Q490DRL1 yog quenched thiab tempered high-strength steel phaj rau cov khoom siv siab, hloov qib 07MnNiVDR. Cov qib steel muaj xws li Suav pinyin sau npe "Q" sawv cev rau lub zog tawm los "yi", qhov tsawg kawg nkaus cov txiaj ntsig qis zog tus nqi 490, thiab "tsis muaj peev xwm" ntawm cov hlab ntsha qis. "" yog tsim los ntawm thawj tsab ntawv "DR" hauv Suav Pinyin thiab qhov kub thiab txias "L1".
Q490DRL1 steel phaj siv tus qauv: GB/T713.6-2023, hloov tus qauv qub GB/T19189-2011. Cov qauv no qhia txog qib kev sawv cev, xaj cov ntsiab lus, qhov loj me, qhov pom, qhov hnyav, thiab cov kev xav tau ntawm quenched thiab tempered high-strength steel daim hlau rau cov khoom siv siab. , xeem txoj kev, tshuaj xyuas cov cai, ntim, logos thiab daim ntawv pov thawj zoo.
Q490DRL1 yog qhov kub thiab txias siab lub nkoj steel phaj nrog lub zog siab, siab toughness, tsis kub toughness thiab zoo vuam kev ua tau zoo. Cov phaj hlau no tuaj yeem tswj xyuas cov khoom siv kho tshuab ruaj khov hauv qhov chaw tsis muaj qhov kub thiab txias, ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub thawv. Piv nrog rau cov tsoos uas tsis tshua muaj kub siab lub nkoj steel daim hlau, Q490DRL1 muaj zog dua thiab toughness thiab tuaj yeem tswj kev ua haujlwm ruaj khov ntawm qhov kub thiab txias. Nws tau siv dav hauv aerospace, petrochemical, tsheb tsim thiab lwm yam haujlwm.
