** 1. Vim li cas nws hu ua A36? **
Lub npe "A36" los ntawm ASTM International txheem uas txhais tau nws cov khoom. Qhov "" tsim nws raws li ferrous (hlau-} raws cov qauv carbon cov qauv hlau. Qhov "36" yog hais txog nws li tsawg zog lub zog ntawm 36,000 phaus ib square nti (PSI). Yog li, lub npe ncaj qha qhia txog nws cov khoom sib cais thiab cov khoom siv kho tshuab.
** 2. A36 hlau xeb? **
Yog lawm, A36 steel yog qhov ua rau xeb muaj txiaj ntsig (corrosion) vim tias tsis muaj cov roj ntsha uas tsis muaj cov roj chev, uas yog ntxiv rau txheej tiv thaiv. Thaum raug rau ya raws thiab oxygen, A36 hlau yuav tsim cov hlau oxide, feem ntau yog hu ua cov xeb. Nws yuav tsum muaj kev tiv thaiv kev tiv thaiv zoo li cov xim pleev xim lossis galvanization kom tiv thaiv corrosion.
** 3. Dab tsi yog muaj zog tshaj A36? **
Ntau cov hlau muaj zog tshaj A36. Cov qauv piv txwv suav nrog:
* ** High {- Lub zog qis -}}} Alloy ali72 Qib 50, uas muaj tsawg kawg nkaus lub zog ntawm 50,000 PSI.
* ** Quenched thiab Tempered (Q & T) alloy steels ** Zoo li ANTM A514, uas tuaj yeem muaj cov txiaj ntsig zoo tshaj 100,000 psi thiab siv nyob rau hauv cov ntawv thov xav tau xws li crane booms.
* ** Kev ua phem rau - Tsis kam (AR) steels ** zoo li AR400 lossis AR500, uas yog qhov tawv me me rau huab coj kev tiv taus.
* ** Stainless hlau ** Hauv 400 Series (piv txwv li, 410, 440) kuj tuaj yeem muaj zog dua A36.
** 4. Puas yog A36 zoo rau vuam? **
Yog lawm, A36 hlau feem ntau suav tias yog cov zoo rau vuam. Nws muaj cov ntsiab lus carbon tsawg, uas yog thawj qhov kev txiav txim siab ib tus hlau lub weldability. Cov ntsiab lus ntawm cov roj carbon tsawg tsawg kev pheej hmoo ntawm kev tawg hauv tshav kub {}}} cuam tshuam thaj chaw (thaj chaw ib ncig ntawm Weld). Qhov no ua rau A36 ib cov khoom siv zam txim heev thiab cov txheej txheem kev tsim kho uas siv cov txheej txheem vuam thiab cov chaw tsim khoom), thiab fcaw (flux- tus tub ntxhais).
** 5. A36 yog galvanized? **
Yog lawm, A36 yog ib qho ntawm feem ntau cov hlau ua kub - dip galvanized. Cov txheej txheem galvanizing cuam tshuam nrog kev tu cov hlau thiab tom qab ntawd hle nws mus rau hauv da dej ntawm Molten Zinc. Lub zinc txheej muab lub zog ua kom ruaj khov, ntev {{{}}} kav barrier tiv thaiv corrosion. A36 cov tshuaj muaj pes tsawg leeg, tshwj xeeb yog nws cov ntsiab lus silicon qis, ua rau nws haum rau kev tsim cov khaub ncaws hnav, cov cim nplaum galvanized txheej. Qhov no yog vim li cas koj pom A36 galvanized rau cov ntawv thov nyiam cov kab teeb style, tes ua, thiab cov neeg tiv thaiv.
