Cold/Hot Rolled ASTM S2205 Seamless Super Duplex 2507 EU 3.2 Certification

2507 is a super-duplex (austenitic-ferritic) stainless steel for service in highly corrosive conditions. The grade is characterized by:Excellent resistance to stress corrosion cracking (SCC) in chloride-bearing environments Excellent resistance to pitting and crevice corrosion High resistance to general corrosion Very high mechanical strength Physical properties that offer design advantages High resistance to erosion corrosion and corrosion fatigue Good weldability.

Product Details

Typical applications for 2507Oil and gas exploration

and productionChloride-containing environments such as seawater handling and process systems. Hydraulic and process fluid tubes in umbilicalsSeawater cooling

Tubing for heat exchangers in refineries, chemical industries, process industries and other industries using seawater or chlorinated seawater as coolantSalt evaporationEvaporator tubing for production of corrosive salts, e.g. chlorides, sulfates and carbonatesDesalination plants

Pressure vessels for reverse osmosis units, tube and pipe for seawater transport, heat exchanger tubingGeothermal wells
Heat exchangers in geothermal exploitation units, systems exposed to geothermal or high salinity brines, tubing and casing for productionOil refining and petrochemical and gas processingTubes and pipes where the process environment contains a high amount of chlorides, or is contaminated with hydrochloric acidPulp and paper production

Material for chloride-containing bleaching environmentsChemical processing
Organic acid plants, also when process solutions are contaminated with e.g. chloridesMechanical components requiring high strength

Propeller shafts and other products subjected to high mechanical load in seawater and other chloride-containing environmentsDesulfurization unitsAs reheater tubes in flue gas desulfurization systems. The good mechanical and corrosion properties make 2507 an economical choice in many applications by reducing the life cycle cost of equipment.
