◉Nyob rau hauv lub neej niaj hnub, stainless hlau tau dhau los ua cov khoom siv tseem ceeb thiab siv dav hauv kev tsim kho, tsim khoom thiab lub neej txhua hnub. Muaj ntau ntau hom stainless hlau, nrog rau cov qauv siv xws li 201, 304 thiab316.
Txawm li cas los xij, rau cov neeg uas tsis nkag siab txog cov khoom ntawm cov khoom, nws yog ib qho yooj yim kom tsis meej pem los ntawm qhov sib txawv ntawm cov qauv no. Kab lus no yuav qhia txog qhov sib txawv ntawm stainless hlau 201, 304 thiab 316 los pab cov neeg nyeem kom nkag siab zoo txog cov qauv sib txawv ntawm cov ntaub ntawv stainless hlau thiab muab qee cov lus qhia rau kev yuav khoom stainless hlau.
◉Ua ntej, qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm stainless hlau yog qhov tseem ceeb hauv kev txiav txim siab nws cov kev ua tau zoo thiab cov yam ntxwv.Stainless hlau 201, 304 thiab 316 muaj qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg. Stainless hlau 201 muaj 17.5% -19.5% chromium, 3.5% -5.5% nickel, thiab 0.1% -0.5% nitrogen, tab sis tsis muaj molybdenum.
Stainless hlau 304, ntawm qhov tod tes, muaj 18% -20% chromium, 8% -10.5% nickel, thiab tsis muaj nitrogen lossis molybdenum. Hauv qhov sib piv, stainless hlau 316 muaj 16% -18% chromium, 10% -14% nickel, thiab 2% -3% molybdenum. Los ntawm cov tshuaj muaj pes tsawg leeg, stainless hlau 316 muaj ntau dua corrosion kuj thiab acid tsis kam, haum rau siv nyob rau hauv tej qhov chaw tshwj xeeb tshaj stainless hlau 201 thiab 304.
◉Qhov thib ob, qhov sib txawv ntawm corrosion kuj
Corrosion kuj yog ib qho tseem ceeb ntawm kev ua tau zoo ntawm stainless hlau. Stainless hlau 201 muaj corrosion kuj zoo rau feem ntau cov organic acids, inorganic acids thiab ntsev daws nyob rau hauv chav tsev kub, tab sis yuav corroded nyob rau hauv ib tug muaj zog alkaline ib puag ncig. Stainless hlau 304 muaj qhov zoo corrosion kuj thiab haum rau feem ntau corrosive ib puag ncig.
Stainless hlau 316, ntawm qhov tod tes, excels nyob rau hauv corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv acidic ib puag ncig thiab high-temperature tej yam kev mob nrog zoo heev corrosion kuj, feem ntau siv nyob rau hauv tshuaj, marine thiab lwm yam kev siv. Yog li ntawd, thaum mus yuav khoom rau cov khoom siv hlau tsis muaj steel, nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov qauv zoo raws li kev siv tshwj xeeb ntawm qhov chaw sib txawv.
◉Thib peb, qhov sib txawv ntawm cov khoom siv kho tshuab
Cov yam ntxwv ntawm cov hlau tsis muaj steel muaj xws li ntsuas lub zog, ductility thiab hardness. Feem ntau hais lus, lub zog ntawm stainless hlau 201 yog me ntsis siab dua li ntawm stainless hlau 304, tab sis qis dua li ntawm stainless hlau 316.Stainless steel 201 thiab 304 muaj ductility zoo, yooj yim rau txheej txheem thiab molding, haum rau ib co ntawm cov khoom. ua cov kev xav tau ntawm kev ua haujlwm siab dua.
Lub zog siab dua ntawm stainless hlau 316, tab sis kuj muaj kev hnav zoo thiab tensile tsis kam, haum rau kev tiv taus siab zog thiab kub kub ua haujlwm. Yog li ntawd, thaum xaiv cov ntaub ntawv stainless hlau, koj yuav tsum xaiv qhov tsim nyog raws li cov kev xav tau tshwj xeeb thiab kev siv ib puag ncig.
◉Plaub, tus nqi sib txawv
Kuj tseem muaj qee qhov sib txawv ntawm tus nqi ntawm stainless hlau 201, 304 thiab 316. Feem ntau hais lus, tus nqi ntawm stainless hlau 201 yog tus nqi qis, pheej yig dua. Tus nqi ntawm stainless hlau 304 yog qhov siab, tab sis vim nws cov kev siv ntau thiab kev ua tau zoo tag nrho, nws tseem yog ib qho ntawm cov qauv stainless hlau feem ntau ntawm kev ua lag luam.
◉ Stainless hlau 316 kuj tseem kim vim nws zoo corrosion kuj thiab txhua yam khoom, thiab yog haum rau qee qhov tshwj xeeb teb uas xav tau cov khoom siv siab. Yog li ntawd, thaum yuav cov khoom siv stainless hlau, koj yuav tsum xav txog yam xws li cov khoom siv thiab kev siv nyiaj txiag.
Raws li tus kws tshaj lij ntawm cov khoom siv hlau stainless, Shanghai Qinkai Industry Co.
Lub Hoobkas tau tsim nyob rau hauv 2014, thiab tom qab xyoo ntawm txoj kev loj hlob, nws tau dhau los ua ib lub tuam txhab ua ke nrog kev muag khoom ntawm cov phaj, raj thiab cov profiles.
Ua raws li txoj cai ntawm cov neeg siv khoom ua ntej,Qinkaitau cog lus los muab cov neeg siv khoom nrog cov khoom zoo stainless hlau thiab cov kev pabcuam zoo heev!
