Dab tsi yog qhov txawv ntawm 304, 316 thiab 201 stainless hlau?
Hlau yog ib qho hlau thiab tag nrho cov kab hlau no muaj cov khoom sib txawv - feem pua ntawm ntau yam khoom uas muab nws qee yam zoo. Stainless hlau 304 muaj 18% chromium thiab 8% npib tsib xee. Qhov no ua rau nws tiv taus oxidation - xeb - thiab ruaj khov heev. Cov hlau no tsis muaj kev txwv rau qhov twg nws tuaj yeem siv tau.
316 steel muaj tsawg dua chromium thiab ntau nickel thiab suav nrog cov khoom hu ua molybdenum. Cov alloy no yog ib qho ntawm feem ntau corrosion-resistant thiab kuj yog cov feem ntau resistant rau chlorine thiab ntsev. Qhov no yog vim li cas nws feem ntau siv nyob rau hauv offshore, marine thiab washdown daim ntaub ntawv. Nws tseem yog qhov xav tau ntau dua hauv kev lag luam tshuaj, vim tias molybdenum pab kom tsis txhob muaj kab mob ntawm cov hlau.
Thaum kawg, 201 stainless hlau yog tus cwj pwm los ntawm cov ntsiab lus tsis tshua muaj npib tsib xee, uas yog vim li cas nws pheej yig heev. Txawm li cas los xij, nws tsis tiv taus corrosion, yog li cov vaj tsev ntawm cov hlau no tsis haum rau kev siv sab nraum zoov. Tag nrho cov no muaj nyob rau hauv tsev neeg austenitic, uas yog cov hlau tsis muaj hlau nplaum uas tuaj yeem welded ntawm txhua qhov kub. Cov tsev neeg no tuaj yeem muab faib ua 2 series: 300 thiab 200. Koj yuav tsis tuaj yeem qhia qhov txawv ntawm tag nrho cov hlau no tsuas yog saib lawv.
Yog li ntawd, koj yuav tsum tau kuaj xyuas cov chaw tsim khoom daim ntawv tshaj tawm kom paub meej tias siv hom stainless hlau raug siv. Txhawm rau xaiv hom lossis qib ntawm stainless hlau, xav txog qhov zoo koj xav tau thiab mus los ntawm qhov ntawd. Koj tseem tuaj yeem tiv tauj peb rau kev tawm tswv yim!
Dab tsi yog qhov txawv ntawm stainless hlau, hlau, thiab galvanized steel enclosures?
Ua ntej, cov hlau zoo tib yam yog sib xyaw ntawm cov hlau thiab cov pa roj carbon, uas yog vim li cas nws tseem hu ua carbon steel thiab me me hlau. Hlau yog muaj zog, tab sis nws nyhav rau xeb thiab stains. Peb tuaj yeem ua cov vaj tsev steel, tab sis lawv tsis tiv taus corrosion li stainless hlau vaj tse.
Stainless hlau yog hloov kho los ntawm kev ntxiv chromium, nickel thiab molybdenum rau cov hlau-carbon alloy. Hlau feem ntau duller dua stainless hlau. Nws tseem yog magnetic thiab muaj qib siab ntawm malleability.
Galvanized steel yog coated nrog ib txheej ntawm zinc uas muab nws corrosion resistant zoo. Txawm hais tias peb muab galvanized steel vaj tse, cov hlau no muaj kev cuam tshuam los ntawm cov dej ntsev. Thov nco ntsoov tias galvanized steel yog kim dua thiab hnyav dua stainless hlau.
