Alloy 2205 is a second-generation, nitrogen-alloyed duplex stainless steel (ferritic-austenitic). It offers an excellent combination of both strength and corrosion resistance over a wide range of applications. The approximate 50/50 ferrite-austenite structure provides excellent chloride pitting and stress corrosion cracking resistance, with roughly twice the yield strength of the standard austenitic stainless grades.

The high chromium and molybdenum content, coupled with the nitrogen addition in 2205, provides general corrosion, pitting, and crevice corrosion resistance superior to 316L and 317L.
The UNS S31803 grade stainless steel has undergone a number of modifications resulting in UNS S32205, and was endorsed in the year 1996. This grade offers higher resistance to corrosion.
2205 demonstrates superior erosion-corrosion resistance when compared to 316 stainless steel. It is not subject to intergranular corrosion in the as-welded condition. 2205 may be successfully machined by conventional methods.
The (UNS S32205) grade is a restricted-chemistry version which maintains chromium, molybdenum and nitrogen at higher levels than the (UNS S31803) composition.

Possible Alternative Grades of UNS S32750 Duplex Stainless Steel Pipe

Given below is a list of possible alternative grades, which may be chosen in place of 2205.

Table 5 - Grade specification comparisons for 2205 grade stainless steels

Grade Reasons for choosing the grade
904L Better formability is needed, with similar corrosion resistance and lower strength.
UR52N+ High resistance to corrosion is required, e.g. resistance to higher temperature seawater.
6%Mo Higher corrosion resistance is required, but with lower strength and better formability.
316L The high corrosion resistance and strength of 2205 are not needed. 316L is lower cost.
Duplex Applications of UNS S3205 Duplex Stainless Steel Pipe
Chemical processing, transport and storage
Oil and Gas exploration and processing equipment,
Marine and other high chloride environments,
Pulp and paper digesters, liquor tanks and paper machines.
Duplex corrosion Resistance of UNS S32205 Duplex Stainless Steel Pipe
Excellent general corrosion resistance; superior to Grade 316 in most environments. Excellent resistance to localized corrosion including intergranular, pitting and crevice corrosion; the CPT of 2205 is generally at least 35ºC. The grade is also resistant to chloride stress corrosion cracking (SCC) at temperatures of up to about 150ºC. Grade 2205 will often perform well in environments which cause premature failure of austenitic grades. It has better resistance to sea water then Grade 316.
Duplex Heat Resistance of UNS S32205 Duplex Stainless Steel Pipe
Although 2205 has good high temperature oxidation resistance, this grade - like other duplex stainless steels - suffers from embrittlement if held for even short times at temperatures above 300ºC. If embrittled, this can only be rectified by a full solution annealing treatment. Duplex stainless steels are almost never used above 300ºC.

Duplex Heat Treatment of UNS S32205 Duplex Stainless Steel Pipe Solution treatment (annealing) - heat to 1020ºC-1100ºC and cool rapidly. This grade cannot be hardened by thermal treatment, but does work harden.
