I-304 kunye ne-316 insimbi engenasici zizinto ezimbini eziqhelekileyo zensimbi ezingenasici. Umahluko phakathi kwabo ikakhulu ulele ekubunjweni kweekhemikhali kunye neendawo zokusebenzisa. I-316 insimbi engenasici iqulethe i-chromium ephezulu kunye nomxholo we-nickel kune-304 yensimbi engenasici, eyenza i-316 insimbi engenasici ibe ne-corrosion resistance resistance, ngakumbi ngokuchasene ne-chloride media. Ngoko ke, i-316 insimbi engenasici ifanelekile ngakumbi ukuba isetyenziswe kwiindawo ezineemfuno eziphezulu zokumelana ne-corrosion, ezifana neendawo zamanzi olwandle okanye amashishini ekhemikhali. I-304 yensimbi engenasici idla ngokusetyenziswa kwizicelo zenjongo jikelele ezifana nezixhobo zasekhitshini, izinto zokwakha, njl.
Xa kuziwa kwi-304 kwaye316 intsimbi engatyiwayo, sinokufunda ngakumbi malunga neempawu zabo zokusebenza. Ukongeza kwimichiza yabo, iintsimbi ezimbini ezingenasici nazo ziyahluka kwiipropathi zabo zomatshini kunye nokuqhubekeka. I-316 intsimbi engatyiwayo ngokubanzi inamandla aphezulu okuqina kunye namandla acinezelayo, kodwa inokuba neplastikhi esezantsi ngokwentelekiso. Ukongezelela, iipropati zokunyanga ukushisa kwe-316 insimbi engenasici ayinakuguquguquka njenge-304 yensimbi engenasici, ngoko ke ingqwalasela engakumbi kunye nezakhono zingafuneka ekuqhubeni nasekuqulunqeni. Ukongezelela, kukho ezinye iintlobo zezinto zensimbi ezingenasici, ezifana ne-304L kunye ne-316L, ezinomxholo ophantsi wekhabhoni kwaye zifaneleke ngakumbi ukuphepha ukuveliswa kwe-precipitates ngexesha le-welding. Ngoko ke, xa ukhetha izinto zensimbi ezingenasici, ngaphezu kokuqwalasela ukuxhathisa kwayo, kuyafuneka ukuba kuqwalaselwe iimpawu zayo zomatshini, ukucubungula ukusebenza kunye neemfuno zeendawo ezithile zesicelo ukwenzela ukuba ukhethe izinto ezifanelekileyo kakhulu.
Xa sisenza nzulu ngakumbi ukuqonda kwethu kwe-304 kunye ne-316 yensimbi engenasici, sinokuqwalasela iimpawu zabo zokubola kwiindawo ezithile. Ngenxa yesiqulatho se-molybdenum, i-316 yentsimbi engatyiwayo inokumelana nomhlwa ngokubanzi kune-304 yentsimbi engatyiwayo, ngakumbi kwindawo ene-ion ye-chloride, efana namanzi olwandle okanye amanzi etyuwa. Oku kwenza316 intsimbi engatyiwayoolona khetho lwemathiriyeli lufaneleke ngakumbi ukuba lusetyenziswe kwindawo ezingqongileyo zaselwandle okanye kumashishini amachiza. Ukongezelela, ukungafani kokusebenza kwezi zimbini zensimbi ezingenasici kwiindawo eziphezulu zokushisa zingaphononongwa ngakumbi, kunye nokusetyenziswa kwazo kumashishini athile afana nokulungiswa kokutya kunye nezixhobo zonyango. Ngokuqonda okunzulu, sinokukhetha ngokuchanekileyo izinto ezifanelekileyo zensimbi ezingenasici kwiimeko ezahlukeneyo zesicelo ukuqinisekisa ukuba zisebenza ngokufanelekileyo kwiindawo ezithile kunye neemeko.
Ukukhetha i-304 okanye i-316 yensimbi engenasici ixhomekeke kwiimfuno ezithile zesicelo. Ngokuqhelekileyo, i-304 insimbi engenasici inokumelana nokugqwala okulungileyo kwaye ifanelekile kwiindawo eziqhelekileyo zangaphakathi nangaphandle, ngelixa i-316 insimbi engenasici inokumelana ne-corrosion ephezulu kuba iqulethe i-molybdenum kwaye ifanelekile ukusetyenziswa kwiindawo ezinobungozi kakhulu, ezifana namanzi olwandle. Ushishino lwendalo okanye lwekhemikhali. Ngoko ke, iyona ndlela ilungileyo yokukhetha i-304 okanye i-316 yensimbi engenasici ngokwemiqathango ethile yokusetyenziswa kunye neemfuno.
