Cov Khoom Siv
A572 cov qib kev qhia muaj lub zog zoo, kev ua tau zoo, thiab weldability, ua rau lawv tsim nyog rau cov cuab yeej siv hauv cov choj, vaj tse, siv cov cuab yeej siv.
Cov menyuam kawm qib
Ntau qib kawm hauv A572 cov lus qhia (piv txwv li, A572 Qib 50, A572 Qib 50) muaj qib sib zog thiab lwm yam yuav tsum tau ua daim ntawv thov tshwj xeeb.
A588 hlau
Muaj pes tsawg
A588: ASTM A588 yog qhov siab- lub zog, qis} alieco alirocceral steel nrog ntxiv atmospheric corrosion. Nws feem ntau muaj cov ntsiab xws li tooj liab, chromium, npib tsib xee, thiab phosphorus.
Cov Khoom Siv
A588 tsim qauv rau sab nraum zoov chaw thiab cov qauv txheej txheem raug rau cov huab cua phem. Nws tsim cov txheej txheem tiv thaiv ntawm xeb thaum raug rau cov huab cua, muab cov tshuaj corrosion tsis tas yuav xav tau kev pleev xim.
Cov Ntawv Thov
A588 steel feem ntau yog siv nyob rau hauv archage nta, txuas hniav, kis cov yees, thiab lwm yam kev thov freight, thiab lwm yam kev siv cov txheej txheem ua kom tau zoo.
Qho sib txawv
Corrosion Kuj
A572 tsis muaj tib theem ntawm corrosion tsis kam raws li sau ntawv A588 vim muaj cov ntsiab lus ntxiv hauv A588 uas muaj cov atmospheric corrosion tsis kam.
Siv
A572 feem ntau yog siv rau cov ntawv thov qauv uas xav tau lub zog muaj zog, thaum A588 tshwj xeeb yog tsim rau cov qauv sab nraum zoov kom haum rau atmospheric corrosion.
Huab Cua Cov Khoom Siv
A588 txhim kho lub sijhawm tiv thaiv kev tiv thaiv lub sijhawm thaum raug rau ib puag ncig, txhim kho nws txoj kev tiv thaiv rau cov atmospheric corrosion.
Thaum xaiv nruab nrab ntawm A572 thiab A588, xav txog qhov tseem ceeb xws li lub phiaj xwm qhov chaw, thiab cov khoom siv xav tau rau cov khoom siv uas tsim nyog rau kev thov ntawm tes.

Cov FAQ
Q: Dab tsi yog A572 qib steel?
A: A572 Qib 42, 50, 55, 60, 65 Cov Phiaj Hlau Steel {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}
ASTM A572 Steel phaj yog cov qib nrov ntawm high- muaj zog {}} alloy (hsla) steel uas feem ntau yog siv rau cov ntawv thov txheej txheem. A572 steel muaj cov tshuaj alloys uas ua rau cov khoom siv tawv tawv thiab muaj peev xwm ua rau cov qib steel nrog cov ntawv sib xyaw zoo sib xws.
Q: Puas yog A572 tib yam li 50W?
A: 44W / 50W / 50WT yog cov khoom lag luam me me hauv qab canadian engentification csa cov qhab nia tshwj xeeb 300W / 350WT. HS 50W qeb kuj tseem yuav suav ua AQUEM A572-50 (txog li 4 "), nrog tsawg kawg lub zog ntawm 50ksi.
Q: yog A572 steel corrosion resistant?
A: Los tsim A572 cov hlau, hlau ua ke nrog cov roj carbon, mangles, phosphorus, sulfur, thiab silicon. Cov hlau ua kom muaj zog dua, ua kom nruj dua, thiab ntau dua corrosion - tiv taus tom qab ntxiv ntawm cov khoom sib xyaw.
Q: Dab tsi yog A588 hlau sib npaug rau?
A: Corten ib lub phaj steel
Los ntawm cov tshuaj lom neeg muaj pes tsawg leeg ASTM A242 muaj qis dua cov pa roj carbon, thiab A588 qib ib lub phaj yog sib npaug rau Corten ib lub phaj steel.
Q: Dab tsi yog ASTM A588 cov khoom siv?
A: A588 yog hom huab cua ua huab cua uas muaj npe rau nws cov kev zam tshwj xeeb corrosion. Nrog nws lub peev xwm tshwj xeeb los ua ib qho kev tiv thaiv xeb {2} Zoo li saum npoo, nws tshem tawm qhov xav tau ntawm cov hmoov ntau ntxiv, txo tus nqi kho. ASTM A588 kuj tseem hu ua Corten® thiab npog cov qauv qauv, phaj, thiab bar.
Q: Qhov sib txawv ntawm A572 thiab A588 li cas?
A: A588 txhim kho ib txheej xeb tiv thaiv (patina) thaum nthuav tawm rau cov khoom siv sab nraum zoov sab nraum zoov sab nraum zoov sab nraum zoov lossis lwm yam kev tiv thaiv kev tiv thaiv lossis lwm cov chaw tiv thaiv zoo sib xws.
Q: Dab tsi yog qhov txawv ntawm A36 thiab A588?
A: Tshuaj lom neeg muaj pes tsawg leeg: A36 yog cov pa roj carbon hlau uas feem ntau muaj txog 0.29% cov hlau, thaum Aloy- allloing cov ntsiab xws li tooj liab, chromium, thiab npib tsib xee. Qhov tseeb chemical muaj cov tshuaj yuav sib txawv raws li cov khoom lag luam tshwj xeeb.
