Q355NE low-alloy (HSLA) hlau
Q355NE hsla steel belongs rau hauv qab lub thawv kub siab-lub zog steel phaj. Kev siv tus qauv ntawm Q355NE low alloy steel yog cov txheej txheem tshwj xeeb ntawm GB / T1519-2018.
Q355NE siab zog tsis tshua muaj hlau hlau muaj cov khoom siv zoo, tsis muaj qhov kub thiab txias, plasticity thiab weldability. Nws tuaj yeem siv los ua cov hlab ntsha nruab nrab thiab tsis tshua muaj siab, cov roj tso tsheb hlau luam, tsheb, cranes, mining machinery, fais fab chaw nres tsheb, txuas hniav thiab lwm yam qauv, cov khoom siv kho tshuab thiab cov qauv tsim uas dais dynamic loads. Nws tuaj yeem siv los ua cov khoom siv hlau dav dav hauv cov khoom kub-dov los yog normalized.
Q355NE siab zog uas tsis muaj alloy yuav siv tau nyob rau hauv ntau yam qauv nyob rau hauv txias cheeb tsam saum toj no -40 degree . Q355NE siab zog qis alloy hsla steel yog dav siv hauv engineering, mining machinery, txuas hniav, tsheb, nkoj, tsev, siab hlab ntsha, khoom tshwj xeeb, thiab lwm yam.
