Duplex Steel S31803 Weld Neck Flanges

Wusheng Duplex Steel S31803 Weld Neck Flanges are flanges made from duplex stainless steel grade S31803, also known as 2205 stainless steel, that are designed with a weld neck or a raised face at the flange's neck. These flanges are used in piping systems where high pressure, high temperature, and/or critical applications require a robust and reliable connection.

Some key features of Duplex Steel S31803 Weld Neck Flanges include:

Duplex stainless steel: S31803 is a duplex stainless steel, which means it has a microstructure consisting of both austenite and ferrite phases. This provides it with superior mechanical properties, including higher strength and better resistance to stress corrosion cracking compared to traditional austenitic stainless steels.

Corrosion resistance: Duplex Steel S31803 Weld Neck Flanges offer excellent corrosion resistance, particularly in aggressive environments such as chloride-containing solutions. They are resistant to pitting, crevice corrosion, and general corrosion, making them suitable for use in corrosive media.

High strength: Duplex stainless steels, including S31803, have higher strength compared to austenitic stainless steels, which makes them suitable for high-pressure and high-temperature applications.

Good weldability: Duplex Steel S31803 Weld Neck Flanges can be easily welded to the pipe using butt-welding techniques, which provides a strong and leak-free connection. They do not require pre-weld or post-weld heat treatment, making them convenient to fabricate and install.
