Duplex stainless steel combines the advantages of ferrite and austenite. Chromium, nitrogen, of high molybdenum content, these steels have good corrosion resistance. Duplex helps organizations achieve high strength and high resistance to stress corrosion cracking performance. Duplex stainless steel also has good weldability.

Excellent corrosion resistance, high resistance to stress corrosion cracking and corrosion fatigue properties

High mechanical strength, good wear resistance and fatigue resistance

Low thermal expansion

Duplex stainless steel is a special alloy material that combines the microstructures of austenite and ferrite for excellent strength and corrosion resistance, making it an indispensable material for many industrial sectors.

The strength of duplex stainless steel is one of its outstanding features. The austenitic structure can provide the material with high hardness and high tensile strength, while the ferrite structure gives the material good toughness. By reasonably controlling the ratio of austenite and ferrite, duplex stainless steel achieves a perfect balance of strength and toughness, which enables it to show excellent performance in high-strength engineering.

Another important advantage of duplex stainless steel is its excellent corrosion resistance. Stainless steel itself has a certain degree of corrosion resistance, and duplex stainless steel further improves its corrosion resistance on this basis. It can effectively resist oxidation, corrosion and erosion in acidic environments, making it widely used in fields with corrosive environments such as the chemical, petroleum and marine industries.

It is worth mentioning that duplex stainless steel is also widely used in the field of medical devices. It is compatible with internal tissues and fluids and does not cause allergies or reactions. It is ideally suited for the manufacture of surgical instruments, implants and other medical devices. Moreover, its corrosion resistance ensures the long-term service life of medical devices.

Overall, duplex stainless steel is ideal for many industrial sectors due to its excellent strength and corrosion resistance. Its wide range of applications in engineering, chemical, petroleum, and marine fields, as well as its unique value in the medical device field, make duplex stainless steel occupy an important position in material science.
