GENERAL PROPERTIES
Duplex 2205 Round Bar is a high-performance duplex ferritic-austenitic stainless steel comprising 22% chromium, 3% molybdenum, and 5-6% nickel. As the most widely utilized duplex stainless steel grade, it boasts a yield strength that is double that of conventional austenitic grades. This exceptional material not only delivers outstanding fatigue strength but also excels in resistance to stress corrosion cracking, crevice corrosion, pitting, erosion, and general corrosion even under the most demanding conditions.
APPLICATIONS
- Chemical processing, transport, and storage - Ideal for pressure vessels, tanks, piping, and heat exchangers
- Oil and gas exploration and processing equipment - Perfect for piping, tubing, and heat exchangers
- Marine and other high chloride environments
- Effluent scrubbing systems
- Pulp and paper industry - Suitable for digesters, bleaching equipment, and stock-handling systems
- Cargo tanks for ships and trucks
- Food processing equipment
- Biofuels plants
STANDARDS
- ASTM/ASME: A240 UNS S32205/S31803
- EURONORM: 1.4462 X2CrNiMoN 22.5.3
- AFNOR: Z3 CrNi 22.05 AZ
- DIN: W.Nr 1.4462
CORROSION RESISTANCE
- Thanks to its high content of chromium, molybdenum, and nitrogen, Duplex 2205 offers superior corrosion resistance compared to 316 and 316L in most environments.
- This composition also provides exceptional resistance to pitting and crevice corrosion, even in oxidizing and acidic solutions.
- Resistant to chloride stress corrosion cracking and capable of withstanding temperatures up to approximately 302°F (150°C).
- The presence of ferrite ensures that Duplex 2205 performs well in caustic environments.
HEAT RESISTANCE
- Duplex 2205 showcases good oxidation resistance at elevated temperatures, similar to other duplex stainless steels.
- However, it is prone to embrittlement when exposed to temperatures above 572°F (300°C) for even short durations, making it unsuitable for use above 572°F (300°C).
WELDING CHARACTERISTICS
- Duplex 2205 possesses excellent weldability.
- Generally, welding without filler metal is not recommended as it may result in excessive ferrite.
HEAT TREATMENT
- The annealing temperature range for Duplex 2205 is between 1868 to 2012°F (1020 to 1100°C).
- This material cannot be hardened by heat treatment but does work-harden.
- Special care must be taken to accommodate the higher coefficient of thermal expansion to avoid warping and distortion.
PROCESSING - HOT FORMING
Most producers recommend a maximum hot forming temperature range of 2010 to 2100°F (1100 to 1150°C). For non-compact shapes, the edges may be significantly cooler than the bulk, increasing the risk of cracking in these cooler regions.
PROCESSING - COLD FORMING
Duplex 2205 demonstrates excellent formability across various fabrications. However, its high strength can present challenges. Even with sufficient equipment power, the high strength of the grade necessitates allowances for greater spring-back.
MACHINABILITY
Duplex stainless steel bar 2205 presents a modest challenge in machining compared to 300 series austenitic stainless steel. It demands higher cutting forces, thereby accelerating tool wear. To achieve optimal results, consider these machining guidelines: A) Employ a robust, rigid machine with a very strong tool and workpiece mount; B) Minimize tool extensions to reduce vibration; C) Ensure the tool nose radius is only as long as necessary, maintaining a sharp edge on the carbide while offering adequate strength; D) Plan the machining sequence to ensure the depth of cut consistently penetrates below the work-hardened layer from the previous operation.
