Ntawm qhov sib txawv ntawm cov hlau stainless, qib 304, 304L, thiab 304H feem ntau siv. Thaum lawv yuav zoo ib yam li, txhua qib muaj nws tus kheej cov khoom sib txawv thiab cov ntawv thov.
Teem nqi304 Stainless Hlauyog qhov dav tshaj plaws siv thiab ntau yam ntawm 300 series stainless hlau. Nws muaj 18-20% chromium thiab 8-10.5% npib tsib,5% npib tsib, nrog rau cov pa roj carbon, manganese, thiab silicon. Cov qib kawm no muaj zoo heev corrosion tsis kam thiab muaj kev muaj zog zoo. Nws yog feem ntau siv nyob rau hauv cov ntawv thov xws li chav ua noj khoom siv, kev ua zaub ua khoom noj ua khoom kom zoo nkauj.
304L Stainless Hlau Yeeb Nkabyog cov roj carbon steel yeeb nkab sib txawv ntawm qib 304, nrog cov ntsiab lus carbon ntau ntawm 0.03%. Cov ntsiab lus carbon tsawg no pab txo qis carbide nag lossis daus thaum lub sij hawm vuam, ua kom haum rau vuam cov ntawv thov. Cov ntsiab lus ntawm cov roj carbon qis kuj yuav txo cov kev pheej hmoo ntawm cov chromium carbides ntawm cov ciaj ciam av, uas tuaj yeem ua rau muaj kev sib tshuam. 304L feem ntau siv nyob rau hauv vuam cov ntawv thov, nrog rau ib puag ncig cov kev pheej hmoo ntawm corrosion yog kev txhawj xeeb thiab cov khoom siv tshuaj lom neeg.
304h Stainless Hlauyog cov pa roj carbon ntau dua ntawm qib 304, nrog cov ntsiab lus roj carbon monox nyom los ntawm 0.04-0.10%. Cov ntsiab lus carbon ntau dua muab cov khoom kub zoo dua siab dua thiab siv tau. Qhov no ua rau 304h haum rau cov ntawv thov kub siab, xws li cov hlab ntsha siab, kev hloov pauv kub, thiab muaj boilers. Txawm li cas los xij, cov ntsiab lus carbon ntau dua kuj ua rau 304h ntau raug rau cov kev paub thiab kev txhim kho corrosion, tshwj xeeb tshaj yog nyob hauv vuam cov ntawv thov.
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm cov qib no yog lawv cov ntsiab lus carbon thiab cov nyhuv ntawm vuam thiab cov kev siv kub siab. Qeb 304 yog cov hom phiaj siv dav dav thiab dav dav, thaum 304l yog qhov kev xaiv vuam thiab ib thaj chaw uas muaj kev txhawj xeeb uas muaj kev txhawj xeeb. 304H muaj cov ntsiab lus muaj roj carbon ntau dua thiab yog haum rau cov kev siv kub siab, tab sis nws yuav tsum tau txais kev saib xyuas zoo. Thaum xaiv tau ntawm cov qib kawm no, nws yog ib qho tseem ceeb kom xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov, suav nrog kev ua haujlwm hauv chaw ua haujlwm, ntsuas kub, thiab xav tau vuam xav tau, thiab xav tau vuam.
