2205 stainless steel, also known as duplex stainless steel, is a type of stainless steel that is characterized by its two-phase microstructure consisting of both austenitic and ferritic phases. This combination of phases provides the alloy with improved strength and corrosion resistance compared to standard austenitic stainless steels. Some of the key properties of 2205 stainless steel include: High strength: 2205 stainless steel has excellent strength properties, making it suitable for use in demanding applications such as structural components and pressure vessels. Corrosion resistance: 2205 stainless steel provides good corrosion resistance in a variety of environments, including chloride-containing and acidic environments. Weldability: 2205 stainless steel is easily weldable using common welding techniques and does not require preheating or post-weld heat treatment. Fatigue resistance: 2205 stainless steel has good fatigue resistance, which makes it suitable for use in applications where cyclic loading is present. High toughness: 2205 stainless steel exhibits high toughness even at low temperatures, making it suitable for use in cryogenic applications. Overall, 2205 stainless steel is a highly versatile material that offers excellent strength and corrosion resistance properties, making it ideal for use in a wide range of demanding applications. Here are some of the most common international standards for 2205 duplex stainless steel: ASTM A240/A240M: Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications ASTM A789/A789M: Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Tubing for General Service ASTM A790/A790M: Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe EN 10088-2: Stainless steels - Part 2: Technical delivery conditions for sheet/plate and strip of corrosion resisting steels for general purposes EN 10216-5: Seamless steel tubes for pressure purposes - Technical delivery conditions - Part 5: Stainless steel tubes NACE MR0175: Sulfide stress cracking-resistant metallic materials for oilfield equipment NORSOK MDS D45: Qualification of manufacturers of duplex stainless steels UNS S31803/S32205: Unified numbering system designations for duplex stainless steels We can provide the following form:2205 stainless steel coil; 2205 stainless stee strip;2205 stainless stee plate; 2205stainless steel sheets; 2205 stainless steel tubes; 2205stainless steel pipe;2205 stainless steel flat; 2205 stainless steel bar
