Vim li cas 316 kim dua 304?
Stainless hlau yog ib qho ntawm cov khoom siv dav hauv ntiaj teb. Nws yog siv rau ntau yam kev siv, los ntawm cov khoom siv hauv chav ua noj mus rau skyscrapers. Ob hom stainless hlau feem ntau yog 316 thiab 304. Thaum lawv yog ob qho tib si stainless hlau, muaj qee qhov sib txawv ntawm lawv uas ua rau 316 kim dua 304. Hauv kab lus no, peb yuav tshawb xyuas qhov sib txawv ntawm 316 thiab 304, thiab vim li cas 316 kim dua.
Stainless hlau yog dab tsi?
Stainless hlau yog ib hom hlau uas muaj tsawg kawg yog 10.5% chromium, uas ua rau nws tiv taus corrosion. Cov chromium nyob rau hauv cov hlau reacts nrog oxygen los tsim ib txheej tiv thaiv ntawm chromium oxide nyob rau saum npoo ntawm cov hlau. Cov txheej ntawm chromium oxide no tiv thaiv cov hlau los ntawm xeb, txawm tias raug huab cua thiab ya raws.
Stainless hlau kuj tseem alloyed nrog lwm yam hlau, xws li npib tsib xee thiab molybdenum, los txhim kho nws cov khoom. Qhov sib ntxiv ntawm cov hlau no ua rau cov hlau muaj zog dua, ruaj khov dua, thiab tiv taus corrosion ntau dua.
Stainless hlau yog siv nyob rau hauv ntau yam kev siv, los ntawm cov khoom siv hauv chav ua noj thiab cutlery mus rau cov khoom siv kho mob thiab cov khoom siv. Nws kuj yog siv rau hauv architecture thiab kev tsim kho, qhov twg nws yog siv los ua txhua yam los ntawm lub tsev facades mus rau cov qauv kev txhawb nqa.
Dab tsi yog 304 stainless hlau?
304 stainless hlau yog ib hom austenitic stainless hlau. Nws muaj 18% chromium thiab 8% npib tsib xee, ua rau nws yog ib qho ntawm feem ntau siv qib ntawm stainless hlau. Nws tseem hu ua 18/8 stainless hlau, vim nws 18% chromium thiab 8% nickel cov ntsiab lus.
304 stainless hlau yog qhov muaj zog tiv taus corrosion, thiab yog tsim rau siv nyob rau hauv ntau yam kev siv, nrog rau cov tais diav, cutlery, thiab dab dej. Nws kuj yog siv rau hauv kev lag luam khoom noj thiab dej haus, qhov uas nws nyiam rau nws cov corrosion kuj thiab yooj yim ntawm kev tu.
Dab tsi yog 316 stainless hlau?
316 stainless hlau yog ib hom austenitic stainless hlau. Nws muaj 16-18% chromium, 10-14% nickel, thiab 2% molybdenum. Lub molybdenum hauv 316 stainless hlau muab kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig chloride. Qhov no ua rau 316 stainless hlau zoo tagnrho rau siv nyob rau hauv marine ib puag ncig, nrog rau hauv kev lag luam tshuaj thiab tshuaj.
316 stainless hlau tseem hu ua marine qib stainless hlau, vim nws muaj kev tiv thaiv corrosion nyob rau hauv dej ntsev ib puag ncig. Nws kuj tseem siv rau hauv kev tsim cov khoom siv kho mob, qhov twg nws cov biocompatibility thiab corrosion kuj ua rau nws cov khoom zoo tagnrho.
Vim li cas 316 stainless hlau kim dua 304?
Muaj ntau qhov laj thawj vim li cas 316 stainless hlau kim dua 304 stainless hlau.
Ua ntej, 316 stainless hlau muaj molybdenum, uas yog ib qho tsis tshua muaj hlau uas kim tshaj npib tsib xee thiab chromium, cov hlau siv los ua 304 stainless hlau. Qhov sib ntxiv ntawm molybdenum rau 316 stainless hlau nce nws cov corrosion kuj, ua rau nws haum rau siv nyob rau hauv hnyav ib puag ncig. Txawm li cas los xij, qhov no los ntawm tus nqi, vim molybdenum yog hlau kim dua nickel thiab chromium.
Thib ob, 316 stainless hlau feem ntau yog siv rau hauv cov ntawv thov uas nws tseem ceeb heev uas cov khoom tsis corrode. Piv txwv li, nyob rau hauv marine ib puag ncig, corrosion ntawm hlau tuaj yeem ua rau muaj teeb meem loj, xws li kev puas tsuaj ntawm cov qauv thiab kev nyab xeeb. Vim li no, tus nqi ntawm 316 stainless hlau feem ntau yog kev ncaj ncees los ntawm qhov tseeb tias nws muaj kev ntseeg siab thiab ruaj khov dua li lwm hom stainless hlau.
Thaum kawg, qhov kev thov rau 316 stainless hlau yog siab dua li ntawm 304 stainless hlau, tshwj xeeb tshaj yog nyob rau hauv kev lag luam xws li marine engineering thiab zus tau tej cov kev kho mob cog. Qhov kev thov siab dua no thawb tus nqi ntawm 316 stainless hlau.
Xaus
Hauv kev xaus, 316 stainless hlau yog kim dua 304 stainless hlau vim nws muaj molybdenum, uas yog ib qho tsis tshua muaj hlau uas kim dua nickel thiab chromium. Tsis tas li ntawd, 316 stainless hlau feem ntau yog siv rau hauv cov ntawv thov uas nws tseem ceeb heev uas cov khoom tsis corrode, uas ua rau cov nqi siab dua. Thaum kawg, qhov kev thov rau 316 stainless hlau yog siab dua li ntawm 304 stainless hlau, tshwj xeeb tshaj yog nyob rau hauv kev lag luam xws li marine engineering thiab zus tau tej cov kev kho mob cog.
