ASTM A240 2205 DSS-UNS S 31803-NACE MR 0175 Solution Annealed Condition Duplex Plate 6000 x 1500 x 6 thk
UNS S31803/2205 is a duplex grade with a ferritic-austenitic microstructure. The alloy consists of around 40-50% ferrite in the annealed condition. The duplex microstructure has the high strength of the ferritic grades whilst retaining the corrosion resistance of the austenitic grades. It is not uncommon to see the metal used as a practical solution to chloride-induced stress cracking, which is the achilles’ heel of stainless steel.
It has superior resistance to chloride pitting and crevice corrosion as compared to 317L stainless steel. The alloy has outstanding corrosion resistance to seawater and most concentrations of sulphuric acid. In addition, it is also resistant to sulphide stress corrosion cracking (sour-gas environments).
The high quality and therefore performance of UNS S32205 is widely attributed to the high levels of chromium present as well as nitrogen and molybdenum.

DUPLEX APPLICATIONS
- 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
S32205 offers excellent general corrosion resistance and is superior to Grade 316 in most environments, providing excellent resistance to localized corrosion including intergranular, pitting and crevice corrosion. The CPT of S32205 is generally at least 35ºC with resistance to chloride stress corrosion cracking (SCC) at temperatures of up to about 150ºC. With better sea water resistance than Grade 316, S32205 often performs well in environments where premature failure of austenitic grades is observed.
DUPLEX HEAT RESISTANCE
Duplex stainless steels are almost never used in environments above 300ºC. While the grade has good resistance to high temperature oxidation S32205, like other duplex stainless steels, suffers from embrittlement even for short periods in temperatures above 300ºC. This can only be rectified by a full solution annealing treatment.
DUPLEX HEAT TREATMENT
Solution treatment (annealing) entails heating to 1020ºC-1100ºC and then rapid cooling. This grade cannot be hardened by thermal treatment, but does work harden.
