This process adjusts hardness and toughness for the purpose of improving mechanical properties.
Non-oxidation quenching and tempering, also known as thermal refining, is a thermal treatment that adjusts hardness and toughness while obtaining the specified strength by performing tempering at a relatively high temperature after quenching. Carburizing is a thermal treatment suitable for tapping screws and drill screws, whereas tempering is mainly for automotive and construction bolts.
- ・ This processing is mainly suitable for automotive and construction bolts and parts.
- ・ A prescribed strength, hardness, and toughness can be obtained.
- ・ Highly controlled atmospheric gas prevents surface oxidation and significant decarburization.
