Izakhiwo Ezijwayelekile
I-alloy 2205 duplex steel stainless steel plate ingu-22% Chromium, 3% Molybdenum, 5-6% Nickel nitrogen alloyed duplex stainless steel plate enezindawo zokumelana nokugqwala okuphezulu okujwayelekile, okwasendaweni kanye nengcindezi ngaphezu kwamandla aphezulu kanye nokuqina komthelela omuhle kakhulu.
2205 insimbi engagqwali coiled tubing
I-alloy 2205 duplex stainless steel plate ihlinzeka ukumelana nokugqwala kwe-pitting kanye ne-crevice ephakeme kuno-316L noma 317L ama-austenitic stainless steels cishe kuyo yonke imidiya egqwalayo.Iphinde ibe nokugqwala okuphezulu kanye nezindawo zokukhathala kokuguguleka kanye nokunwebeka okuphansi kokushisa kanye nokuhanjiswa kwe-thermal okuphezulu kune-austenitic.
Amandla okukhiqiza cishe aphindwe kabili kunama-austenitic stainless steels.Lokhu kuvumela umklami ukuthi onge isisindo futhi kwenza ingxubevange ibe nezindleko eziningi uma iqhathaniswa no-316L noma 317L.
2205 insimbi engagqwali coiled tubing
I-alloy 2205 duplex stainless steel plate ifaneleka ngokukhethekile izinhlelo zokusebenza ezimboza izinga lokushisa -50°F/+600°F.Amazinga okushisa angaphandle kwalolu banga angacatshangelwa kodwa adinga imikhawulo ethile, ikakhulukazi ezakhiweni ezishiselwe.

Ukumelana Nokugqwala
Ukugqwala Okujwayelekile
Ngenxa yokuqukethwe kwayo okuphezulu kwe-chromium (22%), i-molybdenum (3%), kanye ne-nitrogen (0.18%), izakhiwo zokumelana nokugqwala kwe-2205 duplex stainless steel plate ziphakeme kune-316L noma 317L ezindaweni eziningi.
Ukumelana Nokugqwala Kwendawo
I-chromium, i-molybdenum, ne-nitrogen ku-2205 duplex stainless steel plate iphinde inikeze ukumelana okuhle nokugqwala kwe-pitting kanye nokugqwala ngisho nasezixazululweni ezixube kakhulu nezine-acidic.
I-Isocorrosion Curves 4 mpy (0.1 mm/unyaka), kusisombululo se-sulfuric acid esiqukethe 2000 ppm
I-Stress Corrosion Resistance
I-duplex microstructure yaziwa ngokuthuthukisa ukumelana nokuqhekeka kokugqwala kwengcindezi yezinsimbi ezingenasici.
I-Chloride stress corrosion cracking of austenitic stainless steels kungenzeka lapho izimo ezidingekayo zezinga lokushisa, ingcindezi eqinile, umoya-mpilo, nama-chloride zikhona.Njengoba lezi zimo zingalawuleki kalula, ukuqhekeka kokugqwala kwengcindezi kuvame ukuba isithiyo ekusebenziseni u-304L, 316L, noma 317L.

I-Corrosion Fatigue Resistence
I-alloy 2205 duplex ipuleti lensimbi engagqwali ihlanganisa amandla aphezulu kanye nokumelana nokugqwala okuphezulu ukukhiqiza amandla okukhathala okugqwala okuphezulu.Izicelo lapho okokusebenza okucutshungulwayo kukhonjelwe kukho kokubili indawo egqwala kakhulu kanye nokulayisha ngamabhayisikili zingazuza kuzakhiwo ze-2205 duplex stainless steel plate.
