ASTM A789 UNS S32205 Duplex Stainless Steel Tubes
UNS S32205 is a duplex stainless steel with a microstructure,when heat treated properly,od nearly equare proportions of austenite and ferrite.This microsturcture ensures that S32205 is much more resistant to stress corrosion cracking than SS304 and SS316L.The higher chromium,molybdenum and nitrogen contens give SS2205 significantly improved pitting and crevice-corrosion resistance in the presence of chlorides.SS2205 also has better general corrosion resistance than SS316L in most environment.In addition,SS2205 has a 0.2% Proof Stress of about double that of conventional austenitic stainless steels.

UNS S32205 Duplex Stainless Steel Tubes Corrosion Resistance
Grade 2205 stainless steel exhibits excellent corrosion resistance, much higher than that of grade 316. It resists localized corrosion types like intergranular, crevice and pitting. The CPT of this type of stainless steel is around 35°C. This grade is resistant to chloride stress corrosion cracking (SCC) at temperatures of 150°C. Grade 2205 stainless steels are apt replacements to austenitic grades, especially in premature failure environments and marine environments.
UNS S32205 Duplex Stainless Steel Tubes Heat Resistance
The high oxidation resistance property of Grade 2205 is marred by its embrittlement above 300°C. This embrittlement can be modified by a full solution annealing treatment. This grade performs well at temperatures below 300°C.
Welding Characteristics:
1, Possesses good weldability
2, Should not generally be welded without filler metal as this may result in excessive ferrite
Κατεργασία με θερμοκρασία:
1, Annealing temperature range is 1868 to 2012°F (1020 to 1100°C)
2, Cannot be hardened by heat treatment – but Duplex 2205 does work-harden
3, Special consideration is needed to compensate for a higher coefficient of thermal expansion to avoid warping and distortion
Διπλός 2205 μηχανική ικανότητα:
Διπλός 2205 is somewhat more difficult to machine than the 300 series austenitic stainless steels. Higher cutting forces are required and more rapid tool wear is typical. Some guidelines for machining are: ΕΝΑ) Use powerful, rigid machines with extremely strong rigid mounting of tools and work piece, σι) Minimize vibration by keeping the tool extension as short as possible, ντο) Use a nose radius on the tool, no longer than necessary, for carbides that have a sharp edge while still providing adequate strength, ρε) Design machining sequences to always provide for a depth of cut below the work hardened layer resulting from the previous passes.
Applications
1)Chemical process vessels, piping and heat exchangers
2)Pulp mill digesters, bleach washers, chip pre-steaming vessels
3)Food processing equipment
4)Oil field piping and heat exchangers
5)Flue gas desulfurization equipment
