ASTM A242 yog cov hlau tsis tshua muaj zog thiab yog ib qho ntawm cov huab cua huab cua siv hauv Tebchaws Meskas rau atmospheric corrosion kuj.
ASTM A242 / A242M tus qauv siv rau lub zog siab qis-alloy qauv steel duab, daim hlau, thiab tuav tau npaj rau welded, riveted, lossis bolted siv. Cov hlau no feem ntau yog siv rau hauv cov ntawv thov uas txo qhov hnyav lossis ncua kev pabcuam lub neej tseem ceeb. Lawv atmospheric corrosion kuj yog qhov zoo dua li cov pa roj carbon monoxide steels nrog lossis tsis muaj tooj liab. Thaum tag nrho raug rau huab cua, cov hlau no tuaj yeem siv rau hauv qhov liab qab (tsis muaj xim) rau ntau daim ntawv thov. Cov qauv no tsuas yog siv tau rau cov khoom siv nrog lub thickness tsawg dua lossis sib npaug li 4 ntiv tes [100mm].
