Distinctive Daxun Advantages
UNMATCHED CORROSION RESISTANCE Alloy 2205 offers extraordinary 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 600°F (315°C). Prolonged exposure above this temperature leads to embrittlement.
EXCEPTIONAL MECHANICAL PROPERTIES Alloy 2205 boasts more than twice the strength of traditional austenitic stainless steels in the annealed state. It can also be supplied cold-worked, with yield strength surpassing 160 ksi. It retains good toughness down to -50°F (-10°C).
VERSATILE WORKABILITY Alloy 2205 is amenable to cold forming but has a high work-hardening rate, potentially necessitating intermediate anneals. Post-forming annealing is ideal for achieving optimal stress corrosion resistance.
High-Quality Stainless Steel Seamless TubeOur stainless steel seamless tubes are manufactured from hollow sections through piercing or hot extrusion processes. These tubes are ideal for large diameter-to-wall thickness ratios, ensuring superior external dimensional tolerances.

General Properties
Duplex 2205 stainless steel pipe is a superior duplex ferritic-austenitic stainless steel composed of 22% chromium, 3% molybdenum, and 5-6% nickel. This highly sought-after grade boasts twice the yield strength of standard austenitic grades, along with exceptional fatigue strength. Its robust design ensures remarkable resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion even under severe conditions.
Applications
- Chemical Processing, Transport, and Storage - ideal for pressure vessels, tanks, piping, and heat exchangers.
- Oil and Gas Exploration and Processing Equipment - highly suitable for piping, tubing, and heat exchangers.
- Marine and Other High Chloride Environments - perfect for a range of applications.
- Effluent Scrubbing Systems - ensures optimal performance.
- Pulp and Paper Industry - excellent for digesters, bleaching equipment, and stock-handling systems.
- Cargo Tanks for Ships and Trucks - dependable for cargo transport needs.

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 offers unrivaled corrosion resistance, outperforming 316 and 316L in most environments.
- The inclusion of chromium, molybdenum, and nitrogen ensures exceptional resistance to pitting and crevice corrosion, even in oxidizing and acidic solutions.
- It withstands chloride stress corrosion cracking and operates efficiently at temperatures up to about 302°F (150°C).
- The ferrite content enhances Duplex 2205's performance in caustic environments.
Heat Resistance
- Like other duplex stainless steels, Duplex 2205 exhibits good oxidation resistance at high temperatures.
- However, it can become brittle when exposed to temperatures above 572°F (300°C) for even short durations, making it unsuitable for use above this threshold.
Welding Characteristics
- Duplex 2205 demonstrates excellent weldability.
- Welding without filler metal is generally not recommended as it may lead to excessive ferrite.
Heat Treatment
- The annealing temperature range is 1868 to 2012°F (1020 to 1100°C).
- Duplex 2205 cannot be hardened via heat treatment but will work-harden through mechanical processes.
- Special attention is required to account for its higher coefficient of thermal expansion, which can cause warping and distortion.
Processing - Hot Forming
Manufacturers recommend a maximum hot forming temperature between 2010 and 2100°F (1100 and 1150°C). Uneven cooling can lead to cracking, so maintaining consistent temperatures is crucial.
Processing - Cold Forming
The Duplex 2205 Stainless Steel Tube offers exceptional formability across numerous manufacturing processes. However, its high strength can be challenging. Even with powerful equipment, the increased springback inherent to this grade must be meticulously considered.
MACHINABILITY
Machining Duplex 2205 is somewhat more demanding than machining 300 series austenitic stainless steels, necessitating higher cutting forces and resulting in quicker tool wear. Below are essential machining guidelines: A) Employ a powerful, rigid machine with robust tool and workpiece mounts; B) Maintain short tool extensions to reduce vibration; C) Limit the tool nose radius to ensure a sharp edge on the carbide, while preserving adequate strength; D) Strategically plan the machining sequence to keep the depth of cut beneath the work-hardened layer from the prior operation.
