Alloy Steel WP22 Pipe Fittings is a type of low-alloy ferritic steel that contains chromium (Cr) and molybdenum (Mo) as its main alloying elements. It also contains small amounts of tungsten (W), nickel (Ni), and nitrogen (N) to enhance its mechanical and corrosion resistance properties. The chemical composition of WP22 typically includes the following elements: Cr (19-22%), Mo (2-3%), W (1-2%), Ni (2-3%), N (0.05-0.15%), and Fe (balance). These elements provide WP22 with excellent resistance to high-temperature corrosion, high-temperature creep, and high-temperature strength, making it ideal for use in high-pressure, high-temperature piping systems.
WP22 Alloy Steel Pipe Fittings is a versatile material used in high-temperature and high-pressure applications due to their exceptional properties. It has high-temperature strength, making it suitable for high-temperature piping systems. Thanks to its chromium content, it also has excellent resistance to high-temperature corrosion. WP22's molybdenum content provides excellent resistance to high-temperature creep. It has a good balance of toughness and strength, making it suitable for applications requiring high impact resistance. Additionally, WP22 is readily weldable, making it ideal for fabrication and piping systems. Typical applications include power plant components, piping systems in chemical plants, petrochemical refineries, and heat exchangers in the oil and gas industry.
