ASTM A871 yog ib qho American standard weathering steel phaj.
ASTM A871 yog npaj rau cov qauv tubular thiab cov khoom txhawb nqa lossis lwm yam kev siv tsim nyog. Nws yog lub zog siab, qis-alloy steel phaj uas tau muab faib ua ob qib, Gr60 thiab Gr65, kom ua tau raws li cov txheej txheem tsim khoom siv.
Nws tuaj yeem xa tuaj rau hauv qhov kub-dov, normalized, lossis quenched thiab tempered mob.
