Inqubo yokukhiqiza ummese wensimbi engagqwali, ifoloko kanye nesipuni esincane sesidlo sakusihlwa yenziwa ngezinqubo eziningi eziyinkimbinkimbi ezifana nokunyathela, ukushisela kanye nokugaya
Izitsha zokudla zensimbi engagqwali zasekhaya zingahlukaniswa zibe yi-201, 430, 304 (18-8) kanye ne-18-10.
Insimbi engagqwali engu-430:
Insimbi + i-chromium engaphezu kuka-12% ingavimbela ukubola okubangelwa yizinto zemvelo. Ibizwa ngokuthi insimbi engagqwali. Ku-JIS, ibizwa ngokuthi ikhodi engu-430, ngakho-ke ibizwa nangokuthi insimbi engagqwali engu-430. Kodwa-ke, insimbi engagqwali engu-430 ayikwazi ukumelana nokubola okubangelwa amakhemikhali emoyeni. Insimbi engagqwali engu-430 ayivame ukusetshenziswa isikhathi esithile, kodwa isazobola (igqwale) ngenxa yezinto ezingezona ezemvelo.
Insimbi engagqwali engu-18-8:
Insimbi + 18% chromium + 8% nickel ingamelana nokushiswa kwamakhemikhali. Le nsimbi engagqwali inguNombolo 304 kukhodi ye-JIS, ngakho-ke ibizwa nangokuthi insimbi engagqwali engu-304.
Insimbi engagqwali engu-18-10:
Kodwa-ke, kunezakhi zamakhemikhali eziningi kakhulu emoyeni, futhi ngisho ne-304 izogqwala kwezinye izindawo ezingcolile kakhulu; Ngakho-ke, eminye imikhiqizo yezinga eliphezulu izokwenziwa nge-nickel engu-10% ukuze ihlale isikhathi eside futhi imelane nokugqwala. Lolu hlobo lwensimbi engagqwali lubizwa ngokuthi insimbi engagqwali engu-18-10. Kweminye imiyalelo yetafula, kunesisho esifana nesithi “ukusebenzisa insimbi engagqwali yezokwelapha esezingeni eliphezulu kakhulu engu-18-10”.
Ngokusho kokuhlaziywa kwesikhungo socwaningo lwedatha, insimbi engagqwali ingahlukaniswa ngezigaba ezintathu: insimbi engagqwali ye-austenitic, insimbi engagqwali ye-ferritic kanye nensimbi engagqwali ye-martensitic. Izingxenye eziyinhloko zensimbi engagqwali yi-iron, i-chromium kanye ne-nickel alloys. Ngaphezu kwalokho, iqukethe nezinto ezincane ezifana ne-manganese, i-titanium, i-cobalt, i-molybdenum kanye ne-cadmium, okwenza ukusebenza kwensimbi engagqwali kuzinze futhi kumelane nokugqwala kanye nokumelana nokugqwala. Insimbi engagqwali ye-Austenitic akulula ukuyiba magnetized ngenxa yokwakheka kwe-molecule yangaphakathi.
