1. Petrochemicals: Duplex stainless steel has a wide range of applications. Due to its excellent corrosion resistance and good strength, it can be used to manufacture petrochemical equipment, pressure vessels, pipelines, etc. Among these devices, duplex stainless steel can effectively resist the corrosion of various chemicals, ensuring the service life and safety of the equipment;

2. Oil and gas: In the oil and gas industry, duplex stainless steel plays a crucial role in helping to resist harsh conditions. This is because its strength, resistance to pitting and crevice corrosion are superior to standard austenitic stainless steel, and the pitting equivalent value (PREN) of duplex stainless steel is usually higher than 40;

3. Construction industry: Duplex stainless steel continues to play an important role in bridge construction. Bridges are used in corrosive and saline environments, while requiring high bearing strength;

4. Chemical equipment: Duplex stainless steel has excellent corrosion resistance and wear resistance, and can be used to make chemical storage tanks, heat exchangers, tower tanks, pipelines and other equipment;

5. Ocean engineering: high requirements are placed on the corrosion resistance and strength of materials. Duplex stainless steel has been widely used in the field of ocean engineering. It can be used to manufacture facilities such as ocean platforms, ships, and subsea pipelines. Among these facilities, duplex stainless steel can effectively resist the corrosion of seawater, ensuring the service life and safety of the facilities.

6. Automotive industry: Duplex stainless steel are used in the automotive industry for exhaust systems and other applications that require high temperature and corrosion resistance.
