galvanized steel phaj
Nrhiav kev ntseeg siab S550GD galvanized steel phaj manufacturers hauv Suav teb? Koj twb tuaj rau qhov zoo lawm. Raws li lub Hoobkas ncaj qha nrog 20 xyoo ntawm kev tsim steel hlau, GNEE Steel khoom siv EN 10346 rawsS550GD galvanized steel phajntawm Hoobkas nqi. Cov lus qhia no tshawb txog cov yam ntxwv tseem ceeb ntawm S550GD steel thiab vim li cas nws yog qhov zoo tagnrho rau cov ntawv thov.
Galvanized steel yog carbon hlau kho nrog zinc txheej los txhim kho corrosion kuj. Nws tau dav siv hauv kev tsim kho, kev tsim tsheb, thiab cov cuab yeej siv vim nws cov kav ntev thiab tus nqi -effectiveness. Cov qib galvanized steel feem ntau suav nrog S235GD rau kev siv dav dav, S350GD rau nruab nrab- qhov xav tau muaj zog, thiab siab - kev ua tau zooS550 GDuas stands rau nws exceptional zog thiab formability.

Chemical Composition Yam ntxwv ntawm S550GD Steel
Cov tshuaj muaj pes tsawg leeg ntawmS550GD galvanized steel phajyog ua tib zoo sib npaug kom xa cov kev ua tau zoo. Cov ntsiab lus carbon yog txwv tsawg dua lossis sib npaug li 0.12% kom ntseeg tau tias weldability thiab formability thaum tuav lub zog siab. Manganese, tsawg dua lossis sib npaug li 2.00%, txhim kho lub zog tensile yam tsis muaj kev cuam tshuam ductility.
Silicon, khaws cia tsawg dua lossis sib npaug li 0.50%, txhim kho cov khoom teb rau galvanization, kom ntseeg tau tias cov txheej txheej adhesion. Phosphorus thiab sulfur yog tswj nruj me ntsis (tsawg dua los yog sib npaug rau 0.030% thiab Tsawg dua los yog sib npaug rau 0.025% feem) kom txo qis brittleness thiab defects. Aluminium, tam sim no ntawm Ntau dua los yog sib npaug rau 0.015%, refines cov qauv lis, txhim kho ob lub zog thiab formability.
Qhov muaj pes tsawg leeg no tso cai rau S550GD los tswj nws cov qauv kev ntseeg siab nyob rau hauv kev ntxhov siab thaum muab qhov zoo tagnrho rau zinc txheej adhesion. Nws kuj ua kom muaj kev sib raug zoo nrog ntau yam txheej txheem fabrication, los ntawm dabtsi yog khoov mus rau vuam.
Mechanical Performance Yam ntxwv ntawm S550GD
S550GD galvanized steel phajnthuav tawm cov yam ntxwv zoo heev uas ua rau nws haum rau siab - kev siv kev ntxhov siab. Nws qhov tsawg kawg nkaus tawm lub zog ntawm 550 MPa muab cov khoom zoo heev - cov kabmob muaj peev xwm, ua rau nws zoo tagnrho rau cov khoom siv uas xav tau lub zog tsis muaj qhov hnyav hnyav.
Lub zog tensile ntau ntawm 600-730 MPa ua kom tsis txhob ncab thiab deformation nyob rau hauv hnyav loads. Txawm hais tias nws lub zog siab, S550GD tuav cov ductility zoo nrog qhov elongation tus nqi ntau dua lossis sib npaug li 14%, tso cai rau kev tsim thiab khoov yam tsis muaj kev tawg-ib qho tseem ceeb rau cov txheej txheem tsim khoom.
Hauv kev ntsuam xyuas qhov cuam tshuam, S550GD ua kom pom ntau dua lossis sib npaug ntawm 27 J ntawm lub zog cuam tshuam ntawm -40 degree, ua pov thawj nws cov kav ntev hauv qhov chaw kub qis. Cov khoom siv kuj ua tau zoo hauv kev sim khoov, nrog rau 180℃khoov yam tsis muaj kev tawg, txawm tias tom qab galvanization.
Corrosion Resistance yam ntxwv
Ib tug yam ntxwv tseem ceeb ntawmS550GD galvanized steel phajyog nws zoo heev corrosion kuj, ua tsaug rau kub-dip zinc txheej. Lub zinc txheej ua raws li kev txi anode, tiv thaiv cov hlau hauv qab los ntawm xeb thiab corrosion.
Cov txheej txheej, xws li Z60 (60 g / m²) txog Z275 (275 g / m²), tso cai rau kev hloov kho raws li ib puag ncig. Nyob rau hauv ib puag ncig me me, Z100-Z140 txheej txheej muab kev tiv thaiv txaus, thaum hnyav marine lossis kev lag luam ib puag ncig tau txais txiaj ntsig los ntawm Z200-Z275 txheej.
Cov tshuaj tsuag tshuaj ntsev tau lees paub tias S550GD nrog Z275 txheej tuaj yeem tiv taus ntau dua 500 teev ntawm kev kis tsis muaj xeb liab. Qhov kev tiv thaiv corrosion no cuam tshuam rau cov khoom siv lub neej, txo cov nqi kho thiab hloov zaus.
Qhov tshwj xeeb lub zog, formability, thiab corrosion kuj yam ntxwv ntawmS550GD galvanized steel phajua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev thov kev thov. GNEE Steel muab siab -S550GD cov khoom zoo uas ua tau raws li EN 10346 tus qauv.Tiv tauj peb rau qhov tseeb 2026 daim ntawv teev nqi thiab cov kev qhia tshwj xeeb rau S550GD galvanized steel phaj.
