[Product Description]SangdoTDS has been performing various heat treatments for 20 years, and we design and manufacture heat treatment facilities and processes optimized to the user’s desired materials and demanded characteristics through utilizing development, manufacturing, and quality control technologies that we have accumulated for the last 20 years.We also offer technical transfer consulting including facility maintenance, manufacturing and quality management technology, etc., to help even customers without prior heat treatment related experience to begin manufacturing products stably as soon as possible after introducing facilities.
[Features] Quenching refers to the process of heating metal parts at a high temperature, maintaining their temperature, and letting them cool down immediately in a cooling medium (oil or water).Metal parts are reheated after quenching; this process, which strengthens the metal, is called tempering.The purpose of tempering is to strengthen the internal microstructure of the metal, because the high rigidity obtained through quenching renders the metal brittle before it is reheated. As a result, quenching and tempering are performed as a pair, and thus called quenching and tempering (QT).
OthersIt is commonly used in the mass-production of small products of 5 kg unit weight or less. It requires fewer personnel due to easy operation through automation. Non-oxidizing heat treatment is possible by using CH3OH, RX-GAS, and DX-GAS for ambient gas.
