Super Duplex 2507 Flanges
Super Duplex 2507 Flanges are high-performance components crafted from a duplex stainless steel alloy known for its exceptional strength and corrosion resistance. These flanges are widely used in demanding industrial environments where durability and reliability are critical, such as in the oil and gas, chemical processing, and marine sectors. The alloy composition typically includes a balanced mix of chromium, molybdenum, and nickel, which enhances its ability to withstand harsh conditions including chloride-induced stress corrosion cracking.
Manufactured to precise dimensions and standards, these fittings are available in various types including weld neck, slip-on, blind, and threaded flanges. Their high tensile strength and excellent resistance to pitting and crevice corrosion make them ideal for connecting pipes and equipment in high-pressure and high-temperature systems. The ferritic-austenitic microstructure of the material ensures superior mechanical properties, making it suitable for applications requiring both toughness and corrosion resistance.
Industries that rely on these components benefit from their long service life and reduced maintenance costs. They are commonly deployed in offshore platforms, desalination plants, and chemical reactors where exposure to aggressive media demands materials that perform reliably under stress. The flanges conform to international standards such as ASTM A182 and ASME B16.5, ensuring compatibility and safety across global projects.
For buyers seeking export-ready products, these flanges come with comprehensive documentation including material test reports, heat treatment certificates, and third-party inspection certifications. Packaging is designed to protect the integrity of the components during transit, making them suitable for shipment to international markets. This ensures that industrial buyers receive flanges that meet stringent quality requirements and are ready for immediate installation upon delivery.

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. The flanges are heated to a temperature range of 1020-1100°C and held for a specified time to ensure uniform temperature distribution. This process enhances the mechanical properties and prepares the material for further processing.
Forging
Forging is a crucial step in the manufacturing of Super Duplex 2507 flanges, where the steel is heated to approximately 1150-1200°C and then mechanically deformed to achieve the desired shape and structural integrity. This process improves the grain structure and enhances the overall strength of the flanges.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1050-1150 | Oil | To increase hardness and strength |
| Tempering | 300-700 | Air | To reduce brittleness and improve toughness |
| Solution Annealing | 1020-1100 | Air | To dissolve precipitates and enhance corrosion resistance |
The combination of these processes ensures that Super Duplex 2507 flanges possess optimal mechanical properties and corrosion resistance, making them suitable for various industrial applications.
