Heat Resistant Steel Castings

Heat-resistant steel castings are cast parts that can maintain stable performance in high-temperature environments. Heat-resistant steel castings are usually used in mechanical equipment under high-temperature conditions, such as petrochemical, electric power, metallurgy and other industries. These parts need to have high temperature resistance, corrosion resistance, oxidation resistance, wear resistance and other properties to ensure the normal operation and life of the equipment.
The material of heat-resistant steel castings usually uses high alloy steel, such as alloy steel with elements such as chromium, molybdenum, nickel, and titanium. These alloys can maintain good strength and hardness at high temperatures, while also being resistant to corrosion and oxidation. During the casting process, special smelting and pouring processes are usually used to ensure the uniformity and density of the casting.
The design and manufacture of heat-resistant steel castings need to take into account issues such as thermal expansion, thermal stress and thermal fatigue in high-temperature environments. Therefore, parameters such as the thermal expansion coefficient, thermal conductivity, and heat capacity of the material need to be fully considered during the design process to ensure the stable performance of the parts at high temperatures. At the same time, appropriate heat treatment processes need to be adopted during the manufacturing process to improve the strength and hardness of the parts and reduce the accumulation of internal stress.
Heat-resistant steel castings have a wide range of applications, including grates, furnaces, burners, furnace doors, grates, furnace linings, grate plates, etc. These parts are subjected to extremely high temperatures and pressures in high-temperature environments, and therefore require high heat resistance and corrosion resistance to ensure the normal operation and safety of the equipment.
