

The finishing skin is good! The processing time is short, and a 20μ curing layer can be obtained in 40 minutes.

"N-Quench (Nitriding Quenching)" is a treatment method that allows nitrogen to penetrate and dissolve in steel within the austenite region of the Fe-N phase diagram, followed by rapid cooling to obtain hard nitrogen martensite. In nitriding quenching, the nitrided layer hardens into nitrogen martensite due to rapid cooling, but the interior does not harden because it is cooled from below the transformation temperature of the Fe-C system. Furthermore, the thermal treatment distortion (dimensional change) is comparable to that of gas soft nitriding. 【Features】 ■ Hardness of HV800 or higher can be achieved even with low carbon steel. ■ The amount of gas used is extremely small, about 1/10 of that used in gas soft nitriding. ■ Processing time is short, with a hardened layer of 20μ obtained in 40 minutes. ■ The finish is good. ■ The treatment is environmentally friendly. *For more details, please refer to the PDF document or feel free to contact us.

N-hard (gas soft nitriding hardening)

N-hard (gas soft nitriding hardening)

A 20μ curing layer can be obtained with a 40-minute treatment! This is a processing method that can reduce operating costs.

"N-Hard (Gas Soft Nitriding)" is a treatment method where gas soft nitriding is performed just above the A1 transformation temperature on the Fe-N phase diagram, followed by rapid cooling to obtain a mixed phase of nitrides and nitrogen martensite. The surface forms an extremely hard layer compared to the nitrided layer, consisting of a mixed phase of nitrides (or carbonitrides) and nitrogen martensite. However, the interior undergoes rapid cooling below the A1 transformation of the Fe-C system, so it does not harden. 【Features】 ■ Thermal treatment distortion (dimensional change) is small, comparable to gas soft nitriding. ■ Hardness of HV800 or higher can be achieved even with low carbon steel, and HV1000 or higher with SK5. ■ Processing time is shorter compared to gas soft nitriding, achieving a hardened layer of 50μm in 90 minutes. ■ Processing time is short, achieving a hardened layer of 20μm in 40 minutes. ■ The finish is good. *For more details, please refer to the PDF document 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.
