Ukubuka konke kwe-2205 Duplex
I-Duplex 2205 iyi-nitrogen ethuthukisiweinsimbi engagqwali duplexeyasungulwa ukuze ilwe nezinkinga zokugqwala ezivamile ezihlangatshezwane nochungechunge lwezinsimbi ezingenasici ezingama-300.I-"Duplex" ichaza umndeni wezinsimbi ezingenasici ezingezona i-austenitic ngokugcwele, njenge-304 engenasici, noma i-ferritic emsulwa, njenge-430 engenabala.Isakhiwo se-2205 duplex stainless steel siqukethe amachibi ama-austenite azungezwe isigaba se-ferrite esiqhubekayo.Esimeni esifakiwe, i-2205 iqukethe cishe i-40-50% ye-ferrite.Okuvame ukubizwa ngokuthi yizinga lehhashi lomsebenzi, i-2205 iyibanga elisetshenziswa kakhulu emndenini we-duplex wezinsimbi ezingenasici.

Ukusetshenziswa kwe-2205 Duplex steel stainless kufanele kukhawulelwe emazingeni okushisa angaphansi kuka-600° F. Ukuchayeka okunwetshiwe kwezinga lokushisa kungase kuthobise i-2205 stainless.

Ukumelana Nokugqwala
2205 insimbi engagqwali eyi-duplex iyikhambi elibiza izindleko ezinhlelweni eziningi lapho uchungechunge lwama-stainless steels angama-300 lusengozini yokuqhekeka kokugqwala kokucindezeleka kwe-chloride.Ukuqhekeka kokugqwala kwengcindezi kwenzeka lapho izinsimbi ezingenasici zingaphansi kwengcindezi eqinile, ngenkathi zithinta izixazululo eziqukethe ama-chloride.Ukwenyuka kwamazinga okushisa nakho kukhulisa ukuthambekela kwezinsimbi ezingenasici ukuze kugcizelele ukuqhekeka kokugqwala.
Inhlanganisela ye-chromium, i-molybdenum ne-nitrogen idlulisa ukumelana okuhle kwe-2205 ku-chloride pitting kanye nokugqwala kwe-crevice.Lokhu kumelana kubaluleke kakhulu ezinsizeni ezifana nezindawo zasolwandle, amanzi anosawoti, ukusebenza kwe-bleaching, amasistimu amanzi avaliwe kanye nezinye izinhlelo zokusebenza zokucubungula ukudla.I-chromium ephezulu, i-molybdenum ne-nitrogen okuqukethwe kuka-2205 kunikeza ukumelana nokugqwala okuphakeme kunezinsimbi ezingenasici ezivamile, njengokuthi, 316L kanye no-317L ezindaweni eziningi.
