Stainless Steel Drawn TubeOur stainless steel tubular products undergo advanced rolling and re-drawing processes to achieve precise final sizes. Ideal for thick-walled, large-diameter tubes, this method offers significant cost benefits over seamless tubes. All drawn tubes receive bright annealing for unmatched quality.
Daxun Advantages
CORROSION RESISTANCE Alloy 2205 features exceptional resistance to chloride-induced pitting and stress corrosion cracking.
ELEVATED TEMPERATURE RESISTANCE According to the ASME Boiler and Pressure Vessel Code, the upper-temperature limit is set at 600°F (315°C). Prolonged exposure to temperatures above this limit can cause embrittlement.
MECHANICAL PROPERTIES Alloy 2205 offers more than double the strength of conventional austenitic stainless steels in the annealed condition. It can be supplied in the cold-worked condition, achieving yield strengths exceeding 160 ksi. It maintains excellent toughness at temperatures as low as -50°F (-10°C).
WORKABILITY Alloy 2205 is conducive to cold forming, although its high work-hardening rate may necessitate intermediate anneals. Post hot or cold forming, annealing is recommended to achieve optimal stress corrosion resistance.
Stainless Steel Seamless TubeOur stainless steel seamless tubes are meticulously crafted from hollow sections produced through piercing or hot extrusion processes. These tubes are ideal for large diameter-to-wall thickness ratios and offer excellent external dimensional tolerances.

General Properties
Duplex 2205 stainless steel pipe is a high-performance duplex ferritic-austenitic stainless steel that includes 22% chromium, 3% molybdenum, and 5-6% nickel. As the most commonly utilized duplex grade, it boasts a yield strength twice that of standard austenitic grades. Additionally, it offers remarkable fatigue strength and superior resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in the harshest conditions.
Applications
- Chemical Processing, Transport and Storage - Ideal for pressure vessels, tanks, piping, and heat exchangers
- Oil and Gas Exploration and Processing Equipment - Suitable for piping, tubing, and heat exchangers
- Marine and Other High Chloride Environments
- Effluent Scrubbing Systems
- Pulp and Paper Industry - Perfect 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 heightened chromium, molybdenum, and nitrogen content, Duplex 2205 offers superior corrosion resistance compared to 316 and 316L in most environments.
- Its composition provides extraordinary pitting and crevice corrosion resistance, even in oxidative and acidic conditions.
- Resistant to chloride stress corrosion cracking and withstands temperatures up to approximately 302°F (150°C).
- The ferrite presence ensures excellent performance of Duplex 2205 in caustic environments.
Heat Resistance
- Like other duplex stainless steels, Duplex 2205 exhibits strong oxidation resistance at elevated temperatures.
- However, it is subject to embrittlement when exposed to temperatures over 572°F (300°C) for even short durations, thus it is not recommended for use above this threshold.
Welding Characteristics
- Duplex 2205 has good weldability.
- Generally, it should not be welded without filler metal to prevent excessive ferrite formation.
Heat Treatment
- The annealing temperature range is 1868 to 2012°F (1020 to 1100°C).
- Duplex 2205 cannot be hardened by heat treatment, but it does work-harden.
- Special considerations are required to accommodate its higher coefficient of thermal expansion to prevent warping and distortion.
Processing - Hot Forming
Manufacturers recommend a maximum hot forming temperature range of 2010 to 2100°F (1100 to 1150°C). If the workpiece is not uniformly heated, the cooler edges are at risk of cracking.
Processing - Cold Forming
Duplex 2205 Stainless Steel Tube showcases excellent formability across various manufacturing processes. However, its significant high strength can pose challenges. Even with robust equipment, the increased springback due to the high strength of this grade must be considered.
MACHINABILITY
Machining Duplex 2205 is slightly more challenging than machining 300 series austenitic stainless steels. It requires higher cutting forces, leading to quicker tool wear. Follow these guidelines for optimal machining: A) Use a powerful, rigid machine with strong tool and workpiece mounts; B) Keep tool extensions minimal to reduce vibration; C) Ensure the tool nose radius is not unnecessarily long, maintaining a sharp edge while providing adequate strength; D) Design the machining sequence so the depth of cut always remains below the work-hardened layer from the previous operation.
