Duplex Alloy 2205 UNS UNS UNS S32205 / S31803 2205 Duplex stainless
steel strips overview
Duplex Alloy 2205 is the most widely used duplex stainless steel
grade and is characterized by high yield strength, double that of
the standard austenitic stainless steel grades.
2205 stainless steel strip is a duplex stainless steel strip
composed of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen
alloy.
It has high strength, good impact toughness and good overall and
local stress corrosion resistance.
The yield strength of duplex 2205 stainless steel strip is more
than twice that of normal austenitic stainless steel strip.
This feature enables engineers and designers to reduce weight when
designing related products, making this strip more cost-effective
than 316L stainless steel strip and 317L stainless steel strip.
This strip is especially suitable for the temperature range of from
-50°F to +600°F.

Duplex Alloy 2205 UNS UNS UNS S32205 / S31803 2205 Duplex stainless

cracking, S31803/S32205 is finding wide use in place of austenitic
stainless steels for handling solutions containing chlorides such
as in marine scrubbers. As a result of its wear, erosion and
corrosion resistance, S31803/S32205 is particularly suitable for
pumps, agitators and other critical components handling hot

|
| Characteristics | - High Strength AND
- Duplex UNS S31803/S32205 is a ferritic-austenitic stainless
combining high mechanical strength, ductility and hardness with
excellent resistance to corrosion and erosion.
|
| Mechanical Properties | - Mechanical Test Requirements:
- Tensile - 90,000 psi min
- Yield - 65,000 psi min
- Elongation - 25 % min
- Hardness - 293 HBN Max
- Corrosion Resistance:
- The corrosion resistance of S31803/S32205, under most conditions of
service, is superior to that of the fully austenitic type 304, 316
and 317L stainless steels. It has excellent resistance to sulfuric,
phosphoric, nitric, and many other acids and salts.
- Duplex UNS S31803/S32205 is highly resistant to acetic, formic and
other organic acids and compounds. It is particularly suitable for
the higher concentrations and temperatures where pitting and
preferential corrosion are common causes of failure with most
conventional austenitic stainless steels in the presence of
chlorides and other impurities. Like the austenitic stainless
steels, S31803 is not generally suitable for handling hydrochloric
acid and other severely reducing acids and chemicals.
- Stress-Corrosion Resistance:
- Resists Chloride Stress Corrosion Cracking
- Duplex UNS S31803/S32205 has improved resistance to
stress-corrosion cracking, crevice corrosion and pitting when
compared to austenitic stainless steels such as types 304, 316,
317L and even the 20Cr-25Ni grades. It is highly resistant to
stress-corrosion cracking in sodium chloride, seawater and many
other environments.
|
| Fabrication | - Hot forming is carried out at 1150-950˚C. However, it should be
borne in mind that the mechanical strength of the material is low
at high temperatures. At temperatures below 950˚C embrittling can
take place on account of the combination of strain and exposure in
the sigma phase field. Quench annealing is normally required after
hot forming.316, 317L and even the 20Cr-25Ni grades. It is highly
resistant to stress-corrosion cracking in sodium chloride, seawater
and many other environments.
- Cold forming owing to the high yield strength of the steel, greater
forces are normally required for the cold forming of S31803/ S32205
than for austenitic steels.
|
| Machining | - High alloy duplex steels, such as S31803/S32205, are generally more
difficult to machine than conventional austenitic stainless steels
such as 17-12-2.5. Duplex steels have a somewhat different property
profile than highly alloyed austenitic stainless steels. The main
difference is that duplex grades are relatively easier to machine
with high speed steel tools than with cemented carbide tools,
compared to austenitic stainless steels with a similar alloy
content.
|
| Welding | - Duplex UNS S31803/ S32205 possesses good weldability. The following
instructions should be followed:
- The material should be welded without preheating.
- The material should be allowed to cool between passes, preferably
to below 150℃.
- The recommended heat input in order to achieve a good balance
between ferrite and austenite in the weld is 1.0-2.5 kJ/mm (aim at
30-60% ferrite). The energy input should be adjusted in proportion
to the thickness of the material to be welded. A high energy input
and slow cooling reduce the amount of ferrite.
- Duplex UNS S31803/ S32205 can be welded using the following
methods:
- Welding with covered electrodes (SMAW)
- Gas shielded arc welding such as GTAW (TIG), plasma, GMAW (MIG) and
FCW.
- Submerged-arc welding (SAW)
- Post weld heat treatment is not normally necessary. In cases where
heat treatment is considered, for example for stress relieving,
this should be carried out at 1020-1070℃.
