[Metal Heat Treatment Guide] What is Annealing?

[Metal Heat Treatment Guide] What is Annealing?

Introducing "tempering," which increases strength and ductility and is also used as a preliminary treatment for quenching.

"Annealing" is a heat treatment that removes internal stresses caused by processing, restores the structure to a standard state, and refines it. By performing annealing, strength and ductility are increased, making it useful as a preliminary treatment for quenching. Additionally, steel is held in the austenite structure for a sufficient period and then cooled adequately in air. 【What is Annealing】 ■ Removes internal stresses caused by processing ■ Restores the structure to a standard state or refines it ■ Steel is held in the austenite structure for a sufficient period and then adequately cooled in air *For more details, please refer to the PDF document or feel free to contact us.

Low-strain heat treatment method "Nitriding Quenching" *Integrated support from pressing process to assembly.

Low-strain heat treatment method "Nitriding Quenching" *Integrated support from pressing process to assembly.

[Technical Data Publicized in 4 Types] Reduces strain by 50% compared to conventional processing methods! A new heat treatment method that generates zero CO2 emissions as it does not use carbon gas.

Aitec's "Nitriding Quenching" is a surface hardening heat treatment method characterized by "low distortion," which allows nitrogen to infiltrate and diffuse into steel and perform quenching from the austenite state. Distortion is associated not only with quality issues but also with challenges related to polishing labor and costs due to distortion correction. By reducing distortion itself, total cost reduction can be achieved. 【Benefits of Nitriding Quenching】 ■ High surface hardness of HMV800 or more even with SPCC material ■ Lower quenching temperature than carburizing, resulting in low distortion (with examples of 50% reduction in distortion) ■ High resistance to softening ■ Total cost reduction without distortion correction ■ No CO2 emissions (environmental protection) [Aitec's Strength 1: Contract Analysis of Heat Treatment Distortion] We analyze the amount of distortion before and after heat treatment using a 3D scanner, allowing for shape comparison before and after treatment. We also accommodate requests for analysis only. [Aitec's Strength 2: Integrated Production] By providing integrated production of pressing and heat treatment, we can guarantee product dimensions. We offer added value by consolidating suppliers. ~ We are also seeing an increase in requests for prototypes and tests. Please feel free to contact us! ~ *Technical materials can be viewed from [PDF Download].

Salt bath (saline bath) heat treatment

Salt bath (saline bath) heat treatment

【Metal Heat Treatment】Super short delivery time with shipment within 24 hours from reception! We also accommodate small lot hardening starting from just one pin!

**About Salt Baths** A salt solution is created by heating and melting chemicals such as potassium chloride, sodium chloride, and sodium nitrite. This is a quenching method where products are heated in a salt bath quenching tank filled with salt solution and then rapidly cooled with low-temperature salt solution. The salt solution has superior heat transfer compared to gases, allowing heat to be evenly transmitted to the object. Since the salt solution directly contacts the object, it minimizes cooling unevenness during cooling, leading to stabilization of the structure and preventing risks of hardness unevenness, distortion, and cracking. **Our Features** We perform quenching by heating above 800°C in a pit-type carburizing furnace and rapidly cooling in a salt bath at 170°C to 180°C. By rapidly cooling, even materials like S45C, which are difficult to harden, achieve higher hardness compared to oil cooling. Additionally, as mentioned above, this reduces the risks of hardness unevenness, distortion, and cracking. **Materials Suitable for Salt Baths** Carbon steel (S45C, S50C) Carbon tool steel (SK2, SK4, SK5, SK6, SK7) Structural steel (SS material, SCM435) Bearing steel (SUJ2), etc. *For more details, please refer to the PDF or feel free to contact us.*
