Thickness 0.3 - 6mm 2205 1.4462 UNS S32205 / S31803 Stainless Steel
Strip ASTM , AISI
Application
It is widely used in high-temperature and electric industry,
medical devices, construction, chemistry, food industry,
agriculture, and ship components.
It also applies to food and beverage packaging, kitchen supplies,
trains, aircraft, conveyor belts, vehicles, bolts, nuts, springs,
and screen mesh etc. .

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)
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.
