CORROSION RESISTANCE
Chloride Stress Corrosion Cracking
Resistance
The nickel-free ferritic steels are essentially immune to chloride stress corrosion cracking even in the extremely severe boiling 42% magnesium chloride test. Nickel-containing austenitic stainless steels, on the other hand, are highly susceptible to stress corrosion cracking. The resistance of austenitic and ferritic stainless steels to chloride stress corrosion cracking has been correlated to the nickel content of the alloys.
Duplex alloys behave in a manner that is a combination of the characteristics of the austenitic and ferritic phases that make up the alloy, as shown by the data below. Certain elements tend to partition into one of the two primary phases in duplex alloys. For example, the nickel content of the ferrite phase will be lower than that of the austenite phase relative to the bulk composition. Consequently, the ferrite phase in AL 2205 alloy will provide resistance to chloride stress corrosion cracking, making it substantially better than the standard 300 series austenitic stainless steels.

Effect of Elevated Temperature on Mechanical Properties
An upper temperature limit of 600°F (316°C) has been placed on the use of AL 2205 alloy in the ASME Boiler and Pressure Vessel Code due to what is known as Ò885°F (475°C) Embrittlement.Ó This means that the ferrite phase of AL 2205 alloy may be embrittled after exposure to temperatures from 650 to 1000°F (343-538°C). The 885°F (475°C) embrittlement is reversible by heat treating the alloy at a temperature above 1100°F (593°C). However, another embrittling range exists from about 1000°F (538°C) to 1830°F (1000°C) due to the precipitation of excess phases that are detrimental to both impact and corrosion properties. A full anneal and rapid cooling treatment is required to eliminate the latter form of embrittlement and is also the preferred manner of relieving forming stresses and 885°F (475°C) embrittlement.
Heat Treatment
The AL 2205 alloy should be annealed between 1870 and 2010°F (1020-1100°C) and cooled quickly. Annealing near 2010°F will increase the amount of ferrite present in the microstructure compared to that resulting from annealing near 1870°F. The graph below provides additional information.
