All 2205 alloys are metallographically inspected to ensure that products shipped are free of harmful phases such as sigma. It is usually used in the form of welded pipes or tubular parts. The alloy is also used as formed and welded sheet products in environments that are resistant to general corrosion and chloride stress corrosion cracking.

Super Duplex Flanges use pure quality alloys with mixed austenitic and ferritic microstructures and high molybdenum and chromium content. This superior chemical composition provides superior resistance and increased strength. The products we manufacture are used in a wide variety of applications and industries. These flanges are highly resistant in corrosive, acidic and reducing environments.

Duplex steel flanges have some excellent properties such as strong construction, higher yield strength, superior finish, higher toughness, corrosion resistance, and more. It is widely used in various applications and industries. These flanges are highly resistant in corrosive, acidic and reducing environments.

Duplex flanges are dual microstructures consisting of austenitic and ferritic grades. Versatile grades are designed with excellent chemical concentrations of chromium, nickel and small amounts of molybdenum. The excellent concentration makes these modules more resistant to aggressive and oxidizing media.

Robust modules resist acid pitting in marine systems. Duplex flanges effectively connect different piping modules in the system and affect the flow of fluids or gases. This grade has higher strength and crack resistance than common austenitic grades. These flanges also have excellent ductility and can be welded in place using standard procedures.

Stainless steel grades with more than 12% chromium in the alloy are resistant to the effects of oxidation. In the case of super duplex stainless steel 2507, its alloy contains 25% chromium, which improves oxidation resistance even at high temperatures.

Both austenite and ferrite are present in the microstructure of this alloy. Therefore, super duplex flanges have similar properties to these two stainless steels. These components have excellent performance in applications exposed to chlorine solutions.

The austenitic portion of this alloy is the reason why A182 Super Duplex Flanges resist pitting, crevice, and general corrosion. Typically organic acids such as acetic and formic acids cause uniform corrosion in many steel alloys. Molybdenum, which contains a high chromium content, makes UNS S32750 butt weld flanges resistant to corrosion in environments containing these acids.

Due to the alloy’s excellent resistance to dilute hydrochloric acid, Super Duplex 2507 flanges can be used in the chemical processing industry. Another common problem with steel alloys is that they tend to corrode during welding. When the alloy is welded, the temperature is high, and the excess carbon atoms are precipitated to form carbide precipitates.

In addition to this standard duplex grade, there are super duplex and lean duplex grades. Flanges made of duplex steel fall under ASTM A182 F51 UNS S31803 and others. ASTM A182 specification covers components for pressure vessel grade applications. These duplex flanges can be used in high pressure and high temperature services such as boilers, condensers, heat exchangers, power plants, and petroleum industry applications.

Each different type has its own advantages. Different grades of duplex steel have different mechanical and physical properties due to different chemical compositions. ASTM A182 F60 flanges are high performance, cost effective and long life flanges. There are different face types such as ring joint flanges, flat face flanges and raised face flanges.

The combination of chromium, molybdenum and nitrogen provides Duplex 2205 flanges with good chloride pitting and crevice corrosion protection, which makes them useful in marine environments, brackish water, bleach operations, closed loop water systems and some food processing applications. Although it is important to remember that pitting corrosion can be a problem in chloride solutions when oxidizing media are present. Under these conditions, the passive (protective) layer of the Duplex 2205 material may be damaged and localized pitting may occur.

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.

Butt weld flanges are the most popular type of high pressure pipeline flange.
