XINFUTIAN METAL PRODUCTS CO., LTD now includes Duplex 2205
(UNS S32205 / S31803), in sheet, sheet coil, plate, plate coil,
round bar, processed flat bar and tubular products. Duplex 2205 is
ideally suited for high-pressure and highly corrosive environments.
Products Details
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.

Corrosion Resitance
1. Due to its high chromium, molybdenum, and nitrogen content,
Duplex 2205 demonstrates superior corrosion resistant properties to
316 and 316L in most environments
2. Chromium, molybdenum, and nitrogen content also provide high
resistance to pitting and crevice corrosion, even in oxidizing and
acidic solutions
3. Resistant to chloride stress corrosion cracking and temperatures
of up to about 302°F (150°C)
4. The presence of ferrite provides for good performance of Duplex
2205 in caustic environments
Heat Resitance
1.Similar to other duplex stainless steels, Duplex 2205 has good
oxidation resistance at high temperatures
2. 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)
Applications
1). Chemical processing, transport and storage – pressure vessels,
tanks, piping, and heat exchangers
2). Oil and gas exploration and processing equipment – piping,
tubing, and heat exchangers
3). Marine and other high chloride environments
4). Effluent scrubbing systems
5). Pulp and paper industry – digesters, bleaching equipment, and
stock-handling systems
6). Cargo tanks for ships and trucks
7). Food processing equipment
8). Biofuels plants
