1. Duplex structure: Duplex stainless steel is composed of two crystal structures: austenite and ferrite. This structure gives it high strength and corrosion resistance. The austenite phase provides good plasticity and toughness, while the ferrite phase increases the material's hardness and strength.
2. Good corrosion resistance: Duplex stainless steel shows good corrosion resistance in corrosive environments. Its ferrite phase contains elements such as chromium and molybdenum, which can effectively resist the erosion of corrosive media, while the austenite phase provides better corrosion resistance.
3. Good welding performance: Duplex stainless steel has good welding performance and can be processed by various welding methods. This is because its dual-phase structure effectively controls the heat-affected zone during the welding process, reducing welding deformation and cracks.
4. Excellent mechanical properties: Duplex stainless steel has high strength and hardness while maintaining a certain degree of plasticity and toughness. This gives it excellent performance when withstanding high stress and impact loads and is widely used in various engineering fields.
5. Good wear resistance: Duplex stainless steel has good wear resistance due to the presence of its ferrite phase. This makes it excellent in some applications where resistance to wear and abrasion is required.
