WUXI XINFUTIAN METAL PRODUCTS CO., LTD now includes Duplex 2205 (UNS S32205 / S31803), in sheet, sheet coil, plate, plate coil, round bar, pipe processed flat bar and tubular products. Duplex 2205 is ideally suited for high-pressure and highly corrosive environments.
 
1.Products Details
 
Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel. It is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades. It also demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.

2. Corrosion
 
Corrosion Resitance
1. Due to its high chromium, molybdenum, and nitrogen content, Duplex 2205 demonstrates superior corrosion resistant properties to 316 and 316L in most environments
2. Chromium, molybdenum, and nitrogen content also provide high resistance to pitting and crevice corrosion, even in oxidizing and acidic solutions
3.Resistant to chloride stress corrosion cracking and temperatures of up to about 302°F (150°C)
4. The presence of ferrite provides for good performance of Duplex 2205 in caustic environments
 
Heat Resitance
1.Similar to other duplex stainless steels, Duplex 2205 has good oxidation resistance at high temperatures
2. 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)
 
3. Process
 
Welding Characteristics
A. Possesses good weldability
B. Should not generally be welded without filler metal as this may result in excessive ferrite
Heat-Treatment
A. Annealing temperature range is 1868 to 2012°F (1020 to 1100°C)
B. Cannot be hardened by heat treatment – but Duplex 2205 does work-harden
C.Special consideration is needed to compensate for a higher coefficient of thermal expansion to avoid warping and distortion
Process -hot forming
Most Duplex 2205 producers recommend a maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). If the shape of the work piece is not compact, the edges may be significantly cooler than the bulk, and there is risk of cracking in the cooler regions.
Process -Cold Forming
Duplex 2205 has shown good formability in a variety of fabrications. The high strength of Duplex 2205 can pose problems. Even when the equipment has sufficient power, allowance must be made for higher spring-back caused by the grade’s high strength.
