2205 duplex stainless steel strip composed of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. 2205 duplex stainless steel strip 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.

2205 Stainless Steel Strip Chemical Composition

Grade	Standard	C	Si	Mn	P	S	Cr	Ni	Mo

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

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 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.

Processing – 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.
