Duplex Steel UNS S32205 Pipe Fittings

Duplex Steel S32205 Welded Pipe Fittings have longer service lives even when exposed to harsh environmental conditions, such as salty water or high pressures/temperatures, due to their superior strength levels compared to other materials such as carbon steel or aluminum alloys. Adding molybdenum provides superior protection against corrosive elements such as saltwater or acidic media, which can cause damage to other materials over time.

As a leading supplier and manufacturer in China, GNEE Steel provides cost-effective nickel-based alloy products.

Product Introduction

Duplex Steel S32205 Pipes Fittings are composed primarily of iron, chromium, and nickel, with molybdenum added to enhance their corrosion-resistant properties. It is also known for its high strength-to-weight ratio and excellent weldability. The addition of molybdenum reduces the risk of pitting in chloride environments by forming protective oxide films on the surface. As such, it is often used in marine or offshore environments where corrosion resistance is needed. In addition to its excellent corrosion resistance, Duplex Steels UNS S32205 Pipe Fittings offer superior mechanical properties compared to conventional stainless steels due to their higher strength levels.

duplex tube fittings

Due to its superior corrosion resistance, Duplex UNS S32205 Butt Weld Fitting can be used in various industries and applications where other materials may not be suitable. These include petrochemical plants, seawater systems, oil & gas production platforms, desalination plants, chemical processing units, pharmaceutical plants, etc. It is also extensively used in pipelines carrying sour gas or crude oil since it offers superior resistance against sour gas attack (H2S). Additionally, these fittings can be used for pressure vessel components such as pumps and valves that require high levels of strength and durability. We also manufacture Duplex Steels UNS S31803 Pipe Fitting.

Difference Between UNS S32205 Pipe Fitting and UNS S31803

UNS S32205 and UNS S31803 are both duplex stainless steels grades, but they have some differences. UNS S32205 has a higher nitrogen content and slightly higher chromium and molybdenum levels, which increases corrosion resistance and strength compared to UNS S31803. UNS S32205 has a higher minimum yield strength and is generally considered more resistant to stress corrosion cracking.
