ASTM A242 Hlauyog tus qauv kev qhia tshwj xeeb rau qhov siab - lub zog, qis {{{{}} alloy (hsla) qauv hlau nrog kev txhim khoatmospheric corrosion, feem ntau hu uaHuab Cua HlauCov. Nws yog feem ntau cuam tshuam nrog lub cim lag luamCor -} Kaum®(tshwj xeeb cor - kaum a).
Cov yam ntxwv tseem ceeb
- Huab Cua Hluav Taws Xob:Thaum raug rau cov huab cua kom zoo, A242 ua cov txheej txheem ruaj khov, kev tiv thaiv txheej ntawm xeb (patina) ntawm nws qhov chaw. No patina adheres khov kho rau lub hauv paus hlau thiab ua raws li txoj kev thaiv cov hlau thiab ua raws li kev thaiv, tiv thaiv kev ua xeb ntxiv, uas tshem tawm qhov xav tau ntawm ntau daim ntawv thov.
- Composition:Lub txhim kho corrosion tsis kam los ntawm cov ntsiab lus allooy, feem ntau tooj liab, chromium, thiab qee zaum nickelorus thiab phosphorus.
- Cov Khoom Siv Neeg Kho Tshuab:Nws muaj lub zog siab, nrog tsawg kawg zog zog ntawm 50 ksi (345 MPa (345 MPa (345 MPA) thiab qhov tsawg kawg nkaus tensile lub zog ntawm 70 tus mpa) rau daim hlau mus txog 0.75 ntiv tes tuab.
- Qhov ruaj khov:Nws cov atmospheric corrosion kuj yog qhov zoo dua qub (ob peb zaug uas ntawm) ntau dua li cov pob zeb dawb uas zoo li A36 lossis A572-50.
- Cov Ntawv:Nws muaj nyob rau hauv ntau cov ntawv, suav cov paib, cov ntawv, ib daim hlab, coils, tuav, thiab qauv qauv qauv.
Kev Txheeb Ze Rau Corten Hlau
Lub nkojYog thawj lub npe lag luam rau ib pawg ntawm cov huab cua hlau alloys tsim los ntawm Asmeskas hlau.
ASTM A242yog lub official istm qauv kev qhia tshwj xeeb rau ib hom ntawm cov khoom siv no, feem ntau txiav txim siab sib npaug rauCorten aHlau (thaum ASTM A588 qib A yog qhov tseem ceeb sib npaug rau corten a thiab A242 kuj tseem qee zaum cuam tshuam nrog Corten B, nyob ntawm seb daim ntawv thov / tuab).
Cov Kev Siv Cov Ntawv Siv
Vim nws lub zog siab, lub zog ruaj khov, astm A242 Weathering hlau yog dav siv nyob rau hauv sab nraum zoov, daim ntawv thov tsis tau, suav nrog:
- Txuas hniav thiab lwm yam qauv txheej txheem
- Railway Cov Vev Xaib thiab Cov Tsheb Thauj Khoom
- Cov thawv xa khoom
- Muaj huab cua piolution stacks thiab dej tso tsheb hlau luam
- Cov duab kos duab, duab puab sab nraum zoov, thiab kev tsim kho toj roob hauv pes
Tuam txhab tau
