ASTM A588 Qib K Hlau phajYog lub siab - lub zog, qis {{{{{}} almoy qauv hlau tsim rau atmospheric corrosion.
Nws muaj qhov tsawg kawg los lub zog muaj zog ntawm 345 MPa rau daim hlau thickness, ua rau nws zoo tagnrho rau cov kev siv thiab lub zog.
Thaum pom cov huab cua kom zoo, A588 qib k tsim cov yeeb yaj kiab oxide, uas minimization ntxiv kev txhim kho corrosion thiab tshem tawm cov kev xav tau pleev xim.
Qhov no ua rau nws haum rau choj, cov qauv txheej txheem txheej txheem, thiab sab nraum zoov kos duab kos duab siv hauv cov khoom mos.
Qhov ntau thiab tsawg
Thickness: 6 hli - 200 hli
Dav: 1500 hli - 4050 hli
Ntev: 3000 mm - 15000 mm

Cov ntsiab lus tseem ceeb
Cov Atmospheric Zoo Tshaj Plaws Dillionance: Kev pabcuam lub neej mus txog 50 xyoo yam tsis muaj kev pleev xim nyob rau hauv ib puag ncig sab nraum zoov.
Tus nqi efficiency: txo cov nqi txij nkawm los ntawm 30-40% dhau cov pa roj carbon hlau vim nws tus kheej- tiv thaiv patina.
Superior zog - rau {{1} Txoj cai hnyav} qhov hnyav hnyav uas tsis muaj lub zog sib cuam tshuam.
Kev Lom Zem: Kev Txij Nkawm Me thiab ntev ua rau nws zoo tagnrho rau eco -}} paub txoj haujlwm.
