Q890D yog quenched thiab tempered steel phaj rau cov qauv muaj zog. Qhov "Q" hauv qib txhais tau tias tawm los, "890" yog tus nqi tawm los, thiab "D" txhais tau tias qib. Nws sib raug rau lwm qib: WQ890D, S890Q.
Q890D steel phaj siv tus qauv: GB / T 16270-2009.
Q890D steel phaj xa raws li txoj cai (kev kho cua sov): quenching thiab tempering (quenching thiab tempering)
Q890D quenched thiab tempered high-strength steel yog tsim rau kev tsim steel qauv xws li thee mine hydraulic kev txhawb nqa, tsheb hnyav, thiab engineering machinery uas yuav tsum tau vuam zoo. Piv txwv li, drilling rigs, hluav taws xob shovels, hluav taws xob log tsheb thauj khoom, tsheb mining, excavators, loaders, bulldozers, ntau yam cranes, thee mine hydraulic txhawb thiab lwm yam khoom siv tshuab thiab lwm yam khoom siv hauv mining thiab ntau yam engineering siv quenched thiab tempered siab. - lub zog steel. Tsawg carbon sib npaug tsim qauv, nrog kev ua haujlwm zoo vuam; txhaj tshuaj blasting kev kho mob ua ntej quenching ntawm steel phaj, radiant raj cua sov ntawm quenching rauv, uas tsis yog-oxidation cua tswj thiab lwm yam kev ntsuas, kom cov hlau phaj muaj zoo nto zoo; tshwj xeeb cov menyuam tsim ntawm quenching tshuab, zoned dej txias thiab lwm yam., qhov zoo-guaranteed steel phaj muaj cov yam ntxwv txhua yam khoom thiab zoo phaj zoo.
