GB Txheem Q345D HSLA Steel
Q345D steel phaj yog hom tsis tshua muaj alloy siab - lub zog steel qauv, nws cov tshuaj muaj pes tsawg leeg muaj cov ntsiab lus me me, xws li Mn, Si, S, P, thiab lwm yam, uas tuaj yeem txhim kho lub zog thiab tawv ntawm cov hlau phaj. Lub caij no, Q345D steel phaj kuj muaj cov yas zoo thiab vuam kev ua tau zoo, uas tuaj yeem ua tiav los ntawm kev khoov, stamping, txiav, thiab lwm yam, thiab vuam zoo yog ruaj khov thiab txhim khu kev qha.
