Duplex 2507 Sheet
Duplex 2507 Sheet is a high-performance stainless steel alloy known for its exceptional strength and corrosion resistance. This super duplex grade combines the benefits of austenitic and ferritic stainless steels, offering enhanced durability in harsh environments. Characterized by a balanced microstructure of approximately 50% ferrite and 50% austenite, it delivers superior mechanical properties and excellent resistance to stress corrosion cracking, pitting, and crevice corrosion.
Manufactured as flat rolled sheets, these plates are available in various thicknesses and finishes to meet diverse industrial requirements. The material typically exhibits a tensile strength of around 850 MPa and a yield strength of approximately 550 MPa, making it suitable for applications demanding high strength-to-weight ratios. Additionally, its excellent weldability and formability simplify fabrication processes without compromising performance.
Widely employed across sectors such as chemical processing, oil and gas, marine engineering, and desalination plants, this alloy sheet is ideal for components exposed to aggressive chloride environments. Its resistance to localized corrosion makes it particularly valuable for heat exchangers, pressure vessels, storage tanks, and piping systems where longevity and reliability are critical. The duplex structure also ensures improved fatigue resistance under cyclic loading conditions.
Export-ready and compliant with international standards such as ASTM A240 and EN 10088, these sheets are supplied with comprehensive certification and traceability documentation. This facilitates seamless integration into global supply chains and meets stringent quality assurance requirements. Packaging and handling are optimized to protect the material during transit, ensuring it arrives in pristine condition for immediate use.

Manufacturing Process & Heat Treatment of Duplex 2507 Sheet
Annealing
Annealing of Duplex 2507 sheets is performed to relieve internal stresses and improve ductility. The sheets are heated to a temperature range of 1000-1100°C, held for a specific duration, and then cooled in air. This process helps in refining the microstructure and enhancing the mechanical properties of the material.
Forging
Forging of Duplex 2507 involves the mechanical deformation of the material at elevated temperatures. The process starts with heating the steel to approximately 1100-1200°C, followed by shaping through various forging techniques. This enhances the strength and toughness of the final product by imparting a fine-grained structure.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020-1100 | Oil or Water | To increase hardness and strength |
| Tempering | 500-600 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 300-500 | Air | To relieve residual stresses |
The manufacturing and heat treatment processes for Duplex 2507 sheets are crucial in achieving the desired mechanical properties and ensuring performance in challenging environments. Proper control of these processes results in superior corrosion resistance and strength.
