Definition: Duplex stainless steel consists of austenitic and ferritic two-phase microstructures, with better corrosion resistance and higher mechanical properties than ordinary austenitic stainless steel.
Advantages: It is more resistant to stress corrosion cracking (SCC) than austenitic stainless steel and has approximately twice the strength and safety of standard austenitic steel.
Automotive sector: Duplex stainless steel is used in the automotive industry to manufacture components for cars, buses, trucks and trailers, as well as treatment plants for the automotive industry. Weight loss and safety: Due to its high strength and yield strength, duplex stainless steel helps to reduce the weight of the car while improving safety.
Corrosion resistance: In automotive manufacturing plants, especially in coating lines, duplex stainless steel is used to manufacture conveyor belts to ensure excellent corrosion resistance.
Corrosion resistance: Due to high chromium, nitrogen content and molybdenum, duplex stainless steel provides significant local and uniform resistance to corrosion.
Weldability: Duplex stainless steel has good weldability and can be welded using TIG, MIG and laser hybrid welding technology.
Stress corrosion cracking: Compared to conventional austenitic stainless steel, duplex stainless steel is more resistant to stress corrosion cracking under many conditions.
Lightweight: Duplex stainless steel has twice the tensile strength of conventional austenitic or ferritic stainless steel, making it ideal for weight reduction designs.
Cost effective: Using duplex stainless steel can reduce material and life cycle costs because it has lower nickel and molybdenum content than austenitic stainless steel, which has the same corrosion resistance.
Good toughness: The toughness of duplex stainless steel is much better than that of ferritic steel, but it has not yet reached the excellent level of austenitic steel.
