What are Duplex Steel S31803 Flanges?

Duplex Steel S31803 Flanges are flange fittings made from duplex stainless steel grade S31803. Duplex stainless steel offers excellent corrosion resistance and high strength, making it suitable for various industrial applications. S31803 flanges are commonly used in industries such as oil and gas, chemical processing, and offshore installations, where resistance to corrosion & mechanical strength are critical.

What is Duplex Steel S32205 Flange used for?

Duplex Steel S32205 Flange is specifically used for applications with higher corrosion resistance than S31803. S32205 is a duplex stainless steel grade with improved pitting and crevice corrosion resistance. These flanges are commonly used in environments containing chloride ions, such as seawater applications, desalination plants, and chemical processing plants.

What are the advantages of Duplex Steel 2205 Flanges?

The advantages of Duplex Steel 2205 Flanges include superior corrosion resistance, especially in harsh environments with high chloride content. They offer high strength and excellent toughness, allowing them to withstand extreme temperatures and pressures. Duplex Steel 2205 Flanges also provide good weldability & formability, making them easy to work with during installation. Their combination of properties makes them ideal for demanding applications, ensuring reliable & long lasting performance.
