Astm hais txog Asgkas Society rau kev sim thiab cov qauv ntaub ntawv.
{-653 yog ib qho ntawm nws tus lej ceg txheem.
ASTM A653 yog tus qauv specification rau kub-dipped galvanized hlau alloy los yog galvanized steel los xij.
ASTM A653 G90 yog hais txog ASTM A653 specification, galvanized txheej code G90 sawv cev rau lub ntsiab lus hais tias cov sum ntawm ob-sided zinc txheej yog 0.9 oz / ft2 (qhov nruab nrab yam tsawg kawg nkaus tus nqi ntawm peb cov ntsiab lus ntawm ob sab) lossis 0.8 oz / ft2 (qhov tsawg tshaj plaws ib qho taw tes ntawm ob sab) tus nqi).
ASTM A653 G90 hais txog galvanized steel ntawv, cov khoom siv yog G90 (raws li ATM A653 txuj ci), tuab 3.2 hli.
Cov txheej txheem Asmeskas yog tshwj xeeb. Muaj ob chav ntsuas qhov hnyav (g / m2) xws li Z90 thiab British qhov hnyav (oz / ft2) xws li G90. Qhov hnyav sib txawv ntawm ob yog li 3 zaug.
ASTM A653 Qhov Zoo
Nyias-coated kub-dip galvanized cov ntaub ntawv muaj peev xwm vuam zoo heev thiab kev ua haujlwm. Nws tuaj yeem siv los ntawm kev siv dav dav mus rau kev kos duab sib sib zog nqus thiab tuaj yeem xaiv raws li lub hom phiaj.
Thick galvanized kub-dip galvanized cov ntaub ntawv muaj corrosion kuj zoo heev. Ntau daim ntawv thov tuaj yeem siv los ntawm kev xaiv spangles thiab tom qab ua haujlwm.
Hoto DIP Alloy Steel tsis tsuas yog tau zoo heev corrosion tsis kam tab sis kuj muaj advesion zoo thiab duction ntawm txheej, yog li nws tuaj yeem ua tau zoo ua kev ua tau zoo. Qhov zoo dua yog tias nws muaj cov tsos zoo nkauj thiab tuaj yeem siv rau cov ntawv thov uas lub sab saum npoo tsis pleev xim.
ASTM A653 Sib npaug
ASTMA653 yog tus qauv Asmeskas, uas yog sib npaug ntawm Japanese Jis g 33}}}}}}}}}}}}} }ating້ນ steelness ntawm 0.3 oz / square nti. Cov khoom muaj cov kev qhia dav dav.
ASTM A653 Kev Sib Tw
Cov khoom muaj nyob rau hauv ntau lub npe raws li hauv qab no:
Kev lag luam hlau (CS Hom A, B, thiab C),
Sib sau hlau (FS hom A thiab B),
Daim duab sib sib zog nqus hlau (DDS),
Ntxiv sib sib zog nqus nqus hlau (EDDS),
Steel qauv (SS),
Siab lub zog txo alloy steel (hslas ntaus a), thiab
Lub zog siab tsis tshua muaj hlau hlau (HSLAS Hom B).
