I-304 kunye ne-316 zombini iikhowudi zensimbi engenasici.Enyanisweni, abahlukanga.Zombini ziyintsimbi engatyiwayo, kodwa zezeentlobo ezahlukeneyo xa zahlulwe.Umgangatho we-316 yensimbi engenasici iphezulu kuneye-304 yensimbi engenasici.Ngokusekelwe kwi-304,316 intsimbi engatyiwayoidibanisa i-metal molybdenum, enokuthi idibanise ngakumbi i-molecular structure yensimbi engenasici.Yenze ikwazi ukumelana nokunxitywa kunye ne-anti-oxidation, kwaye kwangaxeshanye, ukuchasana kokubola kukwandisiwe kakhulu.
Ukuthelekisa ukusebenza kwe304L kunyeI-316L ibrashi ipleyiti yeNsimbi eNgatyiwayo
I-corrosion resistance of steel stainless steel ixabiseke kakhulu kunokumelana nebala.Njenge-alloy, ukubunjwa kokuqala kwensimbi engenasici yintsimbi, kodwa ngenxa yokongezwa kwezinye izinto, kunokufikelela kwiipropati ezininzi ezinqwenelekayo zesicelo.I-Chromium yinto emiselweyo kwinsimbi engenasici, ubuncinane i-10.5% yokwakheka.Ezinye izinto ezidibanisa i-nickel, i-titanium, i-copper, i-nitrogen kunye ne-selenium.
Umahluko phakathi kwe-304L kunye ne-316L ye-Stainless Steel Plate kubukho be-chromium, i-316L ibrashi yensimbi engenasici inokumelana nokugqwala okungcono, ngakumbi kwindawo ephakathi kunye netyuwa ephezulu.Ukusetyenziswa kweemveliso zentsimbi yangaphandle, insimbi engenasici yinto efanelekileyo yokumelana ne-corrosion kwi-exposure yangaphandle yexesha elide.
ukumelana nomhlwa kwendalo
Imixholo eyahlukeneyo yechromium kunye nezinye izinto zinokubonisa amanqanaba ahlukeneyo okumelana nomhlwa.Awona manqanaba mabini axhaphakileyo entsimbi engatyiwayo ngama-304 kunye nama-316. Umhlwa yinto yendalo, kanye njengokuba intsimbi isabela ngokwendalo kunye nendawo eyingqongileyo.Enyanisweni, izinto ezimbalwa kakhulu ezinokuthi zenzeke kwifomu ecocekileyo - igolide, isilivere, ubhedu, kunye neplatinam yimizekelo embalwa kakhulu.
I-Chromium oxide yenza ifilimu ekhuselayo eyakhiwe ngaphakathi
Ukugqwala yinkqubo apho iimolekyuli zentsimbi zidibanisa neoksijini kwiimolekyuli zamanzi, kwaye umphumo uba yibala elibomvu eliye libi nakakhulu-ukugqwesa izinto ezininzi.Kwezi, intsimbi kunye nentsimbi yekhabhoni zichaphazeleka ngakumbi kulo mhlwa.
Intsimbi engatyiwayo inamandla endalo okonakalisa umphezulu, kwenzeka njani oku?I-Chromium kuzo zonke iintsimbi ezingenastainless isabela ngokukhawuleza kwioksijini, njengentsimbi.Umahluko kukuba kuphela umaleko obhityileyo wechromium oza kuxutywa nge-oxidized (ngokuqhelekileyo nje i-molecule encinci kubukhulu).Okumangalisayo kukuba, lo maleko ubhityileyo wokhuseleko lomelele kakhulu.
I-304L ibrashi yensimbi engenasici inenkangeleko entle kunye neendleko zokugcina eziphantsi.I-304L ibrashi yentsimbi engatyiwayo ayithandeki ukuba nomhlwa, ngoko isoloko isetyenziswa kwi-cookware kunye nezicelo zokutya.Kodwa ichaphazeleka kwikloridi (ngokuqhelekileyo kwiindawo ezinetyuwa eninzi).I-Chloride idala uhlobo lwendawo enomhlwa ebizwa ngokuba yi "corrosion spot" ephumela kwisakhiwo sangaphakathi.
I-304 insimbi engenasici yeyona isetyenziswa kakhulu emhlabeni.Iqulethe i-16% -24% yechromium kunye ne-35% ye-nickel - kunye namanqanaba aphantsi ekhabhoni kunye ne-manganese.Uhlobo oluqhelekileyo lwe-304 yensimbi engenasici yi-18-8, okanye i-18/8 yensimbi engenasici, ebhekisela kwi-18% ye-chromium kunye ne-8% ye-nickel.
I-316 insimbi engenasici ikwayintsimbi esetyenziswa ngokubanzi kakhulu.Iimpawu zayo ezibonakalayo kunye nezixhobo zifana ne-304 yensimbi engenasici.Umahluko kukuba i-316 insimbi engenasici iqulethe i-2-3% molybdenum, eyandisa amandla kunye nokuxhatshazwa kwe-corrosion.Ngokuqhelekileyo i-300 series steels stainless ingaqulatha ukuya kwi-7% ye-aluminiyam.
I-304L kunye ne-316Liintsimbi ezixutyiweyo(njengezinye ii-300 series steels stainless) sebenzisa i-nickel ukugcina i-aesthetics yabo yobushushu obuphantsi.
