1.Q355b Dab tsi yog cov khoom muaj peev txheej ntawm cov hlau galvanized?
Lub Zog Siab: Q355B Steel muaj ib qho txiaj ntsig lub zog ntawm tsis muaj tsawg dua 355mpa thiab lub zog tensile nruab nrab ntawm 490-675MPA. Nws lub zog siab thiab lub zog ua rau nws tiv taus lub siab zoo thiab cuam tshuam, tiv thaiv deform lossis tawg. Nws tuaj yeem siv rau hauv cov txheej txheem cov khoom sib xyaw cov kabmob siab.
Cov tawv ntoo zoo: Q355B cov khoom ua pov thawj zoo tshaj plaws - kub huv, nrog ib tug elongation ntawm ntau dua los yog sib npaug rau 22%. Nws tswj hwm cov kev cuam tshuam zoo txawm txawm nyob hauv qis -} sov ib puag ncig, ua kom haum rau cov haujlwm tsim kho hauv cov cheeb tsam txias.
High corrosion Kuj: Los ntawm kub - dip galvanizing txheej, zinc txheej yog tsim ntawm cov hlau deg. Cov txheej no cais cov hlau los ntawm cov chaw nyob sab nraud, tiv thaiv xeb thiab ua kom muaj kev pabcuam ntev txawm nyob hauv ib puag ncig hnyav.
Zoo machinability: q355B galvanized steel lees txais zoo heev weldability thiab ob lub zog kub thiab txias, ua rau nws txiav yooj yim, khoov, thiab weld. Nws tuaj yeem tsim los ua ntau yam duab kom tau raws li qhov xav tau ntawm cov haujlwm sib txawv.
2.What yog cov tshuaj lom neeg muaj kuab lom ntawm Q355B Galvanized steel?
Cov khoom siv tseem ceeb ntawm Q355B galvanized steel muaj tsawg dua lossis sib npaug lossis sib npaug lossis sib npaug lossis sib npaug lossis sib npaug lossis 0.60%, v 0.02-0.15%, thiab nb 0.015-0.06%.
3.Q3555Txawm cov txheej txheem ntawm cov txheej txheem galvanized yog dab tsi?
Q355B Steel yog feem ntau ua tiav rau hauv cov duab uas xav tau, xws li cov hlau steel lossis cov kav dej, ua ntej galvanized. Muaj ob lub ntsiab galvanizing: kub- dip galvanizing thiab txias}} dip galvanizing. Kub - dip galvanizing muaj feem cuam tshuam rau cov hlau hauv Molten zinc, sib sau cov txheej zinc Cov txheej no yog cov khaub ncaws zoo nkauj, muaj cov nplaum nplaum muaj zog, thiab muab cov tshuaj tsw qab muaj zog. Txias -} dip galvanizing, ntawm qhov tod tes, koom nrog electroplating cov steel saum npoo nrog tus nqi me me ntawm kev ua kom haum corrosion.
4.What yog cov ntawv thov ntawm Q355B galvanized steel?
Kev Tsim Kho: Nws tuaj yeem siv los txhawb thiab tiv thaiv kev teeb tsa tsev, cov neeg tiv thaiv cov cuab yeej stuss, thiab cov vaj tse stusses thiab kev nyab xeeb ntawm cov tsev.
Tsheb thauj mus los: Nws yog ib qho siv hauv kev tsim cov chaw thauj mus los, xws li cov neeg zov txoj kev tsheb thauj mus los, choj qauv, thiab qhov chaw tsheb. Nws lub zog siab thiab corrosion tsis kam muab kev tiv thaiv zoo heev thiab txhawb nqa.
Petrochemical: Nws yog dav siv nyob rau hauv cov roj thiab roj roj pipelines thiab cov khoom siv tshuaj lom neeg. Nws zoo heev corrosion tsis kam thiab cov khoom sib khi ua kom muaj kev nyab xeeb ntawm cov kav dej thiab khoom siv.
5.Qhov yog tus nqi lag luam ntawm Q355B galvanized steel?
Tus nqi ntawm Q355B galvanized steel yog cuam tshuam los ntawm cov khoom xws li kev ua lag luam thiab cov khoom siv khoom siv tau, thiab cov txheej txheem ntau lawm.
