I-304 vs 316 iNtsimbi engagqwali: Ukubunjwa, uKutya, kunye noKhetho

info-813-502

Nguwuphi Umahluko phakathi kwe-304 kunye ne-316 yentsimbi engatyiwayo?

I-304 kunye ne-316 insimbi engenasici zombini i-austenitic stainless grade, kodwa ayitshintshi xa indawo yenkonzo iba nzima ngakumbi. Owona mahluko ubalulekileyo wobugcisa kukubunjwa: umgangatho we-304 yichromium -nickel yensimbi engenasici, ngelixa i-316 yongeza malunga ne-2-3% ye-molybdenum kwaye ihlala iphethe uluhlu oluphezulu lwe-nickel. Oko kudityaniswa kwemolybdenum sesona sizathu i316 ibonelela ngokuxhathisa ngcono kwimingxuma kunye nokuhlwa kwemingxuma kwikloridi{10}}indawo ezithweleyo ezifana nomoya waselunxwemeni, ungcoliseko lwetyuwa, ukuhlanjwa kweekhemikhali, kunye nezinye iinkonzo zenkqubo. Ngokuchaseneyo, i-304 lelona bakala liqhelekileyo{13}}lenjongo yomgangatho wesixhobo sangaphakathi, umsebenzi weatmosfera ophakathi, kunye neendawo ezenziweyo apho utyhileko lwekloridi luthintelweyo.

Umahluko phakathi kwe-304 kunye ne-316 yensimbi engenasici ngoko ayingombuzo wamandla okanye ukubonakala. Kwimeko ye-annealed esemgangathweni, amanqanaba abo omatshini asisiseko asondele kakhulu, kwaye omabini asetyenziswa ngokubanzi kwiphepha, ipleyiti, ityhubhu, umbhobho, izifakelo, iitanki kunye nezixhobo ezenziweyo. Olona lwahlulo luyi-corrosion margin. Ukuba inkonzo yomile, icocekile, kwaye ayikho{5}}nobundlobongela, 304 ihlala yanele. Ukuba umphezulu uza kubona iikloridi,{8}}utyhileko olukufutshane, okanye ikhemistri yokucoca engqongqo, i-316 ihlala ibonelela ngesiseko semathiriyeli ethembekileyo. Lowo ngumahluko obonakalayo phakathi kwe-304 kunye ne-316 yensimbi engenasici kusetyenziso lobunjineli.

Ulwahlulo lweMathiriyeli ye-304 kunye ne-316 yeNsimbi eNgatyiwayo

304 kunye 316 ngamalungu e300-series austenitic steel stainlessiqela. Uthelekiso ke ngoko alukho phakathi kweeklasi ezimbini zemathiriyeli ezahluke ngokupheleleyo, kodwa phakathi kwechromium ezimbini ezisondeleleneyo{1}}zezintsimbi zenickel ezingenastainless ezinendlela efanayo yokwenza kunye nokuziphatha kwewelding, kodwa ukusebenza komhlwa okwahlukileyo xa iikloridi kunye neemekobume eziqatha zingena emfanekisweni.

Olu lwahlulo lukwafanelekile kuzo zonke iifom zemveliso yokugaya eqhelekileyo, kubandakanywaikhoyili yentsimbi engenasici, ishiti, ipleyiti, umbhobho, kunye netyhubhu. Kwizicelo zekhoyili, i-304 kunye ne-316 zinokubonelelwa ngazo zombini ukwenza, ukwenza, kunye nokusetyenzwa phantsi komsinga, kodwa akufuneki ziphathwe njengento etshintshayo xa indawo yenkonzo ingenisa ikloridi{3}}ithwele ukufuma, idiphozithi yetyuwa, okanye ukuvezwa kweekhemikhali ezinobundlobongela.

Ukususela kumbono wobunjineli, yingakho i-304 kunye ne-316 insimbi engenasici ihlala ifaniswa kwiiprojekthi ezifanayo. Zombini zinokwanelisa uninzi lweendlela ezifanayo zokwenziwa, kodwa aziphenduli ngokulinganayo kwindawo enye yenkonzo.

Umahluko Wokuqulunqa phakathi kwe-304 kunye ne-316 yeNsimbi eNgatyiwayo

I-304 kunye ne-316 Stainless Steel umsantsa weekhemikhali uqondile. Umgangatho wama-304 wakhiwe malunga nechromium kunye nenickel. Umgangatho we-316 usebenzisa isiseko esifanayo, kodwa wongeza i-molybdenum kwaye ngokuqhelekileyo ithwala uluhlu oluphezulu lwe-nickel. Eso sizathu siphambili i-316 idla ngokukhethwa xa ukuxhathisa kwekloride kubaluleke kakhulu.

Le theyibhile icacisa ukuba kutheni I-304 kunye ne-316 umahluko wensimbi engenasiciayiqhelekanga ukuchazwa njengophuculo lwamandla kuqala. Luphuculo lwekhemistri -eqhutywa ngumhlwa.

Ukumelana nokubola ngowona mgca wokuhlula

Kufakelo oluninzi lokwenyani, umbuzo awukho ukuba zombini izixhobo azinastainless, kodwa ukuba imo engqongileyo iqulethe ikloridi ezaneleyo ukwenza i-304 ithembeke kancinci ekuhambeni kwexesha. I-Chlorides yindawo apho uthelekiso lwe-304 kunye ne-316 yensimbi engenasici luba lukhulu ngakumbi. Isitshizi setyuwa, umoya wolwandle, iityuwa ze-deicing, iklorine{5}}ezithwala izicoci, kunye nezinye iikhemikhali zenkqubo zinokutyhala i-304 ekungcoleni, emingxunyeni, okanye kumhlwa phambi kwe-316.

I-316 ayikhuseli kumhlwa ngenxa yokuba iqulethe i-molybdenum. Isenemida. Kodwa kwi chloride-inkonzo yokuthwala, ibonelela ngokubanzi ngomda wokusebenza obanzi kune 304.

FAQ

01.Ngaba i-316 ihlala ingcono kune-304 yensimbi engenasici yokusetyenziswa kwangaphandle?

Hayi. Kwinkonzo yangaphandle epholileyo kude netyuwa,304ihlala yanele.316iba lolona khetho lungcono xa umphezulu utyhilekileiikloridi, umoya wonxweme, iityuwa ze-deicing, okanye iidiphozithi eziqhubekayo.

02.Kweyiphi inqanaba lekloridi kufuneka i-304 iphuculwe kwi-316 yensimbi engenasici?

Njengesikhokelo esipapashiweyo seingathathi hlangothi,-inkonzo yobushushu obuqhelekileyo, 304/304Lihlala ilinganiselwe malunga200 ppm iikloridi, ngelixa316/316Linokwandisa ukuya malunga1000 ppm. Ukuqhekeka, ubushushu, iidiphozithi, kunye nokungahambi kakuhle kunokunciphisa loo mida.

03.Kwizinto ezenziwe nge-welded, ngaba ndifanele ndithelekise i-304 vs 316 okanye i-304L vs 316L?

Kwizixhobo ezidityanisiweyo, uthelekiso oluluncedo ngakumbi luhlala lukhona304L vs 316L, ngokuba iamabanga{{0}ekhabhoni L asezantsizikhethwa apho i-welding kunye-ne-weld corrosion control matter. Ukhetho phakathi kwe-304L kunye ne-316L kufuneka lulandele indawo yenkonzo yangempela.

04. Ngaba i-316 insimbi engenasici ifanelekile kumanzi olwandle okanye inkonzo yekloridi eshushu?

Ayizenzekeli.316ingcono kune304, kodwa kunjalohayi ibakala lamanzi olwandle jikelele. I-ASSDA iphawula ukuba amanzi olwandle ajikelezile20,000 ppm iikloridi, kunye neemeko zekloridi ezishushu zinokuphinda zicuthe ifestile yokusebenza ekhuselekileyo.
