Lapho ukhetha ibanga lensimbi engagqwali (i-SS) yesicelo sakho noma i-prototype, kubalulekile ukubheka ukuthi ngabe izakhiwo zenkatha ziyadingeka yini. Ukwenza isinqumo esinolwazi, kubalulekile ukuqonda izici ezinquma ukuthi ibanga lensimbi elingagqwali lingamabala noma cha.
Ama-steres angenasici ane-alloys esekwe ngensimbi edume ngokumelana kwawo okuhle kakhulu. Kunezinhlobo ezahlukahlukene zensimbi engagqwali, nezigaba eziyisisekelo eziba yi-auntenitic (isib. Lezi zigaba zinezinto ezihlukile zamakhemikhali, okuholela ekuphatheni kwazo kwamandla kazibuthe. Ama-welitic ama-stainless angenasici avame ukuba yizinkawu, kanti ama-auntenitutic steress awekho. Ubude be-Ferritic wensimbi engenasici buqhamuka ezintweni ezimbili ezibalulekile: okuqukethwe kwayo okuphezulu kwensimbi kanye nokuhlelwa kwalo kwesakhiwo.
Ukuguqulwa kusuka ku-non-magnetic ngezigaba zama-magnetic ngensimbi engenasici
Kokubili30futhi ama-316 ama-steanless awela ngaphansi kwesigaba se-auntenitic, okusho ukuthi lapho bepholile, i-iron igcina ifomu layo le-Auucen (Gamma Iron), isigaba esingewona ama-magnetic. Izigaba ezahlukahlukene zensimbi eqinile zihambelana nezinhlaka zekristali ezihlukile. Kwamanye ama-alloys ensimbi, lesi sigaba sensimbi esishisa kakhulu siguqula sibe yisigaba sabazikazi ngesikhathi sokupholisa. Kodwa-ke, ukuba khona kwe-nickel kuma-alloys wensimbi engagqwali kuvimbela lolu shintsho lwesigaba njengoba i-alloy ipholile ekushiseni kwegumbi. Ngenxa yalokhu, insimbi engagqwali ibonisa amandla aphezulu kazibuthe aphezulu kunezinto ezingezinhle ngokuphelele, yize zisalokhu zisengezansi kahle lokho okucatshangwa ukuthi kucatshangelwa ukuthi zithathwa njengezibuthe.
Kubalulekile ukuqaphela ukuthi akufanele ulindele ukukala ukukala okuphansi kazibuthe kuzo zonke izingcezu ezingama-304 noma ezingama-316 zensimbi engagqwali ohlangabezana nazo. Noma iyiphi inqubo ekwazi ukuguqula ukwakheka kwe-crystal yensimbi engenacala ingadala i-Aupen. Izinqubo ezinjalo zifaka ukusebenza okubandayo nokufudumeza. Ngokwengeziwe, i-Auucenite ingaguqula ngokungazelele ibe ngumfemuli emazingeni okushisa aphansi. Ukwengeza ubunzima, izakhiwo zikazibuthe zalezi ze-alloys zithonywa ukwakheka kwazo. Noma kungakapheli amabanga avumelekile okuhlukahluka ku-nickel kanye ne-chromium okuqukethwe, umehluko obonakalayo kwizakhiwo zamazibuthe ungabhekwa nge-alloy ethile.
Ukucatshangelwa okusebenzayo kokususa izinhlayiya zensimbi ezingenasici
Bobabili 304 futhi316 insimbi engagqwalibonisa izici ze-paramagnetic. Ngenxa yalokho, izinhlayiya ezincane, njengezinhlaka ezinama-diameters zisukela cishe zingu-0,1 ziye ku-3mm, zingadonswa kuma-magnetic anamandla abekelwe amasu wokusakazwa komkhiqizo. Ngokuya ngesisindo sabo futhi, okubaluleke kakhulu, isisindo sabo esihlobene namandla okukhanga kazibuthe, lezi zinhlayiya ezincane zizonamathela kuma-magnets ngesikhathi sokukhiqiza.
Kamuva, lezi zinhlayiya zingasuswa ngempumelelo phakathi nemisebenzi yokuhlanza izibuthe ezijwayelekile. Ngokusekelwe ekubukeni kwethu okusebenzayo, sithole ukuthi izinhlayiya zensimbi ezingama-304 ezingenasici kungenzeka zigcinwe ngokugeleza uma kuqhathaniswa nezinhlayiya zensimbi ezingama-316. Lokhu kufakazelwe ngokuyinhloko kwimvelo ephezulu kazibuthe engama-304 insimbi engagqwali, eyenza iphendule ngokwengeziwe amasu okuhlukanisa kazibuthe.
