A588 yog hom huab cua huab cua uas muaj npe nrov rau nws qhov tshwj xeeb corrosion kuj. Nrog nws lub peev xwm tshwj xeeb los tsim kev tiv thaiv xeb -zoo li nto, nws tshem tawm qhov xav tau ntawm cov txheej txheem ntxiv, txo cov nqi kho.
ASTM A588 tseem hu ua Corten thiab npog cov qauv duab, phaj, thiab bar. Cov hlau no yog tsim los ntawm tooj liab, chromium, npib tsib xee, thiab lwm yam khoom uas muab nws cov huab cua tsis kam. Nws kuj tseem paub txog nws lub zog siab, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim vaj tsev thiab cov qauv siv nrog rau cov txuas hniav, cov tsev, thiab cov qauv sab nraum zoov.

ASTM A588 specification tshwj xeeb yog tsim los muab siab atmospheric corrosion kuj, ua rau nws haum rau sab nraum zoov daim ntaub ntawv uas raug rau lub ntsiab yog ib qho kev txhawj xeeb.
Ib qho ntawm cov yam ntxwv tshwj xeeb ntawm ASTM A588 steel yog nws lub peev xwm los tsim kev tiv thaiv xeb -zoo li nto thaum raug rau huab cua. Cov txheej txheem oxidation ntuj no tsim ib qho kev thaiv uas inhibits corrosion ntxiv, yog li tshem tawm qhov xav tau rau cov txheej txheem tiv thaiv ntxiv. Cov huab cua zoo li ASTM A588 steel feem ntau suav hais tias yog qhov zoo nkauj thiab nquag siv hauv kev siv vaj tsev.
ASTM A588 muaj 50ksi yam tsawg kawg nkaus yield zog thiab 70ksi yam tsawg tensile zog. Weathering steels tsis haum rau kev siv hauv kev thauj khoom tseem ceeb-cov tswv cuab ntawm qhov kub siab tshaj 450 degrees Celsius.
Zuag qhia tag nrho, ASTM A588 yog dav siv nyob rau hauv kev tsim kho kev lag luam vim nws zoo heev corrosion kuj, siab zog, thiab check xwm, ua rau nws haum rau ntau yam ntawm cov qauv siv raug rau hnyav ib puag ncig tej yam kev mob.
