Product type
Super Duplex Stainless Steel is a high-performance alloy known for its exceptional strength and corrosion resistance. It combines the properties of both austenitic and ferritic stainless steels, offering a unique microstructure that enhances its durability in harsh environments. This material is typically composed of iron, chromium, nickel, molybdenum, and nitrogen, making it suitable for a variety of challenging applications.
| Corrosion resistance | Excellent resistance to pitting and crevice corrosion |
| Tensile strength | Typically ranges from 620 to 800 MPa |
| Yield strength | Usually between 450 to 650 MPa |
| Ductility | Elongation of around 25% in 50 mm |
| Temperature range | Effective in temperatures up to 300°C |
When selecting Super Duplex Stainless Steel, consider the specific grades available, as they can vary in composition and properties. Be sure to specify the desired mechanical properties, such as tensile and yield strength, and any relevant certifications for your application. Additionally, indicate the required quantities and any specific tolerances needed for your project to ensure optimal performance.
