GB Standard Q295GNH Weathering Steel Phaj
Q295GNH steel phaj yog lub siab huab cua steel phaj, qhov kev xa khoom feem ntau yog txias dov, dov los yog tswj dov.Q295GNH weathering steel phaj yog tsuas yog siv rau txuas hniav, tsheb ciav hlau, ntim thiab nkoj nyob rau hauv ib txwm huab cua.
Q295GNH steel qib los ntawm "yield zog", "weathering" ntawm thawj tsab ntawv ntawm hanyu pinyin "Q", "GNH GNH", lub zog tawm los ntawm cov nqi qis qis thiab qib zoo (A, B, C, D, E).
Q295GNH corten steel phaj siv tus qauv: GB / T 4171-2008.
Q295GNH corten steel ntawv muaj lub zog qis thiab lub zog tensile thiab muaj nyob rau hauv ntau yam kev kho mob thiab kev sim, ua rau nws yog ib qho zoo tagnrho steel rau kev tsim kho.

Q295GNH steel phaj atmospheric corrosion kuj
High weathering steel los ntawm kev ntxiv me me ntawm alloying ntsiab xws li: Cu, P, Cr, Ni, thiab lwm yam, thiaj li hais tias nws tsim ib tug tiv thaiv txheej ntawm cov hlau matrix, thiaj li yuav txhim khu kev tiv thaiv atmospheric corrosion kev ua tau zoo ntawm steel.Q295GNH steel belongs rau high weathering steel, uas yog dav siv nyob rau hauv tsheb, txuas hniav, thiab lwm yam. Piv nrog rau cov huab cua huab cua, cov huab cua huab cua siab tau zoo dua atmospheric corrosion kuj.
