Ib nroos: Cov Tub Ntxhais Sib Txawv
Corten A (ASTM A242):Optimized rauatmospheric corrosionCov. Nws tau siab dua phosphorus (p) thiab tooj (CU) cov ntsiab lus.
Corten B (ASTM A588):Balanced rau ob qho tib siSiab Zogthiabatmospheric corrosionCov. Nws muaj ntau dua cov pa roj carbon (c) thiab ntxiv chromium (CR) thiab npib tsib leeg (NI) rau kev siv cov tawv tawv thiab tawv me me.
Xav txog nws li no:Corten a yog rau cladding thiab architecture,thaumCorten B yog rau cov qauv thiab txuas hniav.

Qhov sib txawv tseem ceeb piav qhia
1. Tshuaj lom neeg sib xyaw & nws cov kev cuam tshuam
Corten asiab duaPhosphorus (p)Tseem txhim kho nws cov atmospheric corrosion tsis kam, tso cai rau cov kev tiv thaiv patina los ua kom muaj txiaj ntsig zoo dua. Txawm li cas los xij, High P tuaj yeem ua rau cov hlau ntau dua nkig thiab nyuaj rau weld hauv cov phiaj tuab.
Corten Bmuaj cov ntsiab lus nyob qis dua tab sis ntxivChromium (cr)thiabNpib tsib caug (ni)Cov. Qhov kev sib xyaw no muab cov khoom siv corrosion zoo thaum ua kom muaj zog, tawv, thiab yooj yim weldable txawm nyob rau ntu tuab tuab heev. Nws cov kev ua ntsuas yog tswj tau nruj rau cov txheej txheem kev ua haujlwm.
2. Cov Khoom Siv Kho Tshuab & Cov Thickness
Qhov no yog qhov tseem ceeb tshaj plaws ua rau muaj ntau:
Corten ayog feem ntau acorrosion - tsis kamcov khoom siv. Nws cov cuab yeej siv tshuab (zoo li paib muaj zog) tsuas yog lav los ntawm tus qauv ua kom tuab ntawm12,5 hli (0.5 nti)Cov. Tshaj li ntawd, nws yuav tsis tau raws li qhov muaj zog yam tsawg kawg nkaus uas yuav tsum tau ua rau cov qauv kev suav.
Corten Byog aTxheej txheem steelCov. Lub ASTM A588 tus qauv lees paub nws cov khoom siv kho tshuab (min {{}} mpa yield zog) rau thicknessesTxog li 200 hli (8 ntiv)Cov. Qhov no ua rau nws xaiv tsuas yog kev xaiv rau thauj khoom - cov kabmob sib txuas.
3. Daim ntawv thov -}} kev xaiv tsav
XaivCorten aThaum daim ntawv thov yogTsis - cov qauv lossis siv cov ntawv nyias nyias / daim hlauThiab qhov kev xav tau tseem ceeb yog lub aesthetic, tus kheej - tiv thaiv xeb tas. Piv txwv: lub tsev tawv nqaij, cov ntxaij zoo nkauj, vaj zaub, duab puab kos duab.
XaivCorten BThaum daim ntawv thov yogyam xwm txheejThiab xav tau ob qho huab cua zoo nkauj thiab lav tau muaj zog. Piv txwv: Choj girders, kab qauv qauv, ru tsev trusses, thiab cov khoom vaj tsev loj uas yog ib feem ntawm lub tsev thauj khoom no.
