GB / T Q235Nhub Huab Cua Hlau
Raws li cov chav tsev huab cua tshaj plaws hauv Suav txoj siv thiab txoj kev siv ntom, nws txhim kho cov nqi xeb uas txo qis xeb ntawm cov hlau 80% piv rau cov pa roj carbon hlau. Qhov kev daws teeb meem zoo no tau ntsib GB / T 4171-2008 tus qauv thaum muaj cov txiaj ntsig tshwj xeeb rau ib puag ncig chaw kub thiab muaj kev lag luam.
Khoom Piav Qhia
1. Neeg Esxias Kev Nyab Xeeb-}} qhov kev ua tau zoo
Monsoon - tiv taus patina: Cov ntsiab lus phosphorus tshwj xeeb (0.07- 0.15%) accelerates txheej txheem kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv hnyav
Kev Tiv Thaiv Kev Nyab Xeeb Kev Tiv Thaiv: Withstands so₂ concelerrations txog li 80mg / maub (GB / T 19292.3 chav kawm III)
Tus kheej -} kho cov peev xwm: Tooj -} rich rich micro - a/ey (0.255%) nquag ntxuav cov cheeb tsam oxide
2. Cov thev naus laus zis kev cia siab
Lav pom lub zog: 235mpa tsawg kawg nrog kev sib txawv zoo thoob plaws phaj dav dav dav dav
Av qeeg - tsis kam ua: 26% yam tsawg kawg nkaus elongation (tshaj li gb / t 4171 yuav tsum tau)
Fabrication - tus phooj ywg: Thov kom muaj ntau dua los yog sib npaug rau 0.42 ua kom txias dua li khoov thiab cov vuam hlau
3. Ntsuab kev ua haujlwm zoo dua
Pleev -} dawb ntev ntev: Tshem tawm VOC emissions los ntawm txheej txij nkawm
100% rov ua dua tshiab: Pom los ntawm Tuam Tshoj daim ntawv pov thawj hauv tsev ntsuab
