Stainless Steel Welded TubesOur stainless steel tubular products, crafted from stainless steel strips, are roll-formed and fusion-welded along the longitudinal seam. Daxun's welding process is exemplary, utilizing no filler metal whatsoever.
Quick Response
- High resistance to stress corrosion cracking, fatigue and erosion
- Higher thermal conductivity and lower thermal expansion than austenitic steels
- Excellent and uniform resistance to pitting and crevice corrosion
- Good resistance to sulfide stress corrosion cracking
- Usable up to 600°F
- High yield strength
- Good fatigue strength
- Excellent corrosion resistance
Stainless Steel Drawn TubeOur stainless steel tubular products undergo rolling and re-drawing to achieve the final size, ideal for thick-walled, large-diameter tubes. This process offers cost benefits over seamless tubes, and all drawn tubes are bright annealed for superior quality.
Daxun Advantages
CORROSION RESISTANCEAlloy 2205 has excellent resistance to chloride-induced pitting and stress corrosion cracking.
ELEVATED TEMPERATURE RESISTANCEThe ASME Boiler and Pressure Vessel Code places an upper-temperature limit of 600°F (315°C). Exposure to temperatures above this for extended periods results in embrittlement.
MECHANICAL PROPERTIESAlloy 2205 has more than twice the strength of conventional austenitic stainless steels in the annealed condition. It can also be provided in the cold-worked condition with yield strength exceeding 160 ksi. It maintains good toughness at temperatures down to -50°F (-10°C).
WORKABILITYAlloy 2205 can be cold formed. However, it has a high work-hardening rate, so intermediate anneals may be required. Annealing is also recommended subsequent to hot forming or cold forming in order to achieve optimal stress corrosion resistance.
Stainless Steel Seamless TubeOur stainless steel seamless tubes are crafted from hollow sections made via piercing or hot extrusion processes. These tubes are perfect for large diameter-to-wall thickness ratios, offering excellent external dimensional tolerances.

GENERAL PROPERTIES
Duplex 2205 stainless steel pipe is a duplex ferritic austenitic stainless steel containing 22% chromium, 3% molybdenum and 5-6% nickel. It is the most commonly used duplex stainless steel grade and has a yield strength twice that of regular austenitic grades. It also has excellent fatigue strength and has excellent resistance to stress corrosion cracking, crevice, pitting, erosion and general corrosion in severe conditions.
APPLICATIONS
- Chemical processing, transport and storage - pressure vessels, tanks, piping, and heat exchangers
- Oil and gas exploration and processing equipment - piping, tubing, and heat exchangers
- Marine and other high chloride environments
- Effluent scrubbing systems
- Pulp and paper industry - 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
- Due to its high chromium, molybdenum, and nitrogen content, Duplex 2205 demonstrates superior corrosion resistant properties to 316 and 316L in most environments
- Chromium, molybdenum, and nitrogen content also provide high resistance to pitting and crevice corrosion, even in oxidizing and acidic solutions
- Resistant to chloride stress corrosion cracking and temperatures of up to about 302°F (150°C)
- The presence of ferrite provides for good performance of Duplex 2205 in caustic environments
HEAT RESISTANCE
- Similar to other duplex stainless steels, Duplex 2205 has good oxidation resistance at high temperatures
- Subject to embrittlement when exposed to temperatures above 572°F (300°C) even when exposed for short periods of time; Duplex 2205 is therefore not recommended for use above 572°F (300°C)
WELDING CHARACTERISTICS
- Possesses good weldability
- Should not generally be welded without filler metal as this may result in excessive ferrite
HEAT TREATMENT
- Annealing temperature range is 1868 to 2012°F (1020 to 1100°C)
- Cannot be hardened by heat treatment - but Duplex 2205 does work-harden
- Special consideration is needed to compensate for a higher coefficient of thermal expansion to avoid warping and distortion
PROCESSING - HOT FORMING
Most duplex 2205 steel pipe manufacturers recommend a maximum hot forming temperature between 2010 and 2100°F (1100 and 1150°C). If the workpiece is not compact, the edge may be much cooler than the bulk, and there is a risk of cracking in the cooler area.
PROCESSING - COLD FORMING
Duplex 2205 Stainless Steel Tube exhibits good formability in a variety of manufacturing processes. The high strength of Duplex 2205 can be problematic. Even if the equipment is powerful enough, the higher springback caused by the high strength of this grade must be taken into account.
MACHINABILITY
Duplex 2205 is slightly more difficult to machine than 300 series austenitic stainless steels. Higher cutting forces are required, so the tool wears more quickly. Here are some machining guidelines: A) Use a powerful, rigid machine with very strong tool and workpiece mounts; B) Keep tool extensions short to minimize vibration; C) Do not make the tool nose radius longer than necessary so that the carbide has a sharp edge while still providing adequate strength; D) Design the machining sequence so that the depth of cut is always below the work-hardened layer from the previous operation.
