Dab tsi yog 316 stainless hlau? Dab tsi yog qhov txawv ntawm daim ntawv thov ntawm 304 thiab 316 stainless hlau?
Dab tsi yog 316 stainless hlau? Dab tsi yog qhov txawv ntawm daim ntawv thov ntawm 304 thiab 316 stainless hlau?
316 stainless hlau yog siab - zoo stainless hlau paub txog nws zoo heev corrosion kuj, tshwj xeeb tshaj yog tiv thaiv chloride corrosion (xws li ntsev). Qhov no yog vim qhov sib ntxiv ntawm molybdenum, ua rau nws zoo tagnrho rau marine, tshuaj, thiab kev kho mob daim ntawv thov. 304 stainless hlau, ntawm qhov tod tes, yog tus qauv, dav dav - lub hom phiaj, thiab tus nqi- kev xaiv zoo haum rau kev siv dav dav xws li cov khoom siv hauv chav ua noj thiab cov khoom siv kho mob, qhov tsis muaj kev txhawj xeeb. Qhov sib txawv tseem ceeb ntawm ob yog tias 316 stainless hlau muaj 2-3% molybdenum, uas zoo tiv thaiv pitting thiab crevice corrosion, tshwm sim uas tuaj yeem cuam tshuam 304 stainless hlau hauv hnyav, saline, lossis acidic ib puag ncig.
Dab tsi yog qhov tsis zoo ntawm 316 stainless hlau?
Lub ntsiab tsis zoo ntawm 316 stainless hlau muaj xws li: tus nqi siab dua (vim muaj molybdenum); nyuaj ntau dua hauv kev ua / kev tsim (nrog rau kev ua haujlwm hardening); thiab muaj peev xwm rau weld corrosion yog welded tsis raug (carbide nag lossis daus), ua rau corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nplua nuj nyob rau hauv chloride ions. Txawm hais tias nws cov corrosion kuj yog superior rau 304 stainless hlau, pitting corrosion tseem tuaj yeem tshwm sim. Tsis tas li ntawd, 316 stainless hlau hnyav dua thiab xav tau cov cuab yeej tshwj xeeb thiab cov txheej txheem rau kev ua haujlwm.
316 Stainless Hlau: Taw qhia
Muaj pes tsawg leeg: Ib qho austenitic stainless hlau, zoo ib yam li 304 stainless hlau, tab sis nrog ntxiv ntawm molybdenum (2-3%) thiab nce nickel cov ntsiab lus.
Cov txiaj ntsig tseem ceeb: Txhim kho corrosion tsis kam rau chlorides (seawater, de-icing salts), muaj chemicals, thiab acids, thiab superior kev ua tau zoo nyob rau hauv siab - kub ib puag ncig.
304 Stainless hlau vs . 316 Stainless hlau
Thaum xaiv hnyav -cov khoom siv stainless hlau rooj, lub laub, thiab txee, 304 thiab 316 stainless hlau yog cov kev xaiv, tshwj xeeb tshaj yog hauv kev kho mob, kev lag luam, thiab kev lag luam.
300 series stainless hlau yog paub txog nws cov qauv austenitic, uas muab nws zoo heev txhua yam khoom thiab corrosion kuj. Ob leeg 304 thiab 316 stainless hlau muaj cov qib siab ntawm chromium thiab npib tsib xee, uas muab cov khoom zoo heev thaum tshav kub kub, hnav, thiab corrosion kuj. Lawv kuj muaj cov vuam zoo heev thiab tsim cov khoom, ua rau lawv siv dav hauv ntau qhov kev lag luam. Ob leeg 304 thiab 316 stainless hlau yog suav tias yog kev phais lossis kev kho mob-qib stainless hlau thiab yog ob hom ntawm cov hlau tsis zoo.
Txawm hais tias zoo sib xws, lawv qhov sib txawv ntawm qhov sib txawv ua rau muaj kev ua tau zoo sib txawv, ua rau lawv haum rau cov ntawv thov tshwj xeeb. Qhov sib txawv tseem ceeb tshaj plaws yog qhov sib ntxiv ntawm molybdenum; 316 stainless hlau muaj molybdenum, thaum 304 stainless hlau tsis. Cov khoom siv alloying no ua rau muaj kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv cov dej ntsev los yog siab -chloride ib puag ncig.
SAE 304 Stainless hlau
Muaj li ntawm 18% chromium thiab 8% npib tsib xee.
Feem ntau hu ua 18/8 stainless hlau.
Qee zaum muaj me me ntawm carbon, manganese, thiab silicon.
Muaj kev tiv thaiv corrosion zoo thiab tsim nyog rau ntau qhov chaw ib puag ncig, nrog rau cov kev sib cuag nrog cov tshuaj thiab cov dej noo.
SAE 316 Stainless hlau
Muaj 16-18% chromium, 10-14% nickel, thiab 2-3% molybdenum.
Qhov sib ntxiv ntawm molybdenum ho txhim kho nws cov kev tiv thaiv corrosion los ntawm chlorides thiab lwm yam corrosive hais.
Muab superior corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv chloride thiab lwm yam kev lag luam hnyav ib puag ncig.
Nws muaj lub zog tag nrho me ntsis, tshwj xeeb tshaj yog nyob rau qhov kub siab, thiab tiv taus pitting thiab crevice corrosion.
Ua kom ruaj khov thiab lub zog ntawm qhov kub thiab txias.
Qhov zoo ntawm 316 Stainless Steel piv rau 304 Stainless Hlau
Txawm hais tias ob qho tib si 304 thiab 316 stainless hlau muaj kev tiv thaiv zoo heev thiab ua haujlwm ntev, 316 stainless hlau muaj qhov zoo dua hauv nws cov tshuaj tiv thaiv chlorides thiab lwm yam tshuaj corrosive.
Vim tias muaj cov molybdenum thiab cov ntsiab lus ntau dua nickel, 316 stainless hlau pom zoo corrosion kuj ntawm qhov kub thiab txias rau ntau yam tshuaj, suav nrog sulfuric acid, bromides, iodides, thiab fatty acids. Qhov no ua rau 316 stainless hlau yog cov khoom siv zoo tshaj plaws rau cov khoom siv thiab qhov chaw hauv kev lag luam uas nquag tuaj rau hauv kev sib cuag nrog cov tshuaj corrosive thiab yuav tsum tau siv cov tshuaj ntxuav corrosive.
Ntau qhov kev lag luam, los ntawm kev pabcuam zaub mov thiab kev lag luam marine mus rau kev lag luam tshuaj thiab tshuaj, qhia txog kev siv 316 stainless hlau vim tias nws muaj zog dua nyob rau hauv ib puag ncig ntau corrosive thiab nyob rau hauv kev tu ntau zaus. Cov chav huv huv yuav tsum tau ntxuav ntau zaus thiab nruj, yog li xav tau cov khoom siv uas tuaj yeem tiv taus cov tshuaj muaj zog corrosive.
Cov khoom sib cuag thiab cov khoom siv taw taw hauv kev sib cuag nrog hauv pem teb yog qhov muaj feem cuam tshuam rau cov khoom corrosive, suav nrog tab sis tsis txwv rau cov tshuaj dawb, ammonia-raws li cov tshuaj ntxuav tes, hydrogen peroxide, thiab cov tshuaj ntxuav tu xws li Sporeklenz.
Vim tias nws muaj kev tiv thaiv ntau dua rau cov tshuaj chloride corrosion, 316 stainless hlau feem ntau hu ua marine- qib stainless hlau, vim tias nws tiv taus corrosion ntau dua los ntawm ntsev (sodium chloride) hauv dej hiav txwv dua li lwm cov hlau tsis huv.
