Heat resistant steel castings refer to cast parts made of heat resistant steel materials and have good high temperature resistance. Heat resistant steel is a special kind of steel with high heat resistance and corrosion resistance, and can maintain high strength and stability in high temperature environments. Heat resistant steel castings are usually used in equipment and components under high temperature working conditions, such as petrochemical, electric power, metallurgy, aerospace and other fields. These castings can withstand pressure, wear, corrosion and oxidation at high temperatures, ensuring the normal operation and safety performance of the equipment.

Processing technology:

  ● Casting: Heat resistant steel castings are usually produced by methods such as precision casting or sand casting. During the casting process, attention must be paid to controlling the temperature and cooling rate to ensure the quality and performance of the castings.

  ● Heat treatment: Heat treatment is an important step in improving the mechanical properties of heat resistant steel castings. By heating, maintaining and cooling the casting, the internal structure of the material can be adjusted and its hardness, wear resistance and other properties can be improved.

  ● Mechanical processing: Heat resistant steel castings can be processed through turning, milling, drilling and other mechanical processing methods to meet the needs of different usage scenarios. During the machining process, attention must be paid to controlling the cutting speed and depth of cut to prevent problems such as cracks or deformation.

Features:

  ● It maintains high strength and stability in high temperature environments and is not easy to deform or fail.

  ● Resist high temperature oxidation and corrosion, extending service life.

  ● It has good plasticity, is easy to process and manufacture, and can meet the processing needs of various complex shapes.

  ● Easy to weld and can be connected with other metal materials through welding process.

  ● Compared with other high performance metal materials, heat-resistant steel castings are more affordable and can reduce production costs.

Scenes to be used:

  ● Aerospace: Manufacturing key components for aircraft and rockets, such as engines, combustion chambers and tail nozzles. These components need to work in high temperature environments, requiring materials with excellent heat resistance and stability.

  ● Automotive industry: used to manufacture high temperature components such as engines, exhaust pipes, and turbochargers. These parts need to work in high temperature environments for a long time, requiring materials with good oxidation resistance and high temperature strength.

  ● Energy sector: manufacturing core components for equipment such as boilers, nuclear reactors and thermal power plants. These parts need to work in extremely high temperature environments, requiring materials with excellent heat resistance and stability.

  ● Chemical industry: manufacturing reactors, distillation towers, pipelines and other equipment. These equipment need to work in high temperature and corrosive environments, requiring materials with good oxidation resistance and corrosion resistance.
