Salt Bath / Oustenber

Salt Bath / Oustenber

Same-day response is possible! Since we can perform both heat treatment and surface treatment, we can handle everything consistently with a single request.

Our company offers processing using salt baths and austempering. The advantage of salt baths is their flexibility. Unlike large equipment that requires waiting for a batch to be completed, the ease of adjustment allows for shorter delivery times. Austempering is a type of quenching and tempering that results in less deformation and distortion compared to conventional quenching and tempering. It also has greater toughness and higher impact resistance, so even at the same hardness, the strength is completely different from that of conventional quenching and tempering. 【Features】 ■ Same-day response available ■ Salt bath: Achieves short delivery times with ease of adjustment ■ Salt bath: Can suppress bending and deformation ■ Austempering: Processing with less deformation and distortion compared to conventional quenching and tempering ■ Austempering: Greater toughness and higher impact resistance *For more details, please refer to the PDF document or feel free to contact us.

LODIC (Logic) processing

LODIC (Logic) processing

Lower distortion than carburizing nitriding, higher strength than soft nitriding! Ultra-low temperature carburizing nitriding hardening treatment.

LODIQ (Low Distortion Quenching) is our unique surface heat treatment method that fills the gap between "soft nitriding" and "carburizing hardening (carburizing nitriding)." It addresses issues such as "normal soft nitriding does not provide sufficient strength" and "normal carburizing (carburizing nitriding) results in excessive thermal distortion." Additionally, while maintaining the low distortion characteristics of LODIQ, we have achieved an increase in the strength of alloy steel with "LODIQ-AS," and we also offer "LODIQ-N," which allows for arbitrary changes in the compound layer composition to enable strengthening according to specific objectives. **Characteristics of LODIQ-AS** - Significantly reduces heating distortion and hardening distortion through ultra-low temperature treatment. - Increases resistance to temper softening of the re-surface, improving anti-seizing and anti-pitting properties. - Enhances effective hardened layer depth, internal hardness, and fatigue strength for low carbon steel LODIQ. - Enables the omission of finishing processes due to the suppression of abnormal grain boundary oxidation layers and the low distortion effect. *For more details, please download the PDF or feel free to contact us.*

High-frequency heat treatment

High-frequency heat treatment

Partially harden. Optimal heat treatment with advanced technology.

Only the parts that require wear resistance can be hardened through surface hardening using electromagnetic induction. Due to rapid heating and rapid cooling, there is minimal oxidation and decarburization on the surface, and no thermal deformation occurs, resulting in excellent wear resistance. By changing the frequency, the depth of hardening can be adjusted, allowing for processing in a short time. Because very fast heating occurs, the know-how of skilled craftsmen is required. ● Heating coils suitable for the product shape are necessary. ● Detailed prior discussions will be conducted to perform heat treatment suitable for the material. ● Surface hardening allows the interior to remain as the original material while maintaining high toughness.

Vacuum heat treatment

Vacuum heat treatment

It is suitable for heat treatment of materials such as Ti, Inconel, and SUS thin plates, where oxidation prevention is difficult!

We would like to introduce our "Vacuum Heat Treatment." We adopt a method where all processes from heating to cooling are conducted in a heating chamber, preventing oxidation during cooling. Since vacuum is inert to metals, it is used as an ideal atmosphere, resulting in a good surface condition with excellent luster that requires little to no finishing. Additionally, the vacuum heat treatment heating is conducted solely by radiant heat, resulting in a very gentle temperature rise. This leads to a small temperature difference between the surface and the center of the treated item, allowing for uniform expansion and contraction, and enabling heat treatment with minimal distortion. 【Features】 - A vacuum pressure corresponding to 1×10−1 Pa retains 1 ppm of impurity gas. - Conducted solely by radiant heat. - The surface maintains its luster, and deformation is minimal, allowing for significant reduction in post-treatment processing. - No quenching oil is used, and there is no intrusion of oil into the chamber or vacuum furnace. *For more details, please refer to the PDF document or feel free to contact us.

Technical Introduction: "Carburizing and Nitriding Heat Treatment"

Technical Introduction: "Carburizing and Nitriding Heat Treatment"

We have a wealth of accumulated technology in the field of processing techniques for reducing material costs, which is one of our strengths.

Carburizing and nitriding treatment refers to the process of simultaneously or continuously performing carburizing and nitriding. Generally, for materials with poor hardenability, such as low-carbon low-alloy steel, carburizing is conducted while adding ammonia gas or similar substances to achieve both carburizing and nitriding, aiming to improve the hardenability of the material at lower transformation temperatures. By performing nitriding, it becomes possible to effectively introduce hardness into materials that do not harden with carburizing alone. The quality characteristics obtained from carburizing and nitriding treatment include improved wear resistance and fatigue strength, similar to carburizing, as well as enhanced softening resistance. Recently, carburizing and nitriding treatment has also been applied to alloy steel or bearing steel for the purpose of improving mechanical properties. ● For more details, please contact us.
