SM490 yog tus qauv Japanese qis-alloy lub zog loj-zog cov hlau uas siv cov kev tshwj xeeb ntawm Japanese Txuj Ci Jisg3106. Ntawm lawv, "SM" sawv cev rau tus qauv Japanese lub zog, thiab "490" sawv cev lub zog ntawm cov hlau phaj. SM490 steel phaj muaj cov yam ntxwv ntawm lub zog siab, kev tiv thaiv kev tiv thaiv, kev tawm tsam xeb, thiab kev ua haujlwm yooj yim. Nws feem ntau siv nyob rau hauv cov tuam tsev, cov choj, cov tsheb ciav hlau, roj av, ntim thiab lwm yam kev tsim kho weldability.
SM490 Cov paib hlau feem ntau yog nyob rau hauv ib txwm muaj los yog kub-rolled lub xeev thaum xa, tab sis lawv kuj tuaj yeem ua lwm lub xeev txawv raws li kev thov. Piv txwv li, SM490YA thiab SM490Y steel phiaj yog xa hauv lub xeev tsis zoo, tab sis lawv tuaj yeem ua tau zoo, tempered, thiab lwm yam raws li cov kev xav tau sib txawv. Ib qho ntxiv, SM490 Steel Steel phaj tseem muaj vuam zoo thiab ua kom nws yooj yim rau weld thiab cov txheej txheem ua haujlwm engineering.
Hauv kev tsim kho choj, SM490 hlau daim hlau tau siv dav vim lawv lub zog siab, kev tsis kam, xeb tsis kam, av qeeg thiab lwm yam khoom. Ib qho ntxiv, SM490C cov phiaj kuj tseem siv nyob rau hauv kev tsim khoom machinery xws li cov khoom siv hluav taws xob, cov khoom siv nkoj, cov khoom siv roj av thiab lwm thaj chaw.
