Characteristics of special steel
Special steel has the following characteristics:
1. high strength: the strength of special steel far exceeds that of ordinary steel, and it can withstand greater force and pressure.
2. Corrosion resistance: A variety of alloying elements are added to special steel, which makes it have excellent corrosion resistance and can be used for a long time in harsh environment.
3. Good plasticity: Special steel has good plasticity and can be formed by heat treatment and cold working.
4. Excellent wear resistance: Special steel has high hardness and good wear resistance, and is suitable for manufacturing parts that need wear resistance.
Application field of special steel
Special steel is widely used in various fields, and several main application fields will be introduced below.
astrospace
Special steel plays an important role in the aerospace field. Aeroengine, aircraft structure, missile, etc. Special steel with high strength, high temperature resistance and corrosion resistance is needed. The use of special steel can improve the safety and reliability of aircraft.
automobile making
Special steel is also widely used in automobile manufacturing. Automobile engine, chassis and body structure need special steel with high strength and corrosion resistance. The use of special steel can improve the safety and energy saving of automobiles.
Energy equipment
The application of special steel in the field of energy equipment is also very important. Nuclear power plants, thermal power plants and other energy equipment need to use special steel with high temperature resistance, high pressure and corrosion resistance. The use of special steel can improve the working efficiency and safety of energy equipment.
Machinery manufacturing
Special steel is also widely used in the field of machinery manufacturing. Construction machinery, metallurgical equipment and mining equipment all need to use special steel with high strength and high wear resistance. The use of special steel can improve the service life and work efficiency of mechanical equipment.
Operation steps of special steel
The processing and use of special steel products need to go through the following steps:
1. Selection of raw materials: according to the specific application requirements, select the appropriate special steel materials.
2. Material preparation: cut and forge the selected special steel material to meet the specific size and shape requirements.
3. Heat treatment: heat treatment of special steel, including annealing, quenching, tempering and other processes to improve its strength and corrosion resistance.
4. Machining: turning, milling and drilling special steel according to specific application requirements. To meet the precise size and shape requirements.
5. Surface treatment: The special steel is polished and sprayed to improve its appearance and corrosion resistance.
6. Testing and quality control: analyze and test the mechanical properties and chemical composition of special steel to ensure its quality meets the standard requirements.
