Daxun's Unmatched Benefits
Unrivaled CORROSION RESISTANCE Alloy 2205 shines with superb resistance to chloride-induced pitting and stress corrosion cracking.
Superior 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 above this threshold can lead to embrittlement.
Outstanding MECHANICAL PROPERTIES Alloy 2205 offers more than double the strength of conventional austenitic stainless steels in the annealed condition. Available in cold-worked condition, it boasts a yield strength exceeding 160 ksi and retains excellent toughness at temperatures down to -50°F (-10°C).
Versatile WORKABILITY Alloy 2205 is amenable to cold forming, though its high work-hardening rate requires intermediate anneals. Post-annealing is advised following hot or cold forming to attain optimal stress corrosion resistance.

GENERAL PROPERTIES
The Duplex 2205 stainless steel pipe, an exceptional grade among duplex ferritic-austenitic stainless steels, consists of 22% chromium, 3% molybdenum, and 5-6% nickel. Distinguished as the most widely utilized duplex stainless steel, it boasts a yield strength that is double that of standard austenitic grades. Furthermore, it excels in fatigue strength and stands out in its remarkable resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion, making it ideal for severe 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 - Offers superior corrosion resistance.
- Effluent Scrubbing Systems - Reliable performance in harsh conditions.
- Pulp and Paper Industry - Optimal for digesters, bleaching equipment, and stock-handling systems.
- Cargo Tanks for Ships and Trucks - Ensures durability and safety.
- Food Processing Equipment - Maintains hygiene and resistance to corrosion.
- Biofuels Plants - Adaptable and robust in biofuel processing.
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 showcases superior corrosion resistance compared to 316 and 316L in most environments.
- The supplementary chromium, molybdenum, and nitrogen content also ensures high resistance to pitting and crevice corrosion, even in oxidizing and acidic solutions.
- Remarkably resistant to chloride stress corrosion cracking and can withstand temperatures up to approximately 302°F (150°C).
- The ferrite presence enhances Duplex 2205's performance in caustic environments.
HEAT RESISTANCE
- Similar to other duplex stainless steels, Duplex 2205 exhibits excellent oxidation resistance at elevated temperatures.
- Nonetheless, it is prone to embrittlement when exposed to temperatures above 572°F (300°C) for even short durations; thus, its use is not advised above this temperature.
WELDING CHARACTERISTICS
- Duplex 2205 possesses commendable weldability.
- However, welding without filler metal is generally discouraged due to the potential for excessive ferrite formation.
HEAT TREATMENT
- The annealing temperature range is between 1868 to 2012°F (1020 to 1100°C).
- Duplex 2205 cannot be hardened by heat treatment, though it work-hardens effectively.
- Special attention is required to account for its higher coefficient of thermal expansion to prevent warping and distortion.
PROCESSING - HOT FORMING
Most manufacturers recommend a maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). If the workpiece lacks uniformity, the edges may cool more rapidly than the bulk, raising the risk of cracking in cooler areas.
PROCESSING - COLD FORMING
Duplex 2205 Stainless Steel Tube showcases exceptional formability across diverse manufacturing processes. Despite its high strength posing potential challenges, it's crucial to consider the increased springback associated with this grade, even when utilizing powerful equipment.
MACHINABILITY
Duplex 2205 presents a higher machining difficulty compared to 300 series austenitic stainless steels. Elevated cutting forces are necessary, which accelerates tool wear. For optimal results, adhere to these guidelines: A) Utilize a robust, rigid machine with secure tool and workpiece mounts; B) Minimize tool extensions to reduce vibration; C) Maintain a short tool nose radius to ensure the carbide retains sharpness while maintaining strength; D) Plan the machining sequence to ensure the depth of cut stays below the work-hardened layer from previous operations.
