Duplex forged fittings

Duplex forged fittings

Forged fittings made of duplex steel are manufactured with a high quality raw material. Duplex steel is from the family of stainless steel, and they have this name due to their metallurgical structure that consists of two phases, austenite and ferrite. Thus, the Duplex Steel Forged Fittings have properties from both material types. They are known for having relatively high strength, enhanced ductility, improved toughness, and excellent resistance to corrosion. Due to their unique properties, the Duplex Forged Fittings are widely used in chemical, oil and gas, fertilizers, engineering, and many other industries.

Refer to dimensions of 2205 duplex socket weld fittings, WNR 1.4462 threaded plug/ bushing can be available in the pressure range of Class 3000 to 6000

Whether Duplex stainless steel elbow is suitable for a high concentration of sulfuric acid depends on its specific grade. The duplex steel containing copper, like grade 1.4501, can be considered for service, including sulphuric acids. Also, alloy 310 offers good resistance against concentrated sulphuric acids at elevated temperatures. However, the other grades of the A182 F51 Socket Weld Elbow material might not be able to resist it.

The 2205 Duplex steel threaded fittings have beneficial properties from both ferritic and austenitic materials. And 2205 is the most commonly used duplex grade of stainless steel. It has a high content of chromium and molybdenum in its chemical composition, and that is why the DSS 2205 threaded fittings show excellent resistance to corrosion.

If you are buying ASTM A182 duplex steel threaded full coupling and Avesta 2205 socket weld cross from importers in Dubai, don’t forget to ask material of origin

The Duplex Steel 2205 Threaded Coupling is used for a wide range of applications, including FGD scrubber systems, seawater systems, oil field piping, chemical processing vessels, and many more.

Check specification, chemical composition, and features of WNR 1.4462 forged boss and stainless steel 2205 threaded lateral tee

The features of the WNR 1.4462 forged tee would include good resistance to pitting and crevice corrosion. It also resists stress corrosion cracking and has high tensile and yield strength.
