I-304 kunye ne-316 ziintlobo zetsimbi ezingenasici, kwaye "ukugqiba" kwazo kubhekisela kubume bomhlaba okanye ukubonakala kwentsimbi. Umahluko phakathi kwezi ntlobo zimbini ikakhulu usekubunjweni kwazo kunye neziphumo zeempawu:

Ukuqulunqwa:

304 Intsimbi engatyiwa:

Iqulethe malunga ne-18-20% ye-chromium kunye ne-8-10.5% ye-nickel.
Isenokuba nezixa ezincinci zezinye izinto ezifana nemanganese, isilicon, kunye nekhabhoni.

316 Intsimbi engatyiwa:

Iqulethe malunga ne-16-18% ye-chromium, i-10-14% ye-nickel, kunye ne-2-3% ye-molybdenum.
Ukongezwa kwe-molybdenum kwandisa ukuxhathisa kwayo ekudlekeni, ngakumbi ngokuchasene nekloridi kunye nezinye izinyibilikisi zemizi-mveliso.

Iipropati kunye nezicelo:

304 Intsimbi engatyiwa:

Ukunyangwa kokuMhlwa: Kuhle, kodwa kungabi phezulu njenge-316, ngakumbi kwiindawo ze-chloride.

Amandla: Amandla aphezulu kunye nokuqina, okulungileyo kwiinjongo eziqhelekileyo.

Usetyenziso: Isetyenziswe ngokubanzi kwizixhobo zasekhitshini, ukulungiswa kokutya, i-trim yezakhiwo, izikhongozeli zeekhemikhali, kunye nokunye ngenxa yokumelana nokubola kakuhle kunye nokulula kokucoca.

316 Intsimbi engatyiwa:

Ukunyangwa kokuMhlwa: Ingaphezulu kwe-304, ngakumbi emanzini anetyuwa okanye kwindawo yaselwandle, kunye nobukho bekloridi.

Amandla: Iyafana ne-304 kodwa ngokuchasana nokugoba okungcono.

Usetyenziso: Ilungele ukusetyenziswa kwimo engqongileyo yaselwandle, izixhobo zoxubo mayeza, izifakelo zonyango, ukusetyenzwa kweekhemikhali, kunye nayo nayiphi na imeko apho uxhathiso oluphezulu lwe-corrosion lufuneka.

Gqiba:

"Ukugqiba" kwensimbi engenasici, nokuba i-304 okanye i-316, ibhekisela ekugqityweni kwendawo, enokuthi ihluke ngokuxhomekeka kwindlela yokuvelisa. Iziqendu eziqhelekileyo ziquka:

1, Hayi. 2B: Isiphelo esigudileyo, esibuthuntu esiveliswa kukuqengqeleka okubandayo okulandelwa kukurhoxa kunye nokuhla.

2, Hayi. 4: Ukugqitywa kwebrashi, okuphunyezwa ngokuxubha ngobuchwephesha umphezulu ukwenza ipatheni yemigca ecolekileyo ehambelana nolwalathiso lwebrashi.

3, Hayi. 8: Isiphelo esifana nesipili esiveliswe ngokugudiswa ngokulandelelana kweziabrasives ezicolekileyo kunye nebuffing.

Zombini i-304 kunye ne-316 i-stainless steels ingaba nokugqiba okufanayo, kodwa ukhetho phakathi kwe-304 kunye ne-316 luya kuxhomekeka kwiimeko ezithile zokusingqongileyo kunye neempawu ezifunekayo kwisicelo.

Ngaba i-316 okanye i-304 ibiza ngaphezulu?

Ngokuqhelekileyo, i-316 insimbi engenasici ibiza kakhulu kune-304 insimbi engenasici. Isizathu esiphambili salo mahluko wexabiso kukubunjwa kwe-316 yensimbi engenasici, equka ipesenti ephezulu ye-nickel kunye nokongezwa kwe-molybdenum. Ezi zinto ziphakamisa ukuxhathisa kwe-corrosion ye-316 yensimbi engenasici, ngakumbi kwi-chloride kunye neendawo zaselwandle, kodwa zikwafaka isandla kwiindleko eziphezulu zempahla.

Nasi isishwankathelo sezinto ezinegalelo kumahluko weendleko:

Ukuqulunqwa kwezinto:

304 Intsimbi engatyiwa: Iqulethe malunga ne-18-20% ye-chromium kunye ne-8-10.5% ye-nickel.
316 Intsimbi engatyiwa: Iqulethe malunga ne-16-18% ye-chromium, i-10-14% ye-nickel, kunye ne-2-3% ye-molybdenum.

Ukunyangwa kokuMhlwa:

316 Intsimbi engatyiwa: Inikeza ukuxhathisa okungaphezulu kokuhlwa, ngakumbi ngokuchasene neekloridi nakwiimekobume zaselwandle, ngenxa yobukho bemolybdenum.
304 Intsimbi engatyiwa: Inokumelana ne-corrosion elungileyo kodwa ayisebenzi kangako kwindawo enomhlwa kakhulu xa kuthelekiswa ne-316.

Iindleko zeMveliso:

Izixa eziphezulu ze-nickel kunye nokongezwa kwe-molybdenum kwi-316 yensimbi engenasici kubangela ukunyuka kweendleko zezinto eziluhlaza.
Iindleko zokusetyenzwa kunye nemveliso nazo zinokuba phezulu kwi-316 yensimbi engenasici ngenxa yokwakheka kwayo kwe-alloy eyinkimbinkimbi.

Ngoko ke, kwizicelo apho ukuxhatshazwa kwe-corrosion ephezulu ye-316 yensimbi engenasici ayifuni, i-304 insimbi engenasici idla ngokukhethwa njengenye indlela engabizi.
