ASTM A588 hlauyog hom huab cua ua huab cua uas muaj npe rau nws cov kev zam corrosion tsis kam. Nrog nws lub peev xwm tshwj xeeb los ua ib qho kev tiv thaiv xeb {{1} Zoo li nto, nws tshem tawm qhov xav tau rau cov txheej txheem ntxiv, txo tus nqi kho.
ASTM A588 muaj 50ksi yam tsawg kawg nkaus cov txiaj ntsig lub zog thiab lub zog 70 yam tsawg kawg nkaus. Weathering hlau yog tsis haum rau siv nyob rau hauv tseem ceeb thauj {}} Cov tswv cuab cov kabmob saum toj no 450 degrees Celsius.
Cov yam ntxwv tseem ceeb thiab cov txiaj ntsig
Tshwj kev txiav txim siab corrosion:Qhov sib ntxiv ntawm tooj thiab lwm yam alloying txhim kho cov hlau muaj peev xwm ua ib txheej xeb tiv thaiv thaum muaj ib puag ncig ntuj.
Qhov kev ua yeeb yaj kiab oxide zoo li no ua raws li txoj kev thaiv oxide oxide ua raws li kev thaiv, zoo tiv thaiv kev xeb ntxiv yam tsis tas yuav tsum muaj tsho tiv thaiv ntxiv ntxiv.
Thiaj li, cov qauv sib xyaw los ntawm ASTM A588 nthuav tawm corroscer tsis kam nyob rau hauv huab cua atmospheric, tswjfab kom muaj kev ruaj khov txawm nyob hauv ib puag ncig hnyav.
Cov tshuab Aperospheric tsis kam ntawm Astm A588 Steel tseem ceeb heev outslbon steels zoo li A36 thiab A572}}}}}}}}}}}}}}}}}}}}}}}}}}}}}
Thaum tsim tau zoo thiab raug rau cov cua nab kuab, A588 siv tau rau ntau cov ntawv thov hauv nthuav tawm (tsis lees paub).
Siab lub zog thiab durability:ASTM A588 steel muaj lub zog siab tensile lub zog, ua rau nws tiv thaiv cov nra hnyav thiab kev ntxhov siab hnyav.
Nws qhov tshwj xeeb nyuaj thiab kev cuam tshuam tsis haum rau cov qauv tsim kom raug rau cov zog uas muaj zog, xws li txuas hniav, thiab cov cuab yeej siv khoom.
Nrog rau kev tu xyuas kom zoo, astm A588 cov qauv steel tuaj yeem ua tiav ntev- lub neej pab cuam.
Kev thov kom zoo nkauj kom zoo nkauj:Tshaj dhau nws cov kev ua tau zoo, astm A588 hlau tsim cov huab cua zoo nkauj uas muaj qhov sib txawv.
Nws lub xeb - xim nto nta sov tones sov thiab kev ntxhib los mos, ntxiv qhov tob thiab cov kws tsim khoom tsim architectural.
Qhov kev zoo nkauj no ua rau nws dav siv hauv kev kos duab, duab puab sab sab sab nraud, thiab ntau yam khoom zoo nkauj.

Cov Ntawv Thov
Txuas hniav:ASTM A588 steel yog qhov kev xaiv nrov rau kev tsim kho choj vim nws lub zog siab, corrosion tsis kam, thiab tus nqi- ua hauj lwm ua tau zoo. Txuas hniav raug rau Saltwater, cov ntug hiav txwv muaj txiaj ntsig zoo los ntawm cov kev xav tau tshwj xeeb tau txais txiaj ntsig thiab ua kom muaj kev txij nkawm ntev.
Vaj tse thiab facades:Los ntawm skyscrapers rau cov qauv nyob, Astm A588 pom daim ntawv thov hauv cov vaj tse, cov phab ntsa kab hlau, thiab cov vov tsev.
Nws cov tsos tshwj xeeb ntxiv ib qho kev tsim qauv ntawm kev tsim qauv thiab paub qhov txawv ntawm cov haujlwm tsim duab kos duab, thaum nws cov kev tiv thaiv kev muaj zog muab tiv thaiv huab cua thiab kev tiv thaiv kev xeb.
Cov qauv sab nraum zoov:ASTM A588 yog nquag siv nyob rau hauv cov qauv sab nraum zoov zoo li chaw ntau pob, Pavilions, thiab qhib- huab cua ua pa. Cov qauv no yuav tsum muaj cov ntaub ntawv uas tuaj yeem tiv thaiv tau kom sib txawv ntawm huab cua uas tsis muaj kev nyab xeeb lossis ua kom zoo nkauj.
ASTM A588 lub peev xwm los mus thev hnyav ib puag ncig ua rau nws xaiv qhov zoo tshaj plaws rau cov phiaj xwm zoo li no.
Cov Khoom Siv Siv:Cov tshuab siv hnyav thiab cov khoom siv siv tau feem ntau yog qhov xav tau, suav nrog cov tshuaj uas xeb thiab huab cua huab.
ASTM A588'C corrosion tsis kam thiab siab zog ua nws cov khoom siv txhim khu kev qha xws li cov thoob, hluav taws xob caj npab, thiab chassis, kom ntseeg tau cov khoom siv ntev thiab ua tau zoo.
