General Properties
Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3%
molybdenum, 5 to 6% nickel alloyed stainless steel. It 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. It also demonstrates good fatigue strength,
as well as outstanding resistance to stress corrosion cracking,
crevice, pitting, erosion, and general corrosion in severe
environments.
Applications:
Chemical processing, transport and storage – pressure vessels,
tanks, piping, and heat exchangers
Oil and gas exploration and processing equipment – piping, tubing,
and heat exchangers
Marine and other high chloride environments
Effluent scrubbing systems
Pulp and paper industry – digesters, bleaching equipment, and
stock-handling systems
Cargo tanks for ships and trucks
Food processing equipment
Biofuels plants
Standards:
ASTM/ASME: A240 UNS S32205/S31803
EURONORM: 1.4462 X2CrNiMoN 22.5.3
AFNOR: Z3 CrNi 22.05 AZ
DIN: W.Nr 1.4462
Corrosion Resistance:
Due to its high chromium, molybdenum, and nitrogen content, Duplex
2205 demonstrates superior corrosion resistant properties to 316
and 316L in most environments
Chromium, molybdenum, and nitrogen content also provide high
resistance to pitting and crevice corrosion, even in oxidizing and
acidic solutions
Resistant to chloride stress corrosion cracking and temperatures of
up to about 302°F (150°C)
The presence of ferrite provides for good performance of Duplex
2205 in caustic environments
Heat Resistance:
Similar to other duplex stainless steels, Duplex 2205 has good
oxidation resistance at high temperatures
Subject to embrittlement when exposed to temperatures above 572°F
(300°C) even when exposed for short periods of time; Duplex 2205 is
therefore not recommended for use above 572°F (300°C)
