Insimbi engagqwali engu-304 kanye nensimbi engagqwali engu-316 yenkomishi ye-thermos kungashiwo ukuthi yizinto ezimbili ezivame kakhulu zensimbi abantu abavamile abangazithinta.Uyini umehluko phakathi kwabo?Noma ake sinwebe umbuzo kancane, iyini insimbi engagqwali?Iyini i-304 noma i-316 insimbi engagqwali?Iyini insimbi?
Insimbi nensimbi
Sivame ukuzwa igama elithi "ironmaking".Okubizwa ngokuthi “ukwenza insimbi” kubhekisela ekuhlukaniseni ukungcola kwensimbi.Okuqukethwe okuphezulu kokungcola kwe-iron ore yikhabhoni - ngakho sisebenzisa izinga lekhabhoni njengezinga lokukala insimbi.
Ikhabhoni ephezulu (ngaphezu kuka-2%), ebizwa nge-iron (eyaziwa nangokuthi i-iron yengulube);okuqukethwe kwekhabhoni ephansi (2% nangaphansi), ebizwa ngensimbi (eyaziwa nangokuthi insimbi ephekiwe).Ukuphakama kokuqukethwe kwekhabhoni, kunzima kakhulu, kodwa futhi i-brittle - ngakho-ke insimbi inokuqina okungcono, kodwa ukuqina okuphansi.
Insimbi nensimbi engagqwali
Igama elivamile lensimbi "insimbi ephekiwe".Mhlawumbe ungakuqonda kangcono.Insimbi ejwayelekile emcabangweni wakho ayihlangene “nokugqwala”.Kunezinhlobo eziningi zensimbi, futhi insimbi engagqwali ingenye yazo.
Insimbi engagqwali ne-austenitic stainless steel
Esivame ukukubiza ngokuthi “insimbi engagqwali” noma “insimbi engagqwali” egameni layo eligcwele “insimbi engagqwali nensimbi engamelana ne-asidi” - eqinisweni, kulula kakhulu ukuvimbela insimbi ukuthi ingagqwali ngokungeza okunye ukungcola kwensimbi kunsimbi eyingxubevange (njengokuthi ukwengeza i-chromium).
Kodwa hhayi ukugqwala, kungasho nje ukuthi ngeke kugqwelwe wumoya, ikhono lisampofu kakhulu.Ngakho futhi siyayidinga ukuthi imelane nokugqwala kwamakhemikhali, ngakho-ke kukhona “insimbi engagqwali ene-asidi”.
Uma ufuna ukwenza insimbi engagqwali ne-asidi, udinga ukwengeza izinsimbi eziningi - ngamanye amazwi, kukhona ifomula.Kunezinhlobo ezintathu kuphela ezakhiwe ezivamile: i-martensitic stainless steel, i-ferritic stainless steel kanye ne-austenitic stainless steel.
Phakathi kwazo, insimbi engagqwali ye-austenitic inokusebenza okuphelele okuphelele futhi ayikho i-magnetism, ngakho-ke isetshenziswa kabanzi ekuphileni kwethu kwansuku zonke - i-304316 ingeyensimbi engagqwali ye-austenitic.
