1. Kev sib xyaw:
304L Stainless Hlau Yeeb Nkab: 304l yog austenitic stainless hlau uas muaj kwv yees li 18-20 feem pua chromium thiab 8-12 feem pua npib tsib xee. Nws kuj muaj cov ntsiab lus carbon tsawg, feem ntau nyob ib ncig ntawm 0.03 feem pua, uas pab txhim kho corrosion kuj thiab txo qhov kev pheej hmoo ntawm rhiab heev thaum vuam.
904L Stainless hlau yeeb nkab: 904l stainless hlau kuj yog qib austenitic stainless hlau tab sis nrog cov ntsiab lus siab dua. Nws muaj kwv yees li ntawm 19-23 feem pua chromium, 24-26 feem pua nickel, 4-5 feem pua molybdenum, thiab 1-2 feem pua tooj. Qhov sib ntxiv ntawm tooj liab ua rau nws tsis kam ua kom muaj zog txo cov acids xws li sulfuric acid.
2. Corrosion kuj:
304L Stainless hlau yeeb nkab: 304L stainless hlau yeeb nkab muaj qhov zoo ntawm corrosion kuj nyob rau hauv ib puag ncig me me, nrog rau atmospheric tej yam kev mob thiab ntau yam organic thiab inorganic tshuaj. Txawm li cas los xij, nws tsis tshua muaj corrosive ib puag ncig dua li 904L stainless hlau.
904L Stainless Hlau Yeeb Nkab: 904l stainless hlau yeeb nkab muaj kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig corrosive xws li sulfuric acid, phosphoric acid, thiab cov tshuaj chloride. Nws yog heev resistant rau pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking.
3. Daim ntawv thov:
304L Stainless Hlau Yeeb Nkab: Siv dav hauv ntau yam kev lag luam nrog rau kev ua zaub mov, kev ua tshuaj, thiab tshuaj. Haum rau cov ntawv thov uas xav tau kev tiv thaiv corrosion thiab zoo formability.
904L Stainless Hlau Yeeb Nkab: feem ntau siv hauv cov khoom siv dej hiav txwv, cov chaw sab nrauv, cov nroj tsuag tshuaj, kev lag luam tshuaj, thiab lwm yam uas yuav tsum tau muaj kev tiv thaiv corrosion. Nws kuj yog siv rau hauv kev tsim cov cua kub exchangers, condenser raj, thiab sulfuric acid kho khoom.
4. Nqe:
304L Stainless Hlau Yeeb Nkab: Nws feem ntau siv nyiaj ntau dua li 904L stainless hlau, ua rau nws muaj kev xaiv nrov rau ntau daim ntawv thov.
904L Stainless Hlau Tube: Qhov no yog cov khoom siv kim dua vim nws cov ntsiab lus alloy siab dua, tshwj xeeb tshaj yog qhov sib ntxiv ntawm tooj liab, uas ua rau nws zoo heev corrosion kuj.
