Super Duplex Steel UNS S32760 Pipe Fittings – Manufacturer, Supplier & Exporter in Mumbai, India

What are Super Duplex Steel UNS S32760 Pipe Fittings?

Super Duplex Steel UNS S32760 Pipe Fittings are industrial piping components used to connect pipes, change the direction of flow, and control fluid movement in piping systems. These fittings are manufactured from Super Duplex Stainless Steel UNS S32760, which has a balanced microstructure consisting of austenite and ferrite phases.

This duplex structure provides a combination of very high strength and outstanding corrosion resistance, making it suitable for highly aggressive environments.

Super duplex stainless steel contains alloying elements such as chromium, nickel, molybdenum, nitrogen, and tungsten, which significantly enhance resistance to corrosion and mechanical performance.

Super Duplex UNS S32760 pipe fittings are commonly used for:

• Connecting pipelines
• Changing flow direction
• Branching pipeline systems
• Controlling fluid movement

These fittings are widely used in oil & gas, marine, offshore platforms, desalination plants, chemical processing, and power generation industries.
