Duplex 2205 Stainless Plate, Alloy 2205, 2205 Q Duplex Stainless Steel Plate, Duplex UNS S31803, UNS S32205 Duplex Stainless Steel

Alloy 2205 (UNS S32305 / S31803) is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed Duplex Stainless Steel Plate with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness.

2205 Duplex Stainless Steel Plate 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.

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.

2205 is a Duplex (Austenitic-Ferritic) Stainless Steel containing about 40 - 50% ferrite in the annealed condition. 2205 has been a practical solution to chloride stress corrosion cracking problems experienced with 304/304L or 316/316L stainless. The high chromium, molybdenum and nitrogen contents provide corrosion resistance superior to 316/316L and 317L stainless in most environments. 2205 is not suggested for operating temperatures above 600°F.

The design strength of 2205 is significantly higher than 316/316L, often permitting lighter wall construction. 2205 has good notch impact toughness down to temperatures below - 40°F. 2205 is welded with E2209 or ER2209 fillers.

Corrosion Resistance

General Corrosion :
Because of its high chromium (22%), molybdenum (3%), and nitrogen (0.18%) contents, the corrosion resistance properties of 2205 Duplex Stainless Steel Plate are superior to that of 316L or 317L in most environments.

Localized Corrosion Resistance :
The chromium, molybdenum, and nitrogen in 2205 duplex stainless steel plate also provide excellent resistance to pitting and crevice corrosion even in very oxidizing and acidic solutions.

Stress Corrosion Resistance :
The duplex microstructure is known to improve the stress corrosion cracking resistance of stainless steels.

Chloride stress corrosion cracking of austenitic stainless steels can occur when the necessary conditions of temperature, tensile stress, oxygen, and chlorides are present. Since these conditions are not easily controlled, stress corrosion cracking has often been a barrier to utilizing 304L, 316L, or 317L.

Corrosion Fatigue Resistance :
Alloy 2205 duplex stainless steel plate combines high strength and high corrosion resistance to produce high corrosion fatigue strength. Applications in which processing equipment is subject to both an aggressively corrosive environment and to cycle loading can benefit from the properties of 2205 duplex stainless steel plate.


Cold Forming 2205 Grade :

Alloy 2205 duplex stainless steel plate 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 duplex stainless steel plate, forces substantially higher than those for austenitic steels are required to cold form it. Also because of the high strength, a somewhat larger allowance must be made for spring back.

Heat Treatment 2205 Grade :

Alloy 2205 duplex stainless steel plate 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.

Machinability :

With high-speed steel tooling, 2205 duplex stainless steel plate may be machined at the same feeds and speeds as Alloy 316L. When carbide tooling is used, cutting speeds should be reduced by about 20% relative to the speeds for Alloy 316L. Powerful machines and rigid mounting of tools and parts are essential.

Welding of 2205 Duplex:

Alloy 2205 duplex stainless steel plate possesses good weldability. The goal of welding 2205 is that the weld metal and heat-affected zone (HAZ) retain the corrosion resistance, strength, and toughness of the base metal. The welding of 2205 is not difficult, but it is necessary to design welding procedures that lead to a favorable phase balance after welding and will avoid precipitation of detrimental intermetallic or nonmetallic phases.

Alloy 2205 duplex stainless steel plate can be welded by: GTAW (TIG); GMAW (MIG); SMAW ("stick" electrode); SAW; FCW; and PAW.
