Why do we perform tempering?
Enhance durability against stretching and twisting! Introducing five key points of tempering.
Generally, bolts with a medium strength or higher, specifically those classified as 8.8 or above, are hardened to make the steel harder. However, if left hardened, they become hard but brittle and prone to breaking, meaning they lack toughness. Therefore, it is necessary to reheat the steel immediately after hardening to enhance its toughness. This toughness is referred to as "toughness," and by increasing toughness, the durability against stretching and twisting is improved. This process is called "tempering." *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*
