2205 combines many of the beneficial properties of ferritic and austenitic steels and is the most widely used duplex stainless steel grade. Its high chromium and molybdenum content gives stainless steel excellent corrosion resistance.
In the case of 2205, it is a popular duplex grade containing approximately 22% chromium, 5% nickel, 3% molybdenum, and the balance iron. The name "2205" is derived from its composition, as it typically contains about 22% chromium and 5% nickel.
Grade 2205 stainless steel is a duplex stainless steel consisting of a combination of austenitic and ferritic grades. It contains high levels of chromium and molybdenum, which make it highly resistant to corrosion and pitting. 2205 stainless steel pipe is commonly used in industrial applications that require high strength and corrosion resistance, such as chemical processing plants, oil refineries, and offshore oil rigs.
2205 stainless steel has excellent corrosion resistance, high strength and good weldability. It exhibits higher resistance to stress corrosion cracking than austenitic stainless steels. The presence of molybdenum enhances its resistance to pitting and crevice corrosion, making it suitable for a variety of applications in industries such as chemical processing, oil and gas, and marine environments.
