Cov Khoom Siv
Q355gnh Kub Cov Hlau RolledFeem ntau siv rau kev siv hauv tsheb, ntim, vaj tse, txuas hniav, thiab lwm yam txheej txheem. Cov phiaj xwm muaj cov atgor atmosphion corrosphion kev tiv thaiv piv rau weldayrable huab cua hluav taws xob steel Q355NH.
Nrog rau cov txiaj ntsig lub zog ntawm tsis muaj tsawg dua 355 MPa thiab lub zog tensile xws li ntawm 470 MPa kub cov phiaj, muab cov nqi ntev thiab txo cov nqi txij nkawm.
Cov khoom siv alloy xws li tooj liab (Cu), npib tsib), thiab chromium (acidic), acidic lossis alkaline atmospheres, thiab cov av noo siab.
This makes Q355GNH plates highly suitable for marine applications, chemical plants, and bridge construction, where long-term exposure to the elements is common.
Hauv kev sib piv rau Q355Nh, q355nnhnh pom tau qib siab ntawm kev tiv thaiv kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob twj siab thiab kev ua haujlwm hnyav thiab ua haujlwm nrog cov hlau no.
