Heat-resistant steel thick-walled steel pipe is a commonly used high-temperature equipment material in the industrial field, and its quality and performance are crucial for the stable operation and safety of the equipment. As a common heat-resistant steel material, ZG35CR24Ni7Si2N has good high-temperature performance and mechanical strength, and is widely used in the manufacture of high-temperature equipment such as centrifugal cast pipes and furnace tubes.
The chemical composition of ZG35Cr24Ni7Si2N mainly includes elements such as chromium, nickel, silicon and nitrogen. These elements play different roles in steel, which together guarantee excellent high-temperature and mechanical properties. Among them, chromium can improve the oxidation resistance and corrosion resistance of steel, nickel can enhance the toughness and plasticity of steel, silicon can help improve the strength and hardness of steel, and the addition of nitrogen can refine the grain of steel and improve its mechanical properties.
In the manufacturing process, ZG35Cr24Ni7Si2N adopts the centrifugal casting process, and by controlling the pouring temperature, cooling rate and other process parameters, the molten metal is filled and solidified into a casting with the desired shape and performance under the action of centrifugal force. This process can make the casting have a dense grain structure and uniform composition distribution, which further improves its mechanical properties and service life.
As a high-quality heat-resistant steel material, ZG35Cr24Ni7Si2N has excellent high-temperature performance and mechanical properties through reasonable chemical composition design and application of centrifugal casting process, which can meet the needs of various high-temperature equipment.
