In the production process of the claw hammer manufacturer, if it is damaged, it needs to be tempered to ensure the quality of the claw hammer.
Heat the quenched cast wear-resistant masonry hammer to the critical point, keep it at an appropriate temperature for a certain period of time, and then cool it in a manner that meets the requirements to complete the entire operation. The relevant details must be controlled. In the tempering control of the claw hammer, high temperature tempering can be used. The structure obtained by high temperature tempering of the masonry hammer is tempered sorbite. The heat treatment combining quenching and high temperature tempering is customarily called quenching and tempering treatment. The purpose is Obtain comprehensive mechanical properties with good strength, hardness, plasticity and toughness.
The purpose of tempering at medium temperature is to obtain high yield strength, elastic limit and high toughness, which is mainly used for the treatment of various hot work molds. Through tempering, the hammer head has higher hardness and wear resistance, and is less brittle and low in cost.
