Galvanized Steel Chev
Kub-dip galvanized steel S250GD raws li EN 10346 tus qauv yog siab-cov qauv hlau zoo uas tau tsim tshwj xeeb rau kev siv hauv kev tsim kho. Nrog rau cov khoom siv tooj 1.0242, S250GD muaj qhov tsawg kawg nkaus yield zog Rp0.2 ntawm 250 N / mm² thiab yog li muab faib nyob rau hauv nruab nrab lub zog chav kawm ntawm kub -dip galvanized structural steels. EN 10346 tus qauv tsis tsuas yog qhia txog cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab, tab sis kuj txhais cov txheej txheem kub -dip galvanizing uas tsim kom muaj kev tiv thaiv ib puag ncig zinc txheej ntawm cov hlau. Cov txheej txheej muaj + Z, + ZF, + ZA, + ZM, + AZ thiab + AS ua kom muaj kev yoog raws qhov sib txawv ntawm ib puag ncig thiab cov xwm txheej thauj khoom.

Cov txheej txheem ntau lawm rau galvanized steel yog raws li nram no.
Gulping ib daim hlau rau hauv ib lub vat ntawm molten zinc yog txheej txheem uas tsim cov hlau galvanized. Thaum cov zinc melts, nws tsim ib txheej tiv thaiv uas lo rau cov hlau. Ob txoj hauv kev zoo tshaj plaws rau galvanize steel yog electrogalvanizing thiab kub -dip galvanizing.
Ib qho txheej txheem yog kub -dip galvanizing. Txhawm rau ua kom kub -dip galvanizing, cov nplooj ntawv steel yog rhuab mus txog 800 degrees Fahrenheit thiab tom qab ntawd muab tso rau hauv ib da dej ntawm zinc molten. Ib qho kwv yees li 0.002 txog 0.006 nti tuab txheej ntawm cov zinc melted yog tsim.
Tsawg feem ntau siv yog electrogalvanizing. Ib da dej ntawm zinc ions yog siv los electrogalvanize cov ntawv hlau. Los ntawm kev hla cov hluav taws xob tam sim no los ntawm cov hlau, zinc ions tau tso rau ntawm nws qhov chaw. Ntawm 0.0002 thiab 0.0005 ntiv tes tuab yog zinc txheej.
S250GD Galvanized Steel Qhov Zoo
Peb S250GD galvanized steel excels nyob rau hauv lub zog, durability thiab processability, pab cov neeg muas zaub tau yooj yim raws li ntau yam kev xav tau nyob rau hauv kev tsim kho thiab manufacturing teb nrog kev ua tau zoo thiab tus nqi -effectiveness:
Siab zog thiab zoo stability:S250GD lav lub zog tawm ntawm yam tsawg kawg 250 MPa, uas tuaj yeem tswj cov qauv kev ruaj ntseg nyob rau hauv siab loads, thaum muaj ntau yam khoom zoo sib xws yog me ntsis tsis muaj zog.
ductility zoo heev thiab haum rau kev tsim:S250GD muaj qhov ntev dua tom qab tawg dua li cov hlau zoo tib yam ntawm kev ua lag luam, thiab tsis yooj yim rau tawg thaum lub sij hawm tsim, ua rau nws tsim nyog rau kev ua haujlwm nyuaj.
Zoo heev corrosion kuj:Peb tau ua kom zoo dua cov txheej txheem galvanizing los xyuas kom meej tias cov hlau tuaj yeem siv tau ntev hauv qhov chaw ntub dej lossis cov chaw muaj kuab paug, txo qis corrosion, thaum lwm yam khoom muaj lub neej luv luv hauv cov cheeb tsam no.
Zoo weldability thiab kev tsim kho yooj yim dua:Nws tuaj yeem ua tau yooj yim welded yam tsis muaj preheating, txuag lub sij hawm tsim kho thiab nqi, thaum lwm yam ntaub ntawv feem ntau xav tau ntau txheej txheem.
Environmentally sustainable:S250GD muaj tus nqi rov ua dua tshiab thiab ua tau raws li cov qauv kev tsim khoom ntsuab, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm zoo ib puag ncig.
