Stainless Steel Duplex Steel Plate ASME SA240 S32205 , S31803
we has an extensive inventory of 2205 stainless steel plate in
thicknesses from 3/16" through 3". The yield strength is about
twice that of austenitic stainless steels, thus allowing a designer
to save weight and making the alloy more cost competitive when
compared to 316L or 317L.
Alloy 2205 (UNS S32305/S31803) is a 22% chromium, 3% molybdenum,
5-6% nickel, nitrogen alloyed duplex stainless steel with high
general, localized, and stress corrosion resistance properties in
addition to high strength and excellent impact toughness.
Alloy 2205 provides pitting and crevice corrosion resistance
superior to 316L or 317L austenitic stainless steels in almost all
corrosive media. It also has high corrosion and erosion fatigue
properties as well as lower thermal expansion and higher thermal
conductivity than austenitic.
General Properties
Alloy 2205 is a 22% Chromium, 3% Molybdenum, 5-6% Nickel nitrogen alloyed duplex stainless steel with high general, localized and stress corrosion resistance properties in addition to high strength and excellent impact toughness.

The yield strength is about twice that of austenitic stainless
steels. This allows a designer to save weight and makes the alloy
more cost competitive when compared to 316L or 317L.
Alloy 2205 is particularly suitable for applications covering the
-50°F/+600°F temperature range. Temperatures outside this range may
be considered but need some restrictions, particularly for welded
structures.
Applications
- Pressure vessels, tanks, piping, and heat exchangers in the chemical processing industry
- Piping, tubing, and heat exchangers for the handling of gas and oil
- Effluent scrubbing systems
- Pulp and paper industry digesters, bleaching equipment, and stock-handling systems
- Rotors, fans, shafts, and press rolls requiring combined strength and corrosion resistance
- Cargo tanks for ships and trucks
- Food processing equipment
- Biofuels plants

Processing
Hot Forming
Forming below 600°F is recommended whenever possible. When hot forming is required, the workpiece should be heated uniformly and worked in the range of 1750 to 2250°F. Alloy 2205 is quite soft at these temperatures and is readily formed. Above this range, 2205 is subject to hot tearing. Immediately below this range, the austenite becomes substantially stronger than the ferrite and may cause cracking, a particular danger to “cold” edges. Below 1700°F there can be rapid formation of intermetallic phases because of the combination of temperature and deformation. Whenever hot forming is done, it should be followed by a full solution anneal at 1900°F minimum and rapid quench to restore phase balance, toughness, and corrosion resistance. Stress relieving is not required or recommended; however, if it must be performed, the material should receive a full solution anneal at 1900°F minimum, followed by rapid cooling or water quenching.

Cold Forming
Alloy 2205 is readily sheared and cold formed on equipment suited to working stainless steels. However, because of the high strength and rapid work hardening of 2205, forces substantially higher than those for austenitic steels are required to cold form 2205. Also because of the high strength, a somewhat larger allowance must be made for springback.

Heat Treatment
Alloy 2205 should be annealed at 1900°F minimum, followed by rapid cooling, ideally by water quenching. This treatment applies to both solution annealing and stress relieving. Stress relief treatments at any lower temperature carry the risk of precipitation of detrimental intermetallic or nonmetallic phases.
