Dab tsi yog cov khoom ntawmSgh 440+ zHlau?
SGH 440+ h yog lub zog loj thiab cov khoom siv corrosion thiab corrosion siv hauv kev tsim kho lub tsev, kev tsim kho, kev lag luam hauv tsev thiab lwm yam kev lag luam.
SGH: steel galvanized high-zog (high-zog galvanized steel)
440: Yam tsawg kawg nkaus tensile lub zog yog 440 mpa (cov qib siab-muaj zog)
+ Z: lub galvanized txheej yog passivated (muaj zog xeb kuj zoo)
Dab tsi yog qhov sib txawv ntawm sgh 440+ Z hlau thiab dx51d?

Microalloyed Hlau |
Qee cov kev muaj zog muaj zog yuav ntxiv cov kab ntsig alloy (xws li NB, V, los txhim kho lub zog ntawm cov roj carbon monoxide) . |
SGH 440+ z galvanized steel siv nyob rau hauv lub tsheb teb?
SGH 440+ Z yog lub zog loj, nws yog qhov muaj kev nyab xeeb, nws yog ob qho kev nyab xeeb thiab kev nyab xeeb {}}
Nrog lub zog tensile ntawm ntau dua los yog sib npaug rau 440 MPa, nws tuaj yeem ua tiav kev ua kom nruj (qhov hnyav txo qis ntawm 10%), txhim kho cov tsheb ua kom hluav taws xob; Lub npoo Galvanizing + passivation muaj corrosion tsis kam ntawm cov hlau dog dig, thiab yog qhov haum rau corrosion-prone cov chaw xws li chassis .
