The aging treatment of equivalent sb480 steel steel plate: in order to eliminate the size and shape changes of precision measuring tools or molds and parts in long-term use, the workpiece is often reheated to 100℃ -150 ℃ and maintained for 5-20 hours before finishing at low temperature after tempering. This equivalent sb480 steel process is called aging to stabilize the quality of precision parts.It is particularly important to aging steel members under low temperature or dynamic loading conditions to eliminate residual stress and stabilize steel structure and size.
Just as equivalent sb480 steel, the boiler steel plate also has strict control of chemical composition for the material, especially harmful elements such as phosphorus and sulfur, and residual elements such as chromium, nickel, and copper; during smelting, good deoxidation and removal of non-metallic inclusions should be carried out to ensure good quality, plasticity and toughness. The organizational structure requires uniformity, and the grain size is controlled within a certain range; there are also strict requirements for surface quality and internal defects. In addition, the boiler steel plate mechanical properties at room temperature and high temperature must be guaranteed.
The annual sales volume of steel product is over 300,000 tons, and the sales volume has increased year by year. The business scope covers the Southeast Asia, Eastern Europe, Middle East, Africa, North America, and South America. Client services are mainly in the petrochemical, wind power, shipbuilding, steel structure, machinery manufacturing, and construction industries.
