Ipuleti lensimbi engagqwali ngokuvamile liyigama elijwayelekile lepuleti lensimbi engagqwali kanye nepuleti lensimbi elingamelana ne-asidi. Njengoba laqala ekuqaleni kwaleli khulu leminyaka, ukuthuthukiswa kwepuleti lensimbi engagqwali kubeke isisekelo esibalulekile sezinto zobuchwepheshe sokuthuthukiswa kwentuthuko yesimanje yezimboni kanye nesayensi kanye nobuchwepheshe. Kunezinhlobo eziningi zamapuleti ensimbi engagqwali anezakhiwo ezahlukene, futhi kancane kancane akhe izigaba eziningana enkambisweni yokuthuthukiswa. Ngokusho kwesakhiwo, lihlukaniswe ngezigaba ezine: ipuleti lensimbi engagqwali le-austenitic, ipuleti lensimbi engagqwali le-martensitic (kufaka phakathi ipuleti lensimbi engagqwali eliqinisayo), ipuleti lensimbi engagqwali le-ferritic, kanye nepuleti lensimbi engagqwali le-austenitic ferritic duplex. Ngokusho kokwakheka kwamakhemikhali okuyinhloko kwepuleti lensimbi noma ezinye izinto eziphawulekayo epuletini lensimbi ukuze kuhlukaniswe, kuhlukaniswe ipuleti lensimbi engagqwali le-chromium, ipuleti lensimbi engagqwali le-chromium nickel, ipuleti lensimbi engagqwali le-chromium nickel molybdenum kanye nepuleti lensimbi engagqwali le-low carbon, ipuleti lensimbi engagqwali le-high molybdenum, ipuleti lensimbi engagqwali elihlanzekile kakhulu nokunye. Ngokwezimpawu zokusebenza kanye nokusetshenziswa kwepuleti lensimbi, lihlukaniswe ipuleti lensimbi engagqwali elimelana ne-nitric acid, ipuleti lensimbi engagqwali elimelana ne-sulfuric acid, ipuleti lensimbi engagqwali elifaka imigodi, ipuleti lensimbi engagqwali elimelana nokugqwala okucindezelekile, ipuleti lensimbi engagqwali elinamandla aphezulu njalo njalo. Ngokwezimpawu zokusebenza kwepuleti lensimbi, lihlukaniswe ipuleti lensimbi engagqwali elinokushisa okuphansi, ipuleti lensimbi engagqwali elingenamagnetic, ipuleti lensimbi engagqwali elilula ukusika, ipuleti lensimbi engagqwali elipulasitiki kakhulu. Indlela yokuhlela evame ukusetshenziswa ihlukaniswa ngokwezimpawu zesakhiwo sepuleti lensimbi kanye nezici zokwakheka kwamakhemikhali kwepuleti lensimbi kanye nokuhlanganiswa kwezindlela ezimbili. Ngokuvamile lihlukaniswe ipuleti lensimbi engagqwali le-martensitic, ipuleti lensimbi engagqwali le-ferritic, ipuleti lensimbi engagqwali le-austenitic, ipuleti lensimbi engagqwali eliphindwe kabili kanye nepuleti lensimbi engagqwali lohlobo lwemvula noma lihlukaniswe ipuleti lensimbi engagqwali le-chromium kanye nepuleti lensimbi engagqwali le-nickel izigaba ezimbili. Ukusetshenziswa okujwayelekile: imishini ye-pulp kanye nephepha I-heat exchanger, imishini yemishini, imishini yokudaya, imishini yokuwasha amafilimu, amapayipi, izinto zokwakha zangaphandle zasogwini, njll.
Ubuso bepuleti lensimbi engagqwali bubushelelezi, bunobucwebe obuphezulu, ukuqina kanye namandla okusebenza, futhi bumelana ne-asidi, igesi ye-alkaline, isixazululo kanye nokunye ukugqwala kwemidiya. Kuyinsimbi ye-alloy okungelula ukuyigqwala, kodwa ayinayo nhlobo ukugqwala.
