Use of duplex and super duplex stainless steels should be limited to below 570¡ãF, as prolonged exposure to high temperatures can make the material brittle.

Duplex 2205, UNS S32205, is a stainless steel material that derives its “duplex” name from a mixed microstructure containing roughly equal portions of ferrite and austenite. This grade is the most popular variety, and this two-phase material is a significant upgrade over 316 stainless steel in terms of yield strength and corrosion resistance.

Super Duplex 2507, UNS S32750, is a duplex stainless steel especially suitable for environments such as warm chlorinated seawater and acidic chlorinated media. It has similar properties to Duplex 2205 but is more corrosion resistant and performs well in moderately corrosive environments.

Double butt weld flanges are best suited for hazardous high pressure applications. Butt weld flanges are easily identified by their long tapered neck.

The flanges are internally drilled to match the inside diameter of the pipe to ensure unrestricted flow and prevent turbulence at the joint. The tapered neck provides thicker metal at the flange joint, while the neck tapers to butt against the pipe and to butt against the pipe. This design helps transfer stress from the flange to the pipe and reduces stress concentrations at the bottom of the flange connection.

Duplex and Super Duplex Welding Flanges are ideal for critical applications involving high pressure, sub-zero and high temperature, as well as conditions where fluctuations cause expansion/contraction of the pipeline, and its main feature is that it is suitable for high pressure applications.

For many applications where 300 series stainless steel is susceptible to chloride stress corrosion cracking, 2205 duplex stainless steel is a cost-effective solution. Stress corrosion cracking occurs when stainless steel is subjected to tensile stress while in contact with solutions containing chlorides. Elevated temperatures also increase the susceptibility of stainless steel to stress corrosion cracking.

The combination of chromium, molybdenum and nitrogen gives 2205 good resistance to chloride pitting and crevice corrosion. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications. The high chromium, molybdenum and nitrogen content of 2205 provides better corrosion resistance than common stainless steels such as 316L and 317L in most environments, and Citizen Metals has been actively involved in ensuring the best possible quality for our customers.
