Uma ukhetha ibanga lensimbi engagqwali (SS) yohlelo lwakho lokusebenza noma i-prototype, kubalulekile ukucabangela ukuthi izakhiwo kazibuthe ziyadingeka yini.Ukuze wenze isinqumo esinolwazi, kubalulekile ukubamba izici ezinquma ukuthi izinga lensimbi engagqwali liwuzibuthe noma cha.
Izinsimbi ezingagqwali ama-alloys asekelwe ku-iron adume ngokumelana nokugqwala kwawo okuhle kakhulu.Kunezinhlobo ezahlukene zezinsimbi ezingenasici, nezigaba eziyinhloko ezithi i-austenitic (isb, 304H20RW, 304F10250X010SL) kanye ne-ferritic (evame ukusetshenziswa ekusetshenzisweni kwezimoto, i-kitchenware, nemishini yezimboni).Lezi zigaba zinezakhi zamakhemikhali ezihlukile, okuholela ekuziphatheni kwazo okungafaniyo kazibuthe.Izinsimbi ezingenasici ze-Ferritic zivame ukuba kazibuthe, kuyilapho izinsimbi ezingenasici ze-austenitic zingekho.Uzibuthe wensimbi engagqwali ye-ferritic uvela ezintweni ezimbili ezibalulekile: okuqukethwe kwayo kwensimbi ephezulu kanye nokuhlelwa kwayo kwesakhiwo.
Ushintsho lusuka ku-Non-Magnetic kuya ku-Magnetic Phase ku-Stainless Steel
Kokubili304kanye nezinsimbi ezingagqwali ezingu-316 ziwela ngaphansi kwesigaba se-austenitic, okusho ukuthi uma zipholile, insimbi igcina ifomu layo le-austenite (i-gamma iron), okuyisigaba esingenazibuthe.Izigaba ezihlukahlukene zensimbi eqinile zihambisana nezinhlaka zekristalu ezihlukile.Kwamanye ama-alloys ensimbi, lesi sigaba sensimbi enezinga eliphezulu lokushisa sishintsha sibe yisigaba sikazibuthe ngesikhathi sokupholisa.Kodwa-ke, ukuba khona kwe-nickel kuma-alloys ensimbi engagqwali kuvimbela lokhu kuguquka kwesigaba njengoba ingxubevange iphola ekamelweni lokushisa.Ngenxa yalokho, insimbi engagqwali ibonisa ukuthambekela kukazibuthe okuphakeme kancane kunezinto ezingezona uzibuthe ngokuphelele, nakuba isalokhu ingaphansi kwalokho ngokuvamile okubhekwa njengozibuthe.
Kubalulekile ukuqaphela ukuthi akufanele ngempela ulindele ukukala ukuthambekela okuphansi kazibuthe kulo lonke ucezu lwensimbi engagqwali engu-304 noma engu-316 ohlangana nayo.Noma iyiphi inqubo ekwazi ukuguqula isakhiwo sekristalu yensimbi engagqwali ingabangela i-austenite ukuthi iguqule ibe yi-ferromagnetic martensite noma izinhlobo ze-ferrite zensimbi.Izinqubo ezinjalo zihlanganisa ukusebenza okubandayo kanye nokushisela.Ukwengeza, i-austenite ingashintsha ngokuzenzekelayo ibe i-martensite emazingeni okushisa aphansi.Ukwengeza ubunkimbinkimbi, izakhiwo kazibuthe zalezi zingxubevange zithonywa ukubunjwa kwazo.Ngisho nangaphakathi kwebanga elivumelekile lokuhluka kokuqukethwe kwe-nickel ne-chromium, umehluko obonakalayo wezakhiwo kazibuthe ungabonwa ku-alloy ethile.
Ukucatshangelwa Okusebenzayo Kokukhipha Izinhlayiya Zensimbi Engagqwali
Kokubili 304 kanye316 insimbi engagqwalibonisa izici ze-paramagnetic.Ngakho-ke, izinhlayiya ezincane, njengezimbulunga ezinobubanzi obusukela ku-0.1 kuye ku-3mm, zingadonselwa kuzihlukanisi ezinamandla zikazibuthe ezibekwe ngendlela ehlelekile ngaphakathi kokugeleza komkhiqizo.Ngokuya ngesisindo sazo futhi, okubaluleke nakakhulu, isisindo sazo esihlobene namandla okukhanga kazibuthe, lezi zinhlayiya ezincane zizonamathela kumagnet ngesikhathi senqubo yokukhiqiza.
Kamuva, lezi zinhlayiya zingasuswa ngokuphumelelayo phakathi nemisebenzi yokuhlanza kazibuthe.Ngokusekelwe ekuqapheleni kwethu okungokoqobo, sithole ukuthi izinhlayiya zensimbi engagqwali ezingu-304 cishe zizogcinwa ekugelezeni uma kuqhathaniswa nezinhlayiya zensimbi engagqwali ezingu-316.Lokhu kungenxa yemvelo ephakeme kancane kazibuthe yensimbi engagqwali engu-304, okuyenza iphendule kakhulu kumasu okuhlukanisa kazibuthe.
