Impendulo kukuba umgangatho we316 intsimbi engatyiwayoingcono kune304 intsimbi engenasici, ngenxa yokuba i-316 insimbi engenasici idibaniswe ne-metal molybdenum ngesiseko se-304, le nto inokudibanisa ngakumbi i-molecular structure yensimbi engenasici, eyenza ibe yinto enqabileyo kunye ne-anti-oxidation, kwaye ngexesha elifanayo, ukuxhathisa kwe-corrosion kwanda kakhulu. Makhe sijonge 304 steel stainless kunye 316 steel stainless okulungileyo. Iindidi ezisetyenziswa kakhulu zentsimbi engenasici yi-304 kunye ne-316. Inkqubo yolawulo lokuhlelwa esetyenziselwa ukuhlelela ezi ntlobo zimbini zentsimbi ivela ngokuyintloko kwinkqubo yolwazi yokubala iqalwe yi-American Iron and Steel Association of China (AISI), enye yeenzame zomanyano zakudala ukuza kuthi ga ngoku ubuyela emva 1855. Ezi zigaba zibonisa ukubunjwa kwazo, kwaye uninzi lwe-2000 ye-steel 3000 - kwaye ithathwa njenge-steel 3000. Inkqubo ye-austenitizing ibandakanya ukufudumeza isinyithi, i-ferroalloy, okanye intsimbi ukuya kwindawo apho isakhiwo sayo sekristale sitshintsha ukusuka kwi-ferrite ukuya kwi-austenite. Nangona kunzima ukuhlukanisa ezi zimbini ngeso lenyama, iimpawu zemveliso ezizodwa phakathi kwe-304 kunye ne-316 yeenkampani zensimbi ezingenasici zingenza ukuba ziphakame kwezinye izicelo zobugcisa.
Ukusukela ekuphuhlisweni kwemveliso yaseTshayina ngenkulungwane yama-20, iinkampani zensimbi ezingenasici ziye zaba zizinto ezibalulekileyo ezinempembelelo kwiiprojekthi ezininzi eTshayina ngenxa yokuqina kwazo, ukusebenza okuphezulu koomatshini, ukuwelda kunye nokuguquguquka. Iqulethe iipesenti ezininzi ezahlukeneyo zezinto ezinoxanduva lwamanqanaba ahlukeneyo aziwayo ngoku. Ibakala ngalinye lineempawu zalo ezikhethekileyo, kwaye ukuthelekiswa phakathi kwamabakala amabini, njengokuba ixesha lingenasiphelo njengoko kuveliswa, yi-304 kunye ne-316 yensimbi engenasici.
Yiyiphi engcono, i-304 okanye i-316 yensimbi engenasici
Xa ujonga iintlobo ezimbini zetsimbi, zifana ngokubonakala kunye nokwakheka kweekhemikhali. Zombini zibonelela ngokhuseleko olugqwesileyo kumhlwa kunye nomhlwa, ngelixa zikwabonelela ngokuqina okongeziweyo. Xa uthelekisa i-304 kunye ne-316 yensimbi engenasici, ixabiso eliphezulu kakhulu lelo mva linokuthi libhekiselele ekuxhathiseni ukugqwala okungcono. Ngenxa yalo mahluko wexabiso kunye nokusingqongileyo okulinganiselweyo kukulungele i-316 yentsimbi, i-304 yentsimbi yeyona isetyenziswa kakhulu i-austenitic stainless steel.
IBanga le-316 insimbi engenasici ixabisa ngakumbi ngenxa yokumelana nokugqwala okungcono. Ukusetyenziswa apho i-alloys ibonakaliswe kwizisombululo zeklorini kunye nekloridi (kubandakanywa namanzi olwandle aseTshayina), kucetyiswa ngokukodwa ukuba inkqubo isetyenziswe ngale ngxube enamabanga aphezulu aphezulu. Ingasetyenziselwa ukwandisa ubomi bothungelwano lwenkonzo yamacandelo okanye izixhobo ezithi ngokuthe ngcembe zibe sesichengeni kwiimeko ezirhabaxa nezonakalisayo zokusingqongileyo, ngakumbi kwiimeko ezibandakanya ukuvezwa okuyingxaki kwityuwa. Nangona kunjalo, inqanaba lama-304 liluncedo kakhulu kwizicelo ezininzi. Isishwankathelo, xa ujonga i-304 kunye ne-316 i-stainless steels, kwizicelo ezifuna i-corrosion egqwesileyo okanye ukuxhathisa kwamanzi, sebenzisa i-316 stainless steels. Kwezinye izicelo, i-304 insimbi engenasici nayo yenziwe ngobunjineli. Kuzo zonke, i-304 kunye ne-316 ziikhowudi zensimbi engenasici, ngokwenene, akukho mahluko phakathi kwazo zinsimbi ezingenasici, zihlulwe zivela kwiindidi ezahlukeneyo. Ukubeka nje, umgangatho we-316 yensimbi engenasici inkulu kune-304 yensimbi engenasici, i-316 insimbi engenasici ngesiseko se-304 kwi-molybdenum yesinyithi, le nto inokudibanisa ngakumbi i-molecular structure yensimbi engenasici, iyenze ibe nokuxhathisa ukunxiba kunye ne-oxidation, kwangaxeshanye, ukuxhathisa ukubola kukwande kakhulu.
