Qhov sib txawv ntawm 904 stainless hlau xaim mesh thiab 904L stainless hlau xaim mesh yog qhov tseem ceeb hauv cov hauv qab no:
Tshuaj muaj pes tsawg leeg:
· Txawm hais tias 904 stainless hlau xaim mesh muaj cov yam ntxwv corrosion-resistant ntawm austenitic stainless hlau, cov tshuaj muaj pes tsawg leeg tshwj xeeb tsis tau hais txog qhov nthuav dav hauv tsab xov xwm siv.
· 904L stainless hlau hlau mesh (tseem hu ua super austenitic stainless hlau) muaj cov tshuaj muaj pes tsawg leeg. Nws muaj 14.0% mus rau 18.0% chromium, 24.0% mus rau 26.0% npib tsib xee, thiab 4.5% molybdenum. Qhov siab nickel thiab siab molybdenum muaj pes tsawg leeg muab nws zoo heev corrosion kuj.
Corrosion kuj:
Ob leeg muaj kev tiv thaiv corrosion zoo, tab sis 904L stainless hlau xaim mesh muaj kev tiv thaiv corrosion zoo dua. Tshwj xeeb, nws muaj kev tiv thaiv zoo rau cov tsis-oxidizing acids xws li sulfuric acid, acetic acid, formic acid, phosphoric acid, thiab lwm yam, thiab nthuav tawm zoo tiv thaiv pitting, crevice corrosion thiab kev ntxhov siab corrosion hauv nruab nrab chloride ion media.
Hauv qhov sib piv, txawm hais tias qhov kev tiv thaiv corrosion ntawm 904 stainless hlau xaim mesh kuj muaj zog heev, cov ntaub ntawv tshwj xeeb thiab ntau yam tsis tau hais hauv tsab xov xwm siv.
Mechanical zog:
904L stainless hlau xaim mesh muaj lub zog siab thiab hardness, nrog rau zoo plasticity thiab toughness. Cov khoom siv kho tshuab no ua rau nws ua tau raws li ntau yam kev siv tshuab thiab kev tsim khoom.
Hais txog cov khoom siv kho tshuab ntawm 904 stainless hlau xaim mesh, cov ntaub ntawv tshwj xeeb tsis tau hais meej meej hauv tsab xov xwm siv.
Kev siv thaj chaw:
Vim nws zoo heev corrosion kuj thiab mechanical zog, 904L stainless hlau hlau mesh feem ntau siv nyob rau hauv hnyav ua hauj lwm ib puag ncig, xws li roj av, petrochemical khoom, flue roj desulfurization li nyob rau hauv fais fab nroj tsuag, offshore systems los yog seawater kho.
· 904 stainless hlau hlau mesh muaj corrosion kuj thiab siv tau nyob rau hauv corrosion-resistant teb.
· 904L stainless hlau xaim mesh muaj kev ua tau zoo dua li 904 stainless hlau xaim mesh nyob rau hauv cov nqe lus ntawm cov tshuaj muaj pes tsawg leeg, corrosion kuj, txhua yam khoom thiab vuam kev ua tau zoo, yog li nws yog feem ntau siv nyob rau hauv ntau xav tau kev pab ua hauj lwm ib puag ncig.
