Stainless Steel Drawn TubeOur stainless steel tubular products undergo meticulous rolling and re-drawing to attain the final size, making them perfect for thick-walled, large-diameter applications. This method offers significant cost advantages over seamless tubes, with all drawn tubes undergoing bright annealing for superior quality.
Daxun Advantages
CORROSION RESISTANCE Alloy 2205 boasts superior resistance to chloride-induced pitting and stress corrosion cracking.
ELEVATED TEMPERATURE RESISTANCE The ASME Boiler and Pressure Vessel Code sets an upper-temperature limit of 600°F (315°C). Prolonged exposure above this threshold results in embrittlement.
MECHANICAL PROPERTIES Alloy 2205 offers more than twice the strength of conventional austenitic stainless steels in the annealed condition. It can also be supplied in a cold-worked condition with yield strength surpassing 160 ksi, maintaining good toughness down to -50°F (-10°C).
WORKABILITY Alloy 2205 is amenable to cold forming, but due to its high work-hardening rate, intermediate anneals may 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 manufactured through piercing or hot extrusion processes. These tubes are ideal for applications with large diameter-to-wall thickness ratios, providing exceptional external dimensional tolerances.

General Properties
Duplex 2205 stainless steel pipe is a premium duplex ferritic austenitic stainless steel, boasting an impressive composition of 22% chromium, 3% molybdenum, and 5-6% nickel. As the most frequently utilized duplex stainless steel grade, it offers remarkable yield strength, twice that of traditional austenitic grades. With superior fatigue strength, it excels in resisting stress corrosion cracking, crevice, pitting, erosion, and general corrosion, even under the harshest conditions.
Applications
- Ideal for chemical processing, transportation, and storage, including pressure vessels, tanks, piping, and heat exchangers.
- Essential in oil and gas exploration and processing, providing reliable piping, tubing, and heat exchangers.
- Perfect for marine and other high chloride environments, offering exceptional durability.
- Optimal for effluent scrubbing systems due to its robust corrosion resistance.
- Widely used in the pulp and paper industry, particularly in digesters, bleaching equipment, and stock-handling systems.
- Highly effective for cargo tanks in ships and trucks, ensuring safe transport.
- Ideal for food processing equipment, maintaining high standards of hygiene and durability.
- Perfect for biofuels plants, ensuring efficient processing and long-lasting performance.
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 chromium, molybdenum, and nitrogen content, Duplex 2205 outperforms 316 and 316L in most environments, offering exceptional corrosion resistance.
- With robust chromium, molybdenum, and nitrogen content, it delivers high resistance to pitting and crevice corrosion in both oxidizing and acidic solutions.
- Remarkably resistant to chloride stress corrosion cracking, maintaining integrity at temperatures up to 302°F (150°C).
- The presence of ferrite enhances Duplex 2205's performance in caustic environments.
Heat Resistance
- Similar to other duplex stainless steels, Duplex 2205 offers excellent oxidation resistance at elevated temperatures.
- However, it is prone to embrittlement at temperatures above 572°F (300°C), even for short durations, and is thus not recommended for use beyond this limit.
Welding Characteristics
- Duplex 2205 boasts excellent weldability.
- Generally, it should not be welded without filler metal to avoid excessive ferrite.
Heat Treatment
- Annealing temperature range: 1868 to 2012°F (1020 to 1100°C).
- Cannot be hardened by heat treatment, but does work-harden effectively.
- Special consideration is required to account for its higher coefficient of thermal expansion, preventing warping and distortion.
Processing - Hot Forming
Manufacturers typically recommend a maximum hot forming temperature of 2010 to 2100°F (1100 to 1150°C). If not uniformly heated, cooler edges may cause cracking.
Processing - Cold Forming
The Duplex 2205 Stainless Steel Tube offers exceptional formability across various manufacturing processes. However, its significant strength can pose challenges. Even with robust equipment, the increased springback due to the high strength of Duplex 2205 must be factored into your calculations.
MACHINABILITY
Machining Duplex 2205 Stainless Steel is somewhat more challenging than working with 300 series austenitic stainless steels. It demands higher cutting forces, leading to faster tool wear. Follow these guidelines for optimal machining: A) Utilize a powerful, rigid machine with strong tool and workpiece mounts; B) Maintain short tool extensions to reduce vibration; C) Limit the tool nose radius to essential length, ensuring the carbide edge remains sharp yet strong; D) Sequence machining operations so that the depth of cut is consistently below the work-hardened layer from prior operations.
