Insimbi engagqwali iwuhlobo lwengxube yensimbi equkethe insimbi njengenye yezingxenye zayo eziyinhloko, kanye ne-chromium, i-nickel, nezinye izakhi.Ukuthi insimbi engagqwali iyizibuthe noma cha kuncike ekwakhekeni kwayo okuthile kanye nendlela ecutshungulwe ngayo.Akuzona zonke izinhlobo zezinsimbi ezingenasici ezinozibuthe.Kukhona izinsimbi ezingagqwali kazibuthe nezingezona uzibuthe, kuye ngokwakhiwa.
Yiniinsimbi engagqwali?
Insimbi engagqwali iyingxubevange yensimbi engagqwali, i-chromium, kanye nezinye izakhi ezifana ne-nickel, i-molybdenum, noma i-manganese.Ibizwa ngokuthi "i-stainless" ngoba imelana nokubola nokugqwala, okuyenza ibe ukukhetha okudumile ezinhlotsheni eziningi zezinhlelo zokusebenza lapho ukuqina nokumelana nezinto zemvelo kubalulekile.Insimbi engagqwali imelana nokubola nokugqwala ngenxa yezinto eziqukethwe ngaphakathi: insimbi, i-chromium, i-silicon, i-carbon, i-nitrogen, ne-manganese.Kufanele yenziwe okungenani nge-chromium engu-10.5% futhi okungenani ibe ngu-1.2% wekhabhoni ezoqashelwa njengensimbi engagqwali.
Izinhlobo zensimbi engagqwali
Insimbi engagqwali iza ngezinhlobo noma amamaki ahlukahlukene, ngalinye linokwakheka kwalo nezici ezihlukile.Lawa mabanga ahlukaniswe imindeni emihlanu emikhulu:
1.I-Austenitic Stainless Steel (300 Series):Insimbi engagqwali ye-Austenitic iwuhlobo olujwayeleke kakhulu futhi yaziwa ngezindawo zayo ezingezona uzibuthe, ukumelana nokugqwala okuhle kakhulu, kanye nokwakheka okuhle.
2.I-Ferritic Stainless Steel (400 Series):Insimbi engagqwali ye-Ferritic inozibuthe futhi inokumelana nokugqwala okuhle, noma ikwazi ukumelana nokugqwala njengensimbi engagqwali ye-austenitic. Amabanga avamile ahlanganisa u-430 no-446.
3.I-Martensitic Stainless Steel (400 Series):Insimbi engagqwali ye-Martensitic nayo inozibuthe futhi inamandla amahle nobulukhuni.Isetshenziswa ezinhlelweni lapho ukumelana nokugqokwa nobulukhuni kubalulekile.Amabanga ajwayelekile afaka u-410 no-420.
4.I-Duplex Stainless Steel:I-Duplex insimbi engagqwali ihlanganisa izakhiwo zazo zombili izinsimbi ezingenasici ze-austenitic ne-ferritic.Inikeza ukumelana nokugqwala okuhle kakhulu namandla aphezulu.Amabanga ajwayelekile afaka u-2205 no-2507.
5.Insimbi Engagqwali Yokuqina Kwemvula:Insimbi engagqwali eyenza umzulu ibe lukhuni ingaphathwa ngokushisa ukuze izuze amandla aphezulu nobulukhuni.Amabanga ajwayelekile afaka phakathi u-17-4 PH no-15-5 PH.
Yini eyenza insimbi engagqwali ikazibuthe?
Insimbi engagqwali ingaba nguzibuthe noma engeyona i-magnetic, kuye ngokwakheka kwayo okukhethekile kanye ne-microstructure.Izici zensimbi engagqwali kazibuthe zensimbi engagqwali zincike esakhiweni sayo sekristalu, ukuba khona kwezakhi ze-alloying, kanye nomlando wayo wokucubungula.Insimbi engagqwali ye-Austenitic ngokuvamile ayiyona i-magnetic, kuyilapho izinsimbi ezingenasici ze-ferritic ne-martensitic zivame ukuba kazibuthe.Kodwa-ke, kubalulekile ukuqaphela ukuthi kungase kube khona ukuhluka phakathi kwesigaba ngasinye ngokusekelwe ekwakhiweni kwe-alloy ethize kanye nezinqubo zokukhiqiza.
