S320GD Galvanized hlau
Kub dip galvanized S320GD steel yog siab - lub zog steel. "320" qhia qhov tsawg kawg nkaus tawm lub zog ntawm 320 MPa. S320GD steel yog dav lees paub rau nws zoo heev formability, lub zog, thiab superior corrosion tiv thaiv. Nws tuaj yeem tsim los ntawm kub dov thiab txias dov, nrog rau kev kho kub dip galvanizing. Nws yog dav siv hauv kev lag luam xws li tsheb tsim thiab kev lag luam hauv tsev.
GNEE STEEL muab S320GD nyob rau hauv daim ntawv ntawm coils thiab strips, kom ntseeg tau siab - cov khoom zoo rau ntau yam haujlwm.
S320GD steel chemical muaj pes tsawg leeg yog tailor- ua rau siab durability thiab corrosion kuj, thiab yog li zoo rau cov qauv siv. Nws feem ntau muaj cov pa roj carbon tsawg, manganese, phosphorus, thiab sulfur qib kom sib npaug ntawm lub zog thiab kev ua haujlwm. S320GD tau txhim kho cov khoom siv galvanization los ntawm zinc txheej, muab kev tiv thaiv ntau dua tiv thaiv ib puag ncig hnav thiab corrosion thaum piv nrog rau lwm qib steel xws li S235 lossis S355. Qhov tshwj xeeb thaj ntawm qhov zoo no muab nws ib txheej ntawm cov yam ntxwv uas ua rau nws muaj kev xaiv zoo hauv kev tsim kho thiab hauv kev tsim khoom.
Kev cuam tshuam ntawm cov tshuaj muaj pes tsawg leeg ntawm Corrosion Resistance
Cov txheeb ze tshuaj muaj pes tsawg leeg ntawm ib tug alloy txiav txim siab corrosion kuj ntawm ib tug compound, lub tom kawg ua hauj lwm nyob rau hauv ib tug theem pib los tiv thaiv ib tug alloy tiv thaiv undesirable cov neeg sawv cev nyob rau hauv lub sab nraud ib puag ncig. Hauv qab no yog cov lus piav qhia ntawm tsib feem ntau cov ntsiab lus thiab lawv cov kev cuam tshuam ntawm corrosion kuj:
Chromium-Chromium tseem yog qhov tseem ceeb tshaj plaws rau kev tiv thaiv corrosion hauv stainless hlau. Nws tsim ib tug passive nto oxide txheej uas inhibits oxidation ntxiv. Yog li ntawd, alloys feem ntau muaj tsawg kawg yog 10.5% chromium kom them taus corrosion txaus.
Nickel- Ntxiv nickel muab kev ruaj ntseg thiab tawv thiab tiv taus pitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv marine thiab acidic ib puag ncig.
Molybdenum-Molybdenum muaj qee qhov pitting tsis kam nyob rau hauv chloride ib puag ncig zoo li dej hiav txwv. Alloys nrog 2-3% molybdenum ua tau zoo nyob rau hauv siab salinity.
Cov pa roj carbon- Cov pa roj carbon yuav tsum muaj zog; Txawm li cas los xij, siab - carbon steels yog qhov sib piv tsawg dua corrosion resistant, vim chromium retention yog txo vim yog tsim ntawm chromium carbides. Cov ntsiab lus carbon yog khaws cia hauv cov hlau tsis muaj steel, xws li qis- qib carbon, kom muaj kev tiv thaiv corrosion zoo.
Nitrogen-Nitrogen ua kom cov hlau tsis muaj zog tiv taus pitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv qib duplex. Tsis tas li ntawd, nitrogen ua kom cov khoom siv kho kom zoo dua qub, sib txuas lub zog thiab ductility.
Nta
S320GD galvanized steel tuaj yeem nqa cov txiaj ntsig hauv qab no rau koj qhov project:
Tawv tiv thaiv xeb- Sawv ntsug rau huab cua thiab tsis xeb yooj yim.
Ntev ntev- Cov txheej zinc ua kom nws ruaj khov rau xyoo.
Super Strong- Tsim los ua haujlwm hnyav - cov haujlwm tsis muaj dabtsi yog khoov lossis tawg.
Txuag Nyiaj- Tsawg dua yuav tsum tau saib xyuas, yog li nws raug nqi - zoo.
Ntau-Lub Hom Phiaj- Haum rau ntau yam kev siv, los ntawm lub tsev mus rau lub tsheb.
Yooj yim rau Zoo- Yooj yim txaus rau txhua yam haujlwm.
Yooj yim rau Weld- Ua haujlwm zoo nrog vuam, yog li tsis muaj teeb meem hauv kev tsim khoom.
Saib kom huv- Smooth nto uas zoo nkaus li zoo nyob rau hauv pom daim ntaub ntawv.
