Super Duplex 2507 Flanges
Super Duplex 2507 Flanges are engineered from a high-performance duplex stainless steel alloy known for its exceptional corrosion resistance and mechanical strength. This material combines a balanced microstructure of austenite and ferrite, providing superior resistance to chloride stress corrosion cracking and pitting. These flanges are commonly used as critical components in piping systems, serving as the connection points that join pipes, valves, pumps, and other equipment securely under high pressure and demanding conditions.
Manufactured to meet rigorous industry standards such as ASTM A182 and ASME B16.5, these flanges are available in various types including weld neck, slip-on, blind, and threaded configurations. Their chemical composition typically includes approximately 25% chromium, 7% nickel, and 3% molybdenum, which contribute to enhanced durability in aggressive environments. The mechanical properties of this alloy ensure high tensile strength and excellent toughness, making the flanges ideal for applications in oil and gas, chemical processing, and marine industries.
Due to their robust corrosion resistance and strength, these components are widely utilized in offshore platforms, desalination plants, and petrochemical facilities where exposure to seawater, acids, and other corrosive agents is common. Their ability to withstand extreme temperatures and pressures without compromising structural integrity makes them indispensable in critical process lines and high-stress environments.
From an export perspective, these flanges are produced with strict quality control protocols, including non-destructive testing and material traceability, ensuring compliance with international standards. Packaging is designed to protect the flanges during transit, with options for wooden crates or steel pallets to accommodate long-distance shipping. This readiness facilitates seamless integration into global supply chains, supporting industrial buyers who require reliable, high-quality components for their projects worldwide.

Manufacturing Process & Heat Treatment of Super Duplex 2507 Flanges
Annealing
Annealing of Super Duplex 2507 flanges is performed to relieve internal stresses and improve ductility. This process typically involves heating the material to a temperature of approximately 1020-1100°C, followed by controlled cooling. The annealing process enhances the corrosion resistance and overall mechanical properties of the flanges.
Forging
The forging of Super Duplex 2507 flanges is conducted at elevated temperatures, generally between 1000-1200°C. This hot working process enhances the mechanical properties of the material by refining the grain structure and ensuring uniformity. The forged flanges are then allowed to cool gradually to room temperature.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1050-1100 | Water or Oil | To increase hardness and strength |
| Tempering | 600-800 | Air | To reduce brittleness and improve toughness |
| Final Heat Treatment | 1050 | Air | To ensure optimal mechanical properties and corrosion resistance |
The combination of these processes ensures that Super Duplex 2507 flanges achieve the desired mechanical properties and corrosion resistance required for demanding applications in various industries.
