I-S31803 Insimbi Engagqwali
Insimbi Engagqwali i-S31803 iyizinga lensimbi engenasici elaziwa kabanzi elihlanganisa izinzuzo ze-austenitic ne-ferritic stainless steels, enikeza ibhalansi ehlukile yamandla aphezulu, ukumelana nokugqwala okuphakeme, kanye nokushisela okuhle. Le duplex alloy iyingxenye yochungechunge lwe-2205, olubonakala cishe nge-50/50 austenitic{5}}i-ferritic microstructure, eletha ukusebenza okuthuthukisiwe ezindaweni ezinolaka uma kuqhathaniswa namamaki amaningi ajwayelekile e-austenitic.

Isici
I-S31803, -isigaba sensimbi engagqwali ekabili, ikweleta isakhiwo nezici zayo ngokwakhiwa kwamakhemikhali okuklanywe ngokunembile. I-Chromium (21-23%) yenza isendlalelo se-oxide esivikelayo sokumelana nokugqwala, i-nickel (4.5-6.5%) isimamisa isigaba se-austenitic, futhi i-molybdenum (2.5-3.5%) ithuthukisa ukumelana nokugqwala kwe-pitting kanye nokuqhekeka, ikakhulukazi ezimeni ezicebile nge-chloride. I-nitrogen (0.08-0.20%) iqinisa isigaba se-austenitic, kuyilapho i-carbon, i-manganese, i-silicon, i-phosphorus, nesulfure ilawulwa ukuze kugcinwe ibhalansi ye-microstructural.
Ngokwemishini, i-S31803 ihamba phambili ngamandla aphansi aqinile angama-620 MPa futhi ikhiqiza amandla angama-450 MPa, acishe aphindwe kabili kunama-304 noma angama-316, nokho igcina ubude obungama-25% bokwenziwa. Amandla ayo aphezulu-kuya{8}}isilinganiso sesisindo sifanelana nesisindo-izinhlelo zokusebenza ezizwelayo.
Ukumelana nokugqwala kuyinqaba ye-S31803. Nge-PREN engu-32-36, imelana nokugqwala okuvamile, umgodi, kanye nemifantu emanzini olwandle, ugwadule, namakhemikhali ezimboni kangcono kuno-316.
Izinhlelo zokusebenza
Unjiniyela Wasolwandle:Imishini yokukhipha usawoti emanzini olwandle, amaphampu/amavalvu olwandle, izakhiwo zamapulatifomu angasogwini
Izisetshenziswa ze-Petrochemical:Amapayipi okuhluza uwoyela, amathangi okugcina, izishintshisi zokushisa (zimelana nokugqwala kwe-H₂S/CO₂)
Ukuvikelwa Kwemvelo:Amasistimu okuhlanza amanzi angcolile, amayunithi e-flue gas desulfurization
Imboni Yamakhemikhali:Iziqukathi{0}}eziphakeme ze-chloride ion medium (isb., okokusebenza kokuxubha)
Amashadi ashisayo: s31803 insimbi engagqwali, China s31803 abakhiqizi bensimbi engagqwali, abahlinzeki, imboni
