We would like to introduce our "Statute of Limitations Hardening Treatment." This treatment is performed to harden materials by finely precipitating carbides and other substances that were dissolved through solid solution treatment. Our company owns 2t and 5t batch furnaces as well as 8t and 12t cart furnaces. We can provide efficient responses with suitable treatments tailored to the target products. [Case Overview] ■ Purpose of Treatment: To finely precipitate and harden the dissolved carbides and other substances ■ Equipment Owned - 2t batch furnace, 5t batch furnace - 8t cart furnace, 12t cart furnace *For more details, please feel free to contact us.

We would like to introduce our "quenching and tempering" process. Quenching is a treatment performed to harden steel or increase its strength. Steel that has undergone quenching has low toughness, so tempering is performed to increase toughness and reduce hardness. We own 2-ton and 5-ton batch furnaces as well as continuous furnaces for bar steel, allowing us to provide efficient and cost-minimum responses tailored to the target products. 【Case Overview】 ■ Purpose of quenching: Hardening or increasing the strength of steel ■ Purpose of tempering: Increasing toughness and reducing hardness, aiming for a specified hardness ■ Equipment owned: 2-ton batch furnace, 5-ton batch furnace, continuous furnace for bar steel *For more details, please feel free to contact us.
