Stainless Steel Drawn TubeOur stainless steel tubular products undergo a meticulous rolling and re-drawing process to achieve the precise final size, ideal for thick-walled, large-diameter tubes. This advanced process offers significant cost advantages over seamless tubes. Every drawn tube is bright annealed to ensure unmatched quality.
Daxun Advantages
CORROSION RESISTANCE Alloy 2205 offers superior resistance to chloride-induced pitting and stress corrosion cracking.
ELEVATED TEMPERATURE RESISTANCE The ASME Boiler and Pressure Vessel Code sets a maximum temperature limit of 600°F (315°C). Prolonged exposure to temperatures above this threshold can lead to embrittlement.
MECHANICAL PROPERTIES Alloy 2205 boasts over twice the strength of conventional austenitic stainless steels in the annealed state. It can also be supplied in a cold-worked condition with a yield strength surpassing 160 ksi, while maintaining excellent toughness at temperatures as low as -50°F (-10°C).
WORKABILITY Alloy 2205 can be efficiently cold formed. However, due to its high work-hardening rate, intermediate anneals might be necessary. Post forming, annealing is recommended to achieve optimal stress corrosion resistance.
Stainless Steel Seamless TubeOur stainless steel seamless tubes are expertly crafted from hollow sections, made via piercing or hot extrusion processes. These tubes are ideal for large diameter-to-wall thickness ratios, providing exceptional external dimensional tolerances.

GENERAL PROPERTIES
Duplex 2205 stainless steel pipe from Jiangsu Daxun Alloy Co., Ltd. is a premium duplex ferritic-austenitic stainless steel, encompassing 22% chromium, 3% molybdenum, and 5-6% nickel. Celebrated as the most commonly utilized duplex stainless steel grade, it boasts a yield strength twice that of conventional austenitic grades. Duplex 2205 excels in fatigue strength and offers outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion even under the most severe conditions.
APPLICATIONS
- Chemical processing, transport, and storage - including pressure vessels, tanks, piping, and heat exchangers
- Oil and gas exploration and processing equipment - such as piping, tubing, and heat exchangers
- Marine and other environments with high chloride concentrations
- Effluent scrubbing systems
- Pulp and paper industry - including 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 elevated levels of chromium, molybdenum, and nitrogen, Duplex 2205 displays superior corrosion resistance compared to 316 and 316L in most environments.
- Its chemical composition also provides excellent resistance to pitting and crevice corrosion, even in oxidizing and acidic conditions.
- It is highly resistant to chloride stress corrosion cracking and can withstand temperatures up to approximately 302°F (150°C).
- The ferritic phase contributes to the impressive performance of Duplex 2205 in caustic environments.
HEAT RESISTANCE
- Like other duplex stainless steels, Duplex 2205 demonstrates robust oxidation resistance at elevated temperatures.
- However, it is prone to embrittlement if exposed to temperatures above 572°F (300°C) for even short durations, making it unsuitable for applications exceeding this temperature.
WELDING CHARACTERISTICS
- Duplex 2205 offers commendable weldability.
- For optimal results, welding should generally be carried out with filler metal to prevent excessive ferrite formation.
HEAT TREATMENT
- The annealing temperature range for Duplex 2205 is 1868 to 2012°F (1020 to 1100°C).
- While it cannot be hardened by heat treatment, Duplex 2205 does work-harden.
- Special considerations are necessary to address the higher coefficient of thermal expansion to avert warping and distortion.
PROCESSING - HOT FORMING
Most manufacturers recommend a maximum hot forming temperature between 2010 and 2100°F (1100 and 1150°C). If the workpiece is not uniformly heated, the edges may cool faster, increasing the risk of cracking.
PROCESSING - COLD FORMING
Duplex 2205 Stainless Steel Tube showcases exceptional formability across a broad spectrum of manufacturing processes. However, its high strength poses challenges. Even with adequately powerful equipment, the increased springback inherent to this grade must be meticulously accounted for.
MACHINABILITY
Duplex 2205 presents slightly greater machining challenges compared to 300 series austenitic stainless steels. Higher cutting forces are requisite, thus accelerating tool wear. Key machining guidelines include: A) Employing a robust, rigid machine with exceptionally strong tool and workpiece mounts; B) Minimizing tool extensions to reduce vibration; C) Ensuring the tool nose radius is as short as necessary to maintain a sharp edge while providing sufficient strength; D) Strategically designing the machining sequence so that the depth of cut consistently stays below the work-hardened layer from the preceding operation.
