General Properties
Alloy 2205 duplex Stainless simbi ndiro i22% Chromium, 3% Molybdenum, 5-6% Nickel nitrogen alloyed duplex Stainless simbi ndiro ine yakakwira general, localized uye stress corrosion resistance properties.
2205 simbi isina tsvina yakasungirirwa tubing
Alloy 2205 duplex stainless simbi ndiro inopa pitting uye crevice corrosion resistance inodarika 316L kana 317L austenitic stainless steels mune dzinenge dzese corrosion media.Iyo zvakare ine yakakwira corrosion uye erosion kuneta zvivakwa pamwe nekudzikira kwekupisa kwekuwedzera uye yakakwirira yekupisa conductivity pane austenitic.
Simba regoho rinenge rakapetwa kaviri kune austenitic stainless steels.Izvi zvinobvumira mugadziri kuchengetedza huremu uye anoita kuti alloy awedzere mutengo kukwikwidza kana achienzaniswa ne316L kana 317L.
2205 simbi isina tsvina yakasungirirwa tubing
Alloy 2205 duplex stainless steel plate inonyanya kukodzera maapplication anovhara -50°F/+600°F tembiricha renji.Tembiricha dziri kunze kwerudzi urwu dzinogona kutariswa asi dzinoda zvirambidzo, kunyanya kune zvivakwa zvakasungwa.

Corrosion Resistance
General Corrosion
Nekuda kweiyo yakakwira chromium (22%), molybdenum (3%), uye nitrogen (0.18%), iyo corrosion resistance properties ye2205 duplex stainless steel plate yakakwirira kudarika ye316L kana 317L munzvimbo dzakawanda.
Localized Corrosion Resistance
Iyo chromium, molybdenum, uye nitrogen mu2205 duplex stainless steel plate inopawo kupikisa kwakanakisa kugomba uye kukoromoka kwegomba kunyangwe mune oxidizing uye acidic mhinduro.
Isocorrosion Curves 4 mpy (0.1 mm/gore), mune sulfuric acid solution ine 2000 ppm
Stress Corrosion Resistance
Iyo duplex microstructure inozivikanwa kuvandudza kushushikana kwecorrosion kupaza kuramba kwesimbi isina tsvina.
Chloride stress corrosion cracking yeaustenitic stainless steels inogona kuitika kana mamiriro anodiwa ekupisa, tensile stress, oxygen, uye chlorides aripo.Sezvo mamiriro aya asingadzoreki zviri nyore, kudzvanya kwekuora mwoyo kwagara kuri chipingamupinyi pakushandisa 304L, 316L, kana 317L.
