The production process of heat-treated medium and heavy plates includes heating, soaking, cooling, and post-treatment of the plates, covering energy consumption, material consumption, waste management, and environmental emissions required during the production process.
Process Description
Heat-treated heavy plate is a type of steel plate that undergoes a precision heat treatment process to improve its mechanical and physical properties. The heat treatment process includes steps such as heating, soaking, and cooling, which are designed to alter the microstructure of the steel, thereby enhancing its strength, toughness, hardness, and wear resistance. 304 stainless steel heat-treated medium-to-heavy plate is a type of stainless steel plate whose performance has been optimized through these processes, resulting in an end product with exceptional comprehensive properties. The chemical composition of this material primarily consists of approximately 18% chromium and 8% nickel, with low carbon content. The high chromium content provides 304 stainless steel with superior corrosion resistance by forming a stable passive layer in various environments, effectively resisting chemical attack. The addition of nickel enhances its overall structural stability, further boosts corrosion resistance, and ensures excellent ductility and toughness. Heat treatment process, particularly annealing, optimizes the lattice structure of 304 stainless steel, increasing its hardness and strength while maintaining favorable workability. This process also helps eliminate residual stresses, improving performance during welding and forming operations.

Technology comment
Heat treatment of medium and heavy plates is a critical process aimed at improving the mechanical properties and physical characteristics of steel plates by controlling heating and cooling. This process includes several main steps: normalizing, quenching, and tempering. The plate is heated to an appropriate temperature, typically above the critical point of the steel, and then uniformly cooled either in a furnace or in air. Subsequently, the steel plate is reheated to a higher temperature and then rapidly cooled (or sometimes slowly cooled), usually in water or oil. Finally, to eliminate the brittleness induced by quenching, the steel plate is reheated to a lower temperature and then cooled again.
