Duplex Steel S32205 Flanges are made from ferritic-austenitic stainless steel composed of approximately 22% chromium, 5% nickel, and 3% molybdenum. This material is highly resistant to stress corrosion cracking, general corrosion, and pitting due to its high chromium content. It also has a low thermal expansion coefficient, making it suitable for high-pressure applications in chemical plants, oil refineries, power plants, and offshore production platforms. The increased strength provided by the alloy makes these flanges ideal for use in piping systems where heavier flanges are required to withstand extreme temperatures and pressures.

S32205 Duplex Steel Flanges are used in a variety of industrial applications. They have high corrosion resistance, making them ideal for chemical and marine environments. Their strength and durability make them perfect for many general-purpose applications. As far as properties go, these flanges have a high strength-to-weight ratio compared to other materials, which helps reduce the overall cost of materials. Furthermore, due to their duplex microstructure, they exhibit excellent weldability, formability and machinability. Because of these reasons, Duplex Steel flanges S32205  are highly sought after by engineers and manufacturers worldwide looking to streamline their production processes while simultaneously invoking some severe savings.

FAQ's for Duplex Steel S32205 Flanges

A Duplex Steel S32205 Flange is a type of pipe fitting used to connect two pipes together in a piping system. It has an outwardly projecting flange at one end that provides a loose fit when connected to another pipe or fitting. The other end has threads or welded seams that allow it to be securely attached and sealed.

Inconel 783 Plates Starts At Rs 1600/Piece To Rs 2000/Piece

The main advantage of using a Duplex Steel S32205 Flange is its strength and corrosion resistance. Its high chromium and molybdenum content makes it highly resistant to corrosion and pressure, while its high mechanical strength gives it excellent wear and fatigue resistance in demanding applications.
