Uma ukhetha ibanga lensimbi engagqwali (SS) lokusetshenziswa kwakho noma uhlobo lweprototype, kubalulekile ukucabangela ukuthi ngabe kudingeka yini izakhiwo zikamazibuthe. Ukuze wenze isinqumo esinolwazi, kubalulekile ukuqonda izici ezinquma ukuthi ibanga lensimbi engagqwali liyimagnethi noma cha.
Izinsimbi ezingagqwali ziyi-alloys ezisekelwe ensimbini ezidumile ngokumelana kwazo okuhle kakhulu nokugqwala. Kunezinhlobo ezahlukene zezinsimbi ezingagqwali, kanti izigaba eziyinhloko ziyi-austenitic (isb., 304H20RW, 304F10250X010SL) kanye ne-ferritic (evame ukusetshenziswa ezisetshenziswa ezimotweni, ezitsheni zasekhishini, kanye nasemishinini yezimboni). Lezi zigaba zinezakhi zamakhemikhali ezihlukile, okuholela ekuziphatheni kwazo okuhlukile kwe-magnetic. Izinsimbi ezingagqwali ze-Ferritic zivame ukuba ne-magnetic, kanti izinsimbi ezingagqwali ze-austenitic azinjalo. I-magnetism yensimbi engagqwali ye-ferritic ivela ezintweni ezimbili ezibalulekile: okuqukethwe kwayo okuphezulu kwensimbi kanye nokuhlelwa kwayo kwesakhiwo.
Ukuguquka kusuka ku-Non-Magnetic kuya ku-Magnetic Phases ku-Stainless Steel
Kokubili304kanye nezinsimbi ezingagqwali ezingu-316 ziwela ngaphansi kwesigaba se-austenitic, okusho ukuthi uma zipholile, insimbi igcina isimo sayo se-austenite (i-gamma iron), isigaba esingeyona i-magnetic. Izigaba ezahlukahlukene zensimbi eqinile zihambisana nezakhiwo zekristalu ezihlukile. Kwezinye izinhlobo zensimbi, lesi sigaba sensimbi esishisa kakhulu siguquka sibe yisigaba se-magnetic ngesikhathi sokupholisa. Kodwa-ke, ukuba khona kwe-nickel kuma-alloy ensimbi engagqwali kuvimbela lokhu kuguquka kwesigaba njengoba i-alloy iphola iye ekushiseni kwegumbi. Ngenxa yalokho, insimbi engagqwali ibonisa ukuthambekela okuphezulu kancane kunamandla kamagnetic kunezinto ezingeyona i-magnetic ngokuphelele, yize isalokhu ingaphansi kakhulu kwalokho okuvame ukubhekwa njenge-magnetic.
Kubalulekile ukuqaphela ukuthi akufanele ngempela ulindele ukukala ukuthambekela okuphansi kangaka kwe-magnetic kuzo zonke izingxenye zensimbi engagqwali engu-304 noma engu-316 ohlangana nazo. Noma iyiphi inqubo ekwazi ukushintsha isakhiwo sekristalu sensimbi engagqwali ingabangela ukuthi i-austenite iguquke ibe yi-ferromagnetic martensite noma izinhlobo ze-ferrite zensimbi. Izinqubo ezinjalo zifaka phakathi ukusebenza okubandayo kanye nokushisela. Ngaphezu kwalokho, i-austenite ingaguquka ngokuzenzakalelayo ibe yi-martensite emazingeni okushisa aphansi. Ukuze wengeze ubunzima, izakhiwo ze-magnetic zalezi zingxube zithonywa ukwakheka kwazo. Ngisho nangaphakathi kwebanga elivumelekile lokwehluka kokuqukethwe kwe-nickel ne-chromium, umehluko obonakalayo ezimpahleni ze-magnetic ungabonakala ku-alloy ethile.
Izinto Eziwusizo Zokucatshangelwa Zokususa Izinhlayiya Zensimbi Engagqwali
Kokubili okungu-304 kanyeInsimbi engagqwali engu-316zikhombisa izici ze-paramagnetic. Ngenxa yalokho, izinhlayiya ezincane, njengezimbulunga ezinobubanzi obusukela cishe ku-0.1 kuya ku-3mm, zingadonselwa kubahlukanisi bamagnetic abanamandla ababekwe ngendlela efanele ngaphakathi komfudlana womkhiqizo. Kuye ngesisindo sazo, futhi okubaluleke kakhulu, isisindo sazo maqondana namandla okukhanga kwamagnetic, lezi zinhlayiya ezincane zizonamathela kumagnet ngesikhathi senqubo yokukhiqiza.
Ngemva kwalokho, lezi zinhlayiya zingasuswa ngempumelelo ngesikhathi sokuhlanzwa okuvamile kwe-magnet. Ngokusekelwe ekubonweni kwethu okusebenzayo, sithole ukuthi izinhlayiya zensimbi engagqwali ezingu-304 cishe zigcinwa ekugelezeni uma kuqhathaniswa nezinhlayiya zensimbi engagqwali ezingu-316. Lokhu kubangelwa kakhulu yimvelo yamagnetic ephakeme kancane yensimbi engagqwali engu-304, okwenza isabela kangcono kumasu okuhlukanisa i-magnetic.
