Muaj ntau pua qib sib txawv ntawm stainless hlau nyob rau hauv kev ua lag luam.Txhua qhov tshwj xeeb formulations ntawm stainless hlau muaj qee qhov kev tiv thaiv corrosion saum toj no thiab dhau ntawm cov hlau dawb.
Qhov muaj nyob ntawm cov hlau tsis sib xws no tuaj yeem ua rau qee qhov tsis meej pem - tshwj xeeb tshaj yog thaum cov npe & cov qauv ntawm ob lub stainless hlau alloys yuav luag tib yam.Qhov no yog cov ntaub ntawv nrog qib 304 thiab 304L stainless hlau.
Qeb 304 SS Chemical Cov ntsiab lus los ntawm % Qib 304L SS Cov ntsiab lus tshuaj lom neeg los ntawm %

Sulfur 0.030 Max 0.030 Max
Ob lub alloys no zoo sib xws - tab sis muaj ib qho tseem ceeb sib txawv.Hauv qib 304 stainless hlau, qhov siab tshaj plaws cov ntsiab lus yog teem rau ntawm 0.08%, thaum qib 304L stainless hlau muaj cov ntsiab lus siab tshaj plaws ntawm 0.03%.Qhov "L" hauv 304L tuaj yeem txhais tau tias lub ntsiab lus ntxiv-tsawg carbon.
Qhov sib txawv ntawm 0.05% carbon cov ntsiab lus no ua rau me ntsis, tab sis cim, qhov sib txawv ntawm kev ua yeeb yam ntawm ob lub alloys.
Qhov txawv Mechanical
Qib 304L muaj me ntsis, tab sis pom tau, txo qis hauv cov yam ntxwv ntawm kev ua haujlwm tseem ceeb piv rau "tus qauv" qib 304 stainless hlau alloy.
Piv txwv li, qhov kawg tensile lub zog (UTS) ntawm 304L yog kwv yees li 85 ksi (~ 586 MPa), tsawg dua UTS ntawm qib 304 stainless, uas yog 90 ksi (~ 620 MPa).Qhov sib txawv ntawm lub zog tawm los yog me ntsis ntau dua, nrog 304 SS muaj 0.2% yield zog ntawm 42 ksi (~ 289 MPa) thiab 304L muaj 0.2% yield zog ntawm 35 ksi (~ 241 MPa).
Qhov no txhais tau hais tias yog tias koj muaj ob lub pob tawb steel hlau thiab ob lub pob tawb muaj qhov tsim tib yam, hlau tuab, thiab kev tsim kho, lub pob tawb ua los ntawm 304L yuav tsis muaj zog dua li tus qauv 304 pob tawb.
Vim li cas Koj Thiaj Xav Siv 304L, Tom qab ntawd?
Yog li, yog tias 304L tsis muaj zog dua li tus qauv 304 stainless hlau, vim li cas leej twg xav siv nws?
Cov lus teb yog tias 304L alloy cov ntsiab lus qis carbon yuav pab txo qis / tshem tawm cov nag lossis daus carbide thaum lub sijhawm vuam.Qhov no tso cai rau 304L stainless hlau siv nyob rau hauv lub xeev "raws li-welded", txawm nyob rau hauv ib puag ncig corrosive hnyav.
Yog tias koj yuav tsum siv tus qauv 304 stainless tib txoj kev, nws yuav degrade sai dua ntawm cov pob qij txha.
Yeej, siv 304L tshem tawm qhov yuav tsum tau muab cov pob qij txha txuas ua ntej siv cov hlau ua tiav-txuag lub sijhawm thiab kev siv zog.
Hauv kev xyaum, ob qho tib si 304 thiab 304L tuaj yeem siv rau ntau daim ntawv thov tib yam.Qhov sib txawv feem ntau me me txaus uas ib qho tsis suav tias muaj txiaj ntsig ntau dua li lwm tus.Thaum muaj zog corrosion kuj xav tau, lwm yam alloys, xws li qib 316 stainless hlau, feem ntau suav hais tias yog lwm txoj hauv kev.
