Product Description:

UNS S31803 Stainless steel plate

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.

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
