The steel plates for SA302GrC boilers must withstand different pressures and strengths due to the manufactured containers. Generally, the normal pressure is 314MPa or higher, and the working temperature is often between -20°C and 450°C. According to the working conditions and processing requirements of the vessel, the steel plate must have good cold bending and welding performance, good plasticity and toughness, and high temperature short-term strength or long-term strength performance.
A588 grade B heavy plate, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of A588 grade B heavy plate, Chinese grade 45 steel depends on its various properties. A588 grade B heavy plate, Chinese grade 45 steel has certain toughness and plasticity, high strength and good machinability. Good comprehensive mechanical properties of Chinese grade 45 steel can be obtained by quenching and tempering treatment. Chinese grade 45 steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.
Quenching Improve the hardness of A588 grade B heavy plate steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of A588 grade B heavy plate steel and comprehensive mechanical properties.
A588 grade A steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness."When propertly exposed to the atmosphere, A588 Grade A is suitable for many applications in the bare condition. A588 grade B heavy plate, A588 Grade Acould be produced in 200mm in our company.
