Metal Heat Treatment "Vacuum Heat Treatment"

Metal Heat Treatment "Vacuum Heat Treatment"

Clean working environment! We carry out stainless steel solid solution treatment, vacuum magnetic annealing, and more.

"Vacuum heat treatment" refers to a general term for heat treatment conducted in a vacuum furnace. Unlike in the atmosphere, it does not cause oxidation or decarburization, making it a technology that allows for a highly lustrous finish. It is adopted for the heat treatment of many components and products, typically performed in a vacuum with a pressure of 1 to 10^−3 Pa or in an inert gas atmosphere. Our company maintains a stable and high production capacity from single items to mass production, performing processes such as quenching of various tools and parts, solid solution treatment of stainless steel, and vacuum magnetic annealing. [Features] ■ Reduction of heat treatment distortion through vacuum heating and gas cooling ■ Clean working environment ■ Processing possible with heat cycles and vacuum levels set according to purpose ■ High lustrous finish achievable due to the absence of oxidation and decarburization ■ Stable and high production capacity maintained from single items to mass production *For more details, please refer to the external link page or feel free to contact us.

Metal heat treatment "quenching and tempering"

Metal heat treatment "quenching and tempering"

We respond to various needs with the technology and know-how cultivated in the precision manufacturing area of the Suwa region!

"Quenching" is a process in which steel is heated to a temperature that transforms it into austenite and then rapidly cooled. While quenching increases hardness, it also makes the material brittle and prone to cracking, so tempering is always performed to adjust hardness and add toughness. "Tempering" refers to the process of reheating the material to a temperature lower than that used during quenching, holding it for a certain period, and then gradually cooling it. Our company is equipped with batch-type and continuous-type quenching furnaces, as well as various tempering furnaces, allowing us to meet a wide range of customer needs. [Features] ■ Stable processing enabled by the use of diverse equipment ■ Use of dedicated furnaces for small items prevents product loss ■ Expertise and know-how cultivated in the Suwa region, a hub for precision manufacturing, to meet various needs *For more details, please refer to the external link page or feel free to contact us.

Metal Heat Treatment: Heating Treatment of SUJ2 Round Bars by μ High-Frequency Quenching

Metal Heat Treatment: Heating Treatment of SUJ2 Round Bars by μ High-Frequency Quenching

The original characteristics of high-frequency quenching treatment can also be achieved with small diameter round bars such as φ3.

When high-frequency hardening is applied to φ3SUJ2 (bearing steel), it is very difficult to achieve the characteristics of high-frequency hardening, where the surface is hard and the core remains tough, using existing equipment. This is because the small diameter allows heat to affect the core, resulting in full hardening. However, with the 'μ high-frequency hardening treatment' developed by Marushin Heat Treatment Industry, it is possible to achieve the original characteristics of high-frequency hardening, where the surface is hard and the core remains tough, even for small diameter round bars like φ3. 【Test Piece Measurement Results】 ○ Hardness Comparison → Oil-quenched product: Hardened to the core → μ high-frequency hardened: Forms a hard layer of about 0.5mm, core remains tough ○ Bending Test Results → Oil-quenched: Fractured at 500N → μ high-frequency product: No fracture ○ Product Characteristics (※ Runout at product acceptance: approximately 0.02-0.04mm) → Oil-quenched product: Runout of about 0.3-0.4mm → μ high-frequency product: Runout of about 0.15-0.3mm For more details, please contact us or download the catalog.
