How seamless pressed bend products increase stiffness
1. Quenching and tempering treatment: The heat treatment method of high temperature tempering after quenching is called quenching and tempering treatment. High temperature tempering refers to tempering between 500-650 °C. Quenching and tempering can adjust the properties and materials of steel to a great extent. Its strength, plasticity and toughness are all good, and it has good comprehensive mechanical properties.
2. Aging treatment: In order to eliminate the change in size and shape of precision measuring tools or molds and parts during long-term use, the workpiece is often reheated to 100- 150℃, keep it for 5-20 hours, this kind of treatment to stabilize the quality of precision parts is called aging. It is particularly important to age steel components under low temperature or dynamic load conditions to eliminate residual stress and stabilize the structure and size of hot-pressed bent products.
Annealing of hot-pressed bent products: hot-pressed pressed bend products are heated to a certain temperature and kept for a period of time, and then slowly cooled, which is called annealing. Annealing of hot-pressed bent products is a heat treatment method in which the steel is heated to a temperature where phase transformation or partial transformation occurs, and then slowly cooled after heat preservation. The purpose of annealing is to eliminate structural defects, improve the organization, homogenize the composition and refine the grains, improve the mechanical properties of hot-pressed bent products, and reduce residual stress; at the same time, it can reduce hardness, improve plasticity and toughness, and improve machinability. . Therefore, annealing is not only to eliminate and improve the structural defects and internal stress left by the previous process, but also to prepare for the subsequent process. Therefore, annealing belongs to the heat treatment of semi-finished products, also known as pre-heat treatment.
