Q195 steel yog dab tsi?
Q195 yog cov pa roj carbon monoxide zoo tib yam, muaj nyob rau hauv qeb ntawm qis- carbon steel. "Q" sawv cev rau lub zog tawm los, thiab "195" txhais tau hais tias lub zog tawm los yog ntau dua lossis sib npaug rau 195MPa thaum lub thickness tsawg dua lossis sib npaug li 16 hli. Nws yog ib qho kev siv thiab kev lag luam steel hauv kev tsim kho kev lag luam.
Cov qauv rau Q195 yog dab tsi?
Nws ua raws li GB / T 700-2006 "Carbon Structural Steel." Cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov khoom xa tuaj yuav tsum tau ua raws li cov qauv no.
Dab tsi yog qhov txawv ntawm Q195 thiab Q235?
Q195 muaj lub zog qis dua (Q195 Ntau dua lossis sib npaug ntawm 195MPa, Q235 Ntau dua lossis sib npaug ntawm 235MPa), zoo dua plasticity thiab weldability, thiab tus nqi qis dua, tab sis tsis muaj zog load-cov kabmob muaj peev xwm, ua rau nws tsuas yog tsim rau cov khoom siv hauv tsev thib ob.
Dab tsi yog carbon cov ntsiab lus ntawm Q195?
Cov ntsiab lus carbon yog 0.06% -0.12%. Nws cov yam ntxwv qis-carbon txiav txim siab nws cov plasticity zoo heev thiab weldability, uas yog cov txiaj ntsig zoo hauv kev tsim kho.
Lub sijhawm xa khoom rau Q195 yog dab tsi?
Feem ntau yog kub- dov, tab sis txias- dov, galvanized, thiab xim- coated finishes kuj muab tau los ua kom tau raws li cov kev xav tau ntawm ntau yam kev tsim kho scenarios.
