Super Duplex Steel Flanges

Super duplex steel flanges are used in industrial piping systems and are characterised by excellent features. They are produced from austenitic and ferritic stainless steels, which makes them suitable for systems that experience very high pressures and other unfavourable conditions. They have improved mechanical characteristics and pitting or crevice corrosion resistance making them suitable for applications requiring high dependability and durability.

Features of Super Duplex Steel Flanges

Super Duplex Steel flanges are highly appreciated for their performance characteristics. Here are some key features:

• High Strength: Super Duplex Steel flanges possess higher tensile and yield strength than standard duplex and austenitic stainless steels and are, therefore, more suitable for high-pressure applications.
• Corrosion Resistance: Super duplex steel flanges are highly resistant to chloride stress corrosion cracking SCC and pitting corrosion, making them ideal for use in harsh environments.
• Ductility: Super Duplex Steel flanges have good ductility, which makes it difficult to fail under stress due to brittleness.
• Toughness: Super duplex steel flanges have high tensile strength at room and elevated temperatures making them suitable for various operations.
• Cost-Effectiveness: Super Duplex Steel flanges can be affordable in the long run since they do not require frequent replacement and maintenance.
• Temperature Resistance: Super duplex steel flanges are also capable of withstanding different temperatures and are strong at both low and high temperatures.
• Resistance to Abrasion: The hardness of super duplex steel flanges helps to offer good abrasion and erosion resistance, which is very useful in materials that are abrasive in nature.
• Weldability: Super duplex steel flanges are weldable and can be welded correctly, but the proper procedures must be followed to retain the material's properties.
• Design Flexibility: Super Duplex Steel flanges can be produced in different dimensions and types to fit certain design needs, including special orders.

All these characteristics make Super Duplex Steel flanges suitable for use in several industries.
