Umehluko omkhulu phakathi kwe-duplex 2205 kanye ne-316 yensimbi engagqwali ichazwe ngezansi: 1. Ukwakheka: I-Duplex 2205 iwuhlobo lwensimbi engagqwali eyi-duplex, eyinhlanganisela ye-austenitic stainless steel kanye ne-ferritic stainless steel.IquketheUmehluko omkhulu phakathi kwe-duplex 2205 kanye ne-316 yensimbi engagqwali ichazwe ngezansi: 1. Ukwakheka: I-Duplex 2205 iwuhlobo lwensimbi engagqwali eyi-duplex, eyinhlanganisela ye-austenitic stainless steel kanye ne-ferritic stainless steel.Iqukethe cishe u-22% we-chromium, u-5% we-nickel, u-3% we-molybdenum kanye no-4.5% we-nitrogen.Ngakolunye uhlangothi, insimbi engagqwali engu-316 iyingxubevange yensimbi engagqwali ye-austenitic ehlanganisa cishe u-16-18% we-chromium, i-10-14% ye-nickel, i-2-3% ye-molybdenum, kanye nenani elincane lezinye izakhi ezifana ne-carbon, manganese, ne-silicon.2. Ukumelana nokugqwala: Uma kuqhathaniswa nensimbi engagqwali engu-316, i-duplex 2205 inokumelana nokugqwala okungcono, ikakhulukazi endaweni ecebile nge-chloride.Ikhuphule ukumelana ne-pitting, ukugqwala kwemifantu kanye nokuqhekeka kokugqwala kwengcindezi.Lokhu kwenza i-duplex steel 2205 ilungele ukusetshenziswa ezimbonini zasolwandle, zikawoyela negesi, nezimboni zamakhemikhali.Insimbi engagqwali engu-316 nayo ikhombisa ukumelana nokugqwala okuhle, kodwa kungenzeka ingasebenzi njenge-duplex 2205 ezindaweni ezine-chloride.3. Amandla: Amandla e-duplex 2205 aphakeme kunalawo ensimbi engagqwali engu-316.Isakhiwo sayo se-biphasic sinomthelela ezintweni zayo ezinhle kakhulu zemishini, njengokushuba okuphezulu namandla esivuno.Le nzuzo yamandla yenza i-duplex 2205 ilungele izinhlelo zokusebenza ezidinga amandla aphezulu nokwethembeka.4. Inani: I-Duplex 2205 ngokuvamile ibiza kakhulu kune-316 yensimbi engagqwali ngenxa yezindleko eziphezulu zempahla kanye nenqubo yokukhiqiza eyinkimbinkimbi.Ukwengezwa kwezakhi ze-alloying ezifana ne-nitrogen ne-molybdenum kwandisa izindleko zokukhiqiza.Kodwa-ke, umehluko wentengo ungahluka ngokuya ngezimo zemakethe nezinye izici.Kafushane, uma kuqhathaniswa nensimbi engagqwali engu-316, i-duplex 2205 inokumelana nokugqwala okuhle kakhulu, amandla aphezulu kanye nokushisela okuhle.Nokho, ukukhetha phakathi kwalokhu kokubili kuzoncika ezidingweni ezithile zohlelo lokusebenza nokucatshangelwa kwesabelomali cishe okungama-22% e-chromium, ama-5% e-nickel, ama-3% e-molybdenum kanye nama-4.5% e-nitrogen.Ngakolunye uhlangothi, insimbi engagqwali engu-316 iyingxubevange yensimbi engagqwali ye-austenitic ehlanganisa cishe u-16-18% we-chromium, i-10-14% ye-nickel, i-2-3% ye-molybdenum, kanye nenani elincane lezinye izakhi ezifana ne-carbon, manganese, ne-silicon.2. Ukumelana nokugqwala: Uma kuqhathaniswa nensimbi engagqwali engu-316, i-duplex 2205 inokumelana nokugqwala okungcono, ikakhulukazi endaweni ecebile nge-chloride.Ikhuphule ukumelana ne-pitting, ukugqwala kwemifantu kanye nokuqhekeka kokugqwala kwengcindezi.Lokhu kwenza i-duplex steel 2205 ilungele ukusetshenziswa ezimbonini zasolwandle, zikawoyela negesi, nezimboni zamakhemikhali.Insimbi engagqwali engu-316 nayo ikhombisa ukumelana nokugqwala okuhle, kodwa kungenzeka ingasebenzi njenge-duplex 2205 ezindaweni ezine-chloride.3.
