ASTM A847 Hlau Yeeb Nkab yog cov huab cua huab cua uas yog lub zog siab, qis-alloy steel npog qhov txias-tsim welded square thiab duab plaub thiab cov yeeb nkab. Lub atmospheric corrosion tsis kam ntawm cov hlau no yog qhov zoo dua li cov pa roj carbon steel nrog lossis tsis muaj tooj liab ntxiv hauv ntau qhov chaw.
ASTM A847carbon yeeb nkab yog npaj rau welded, bolted los yog riveted kev tsim kho ntawm cov choj thiab lwm yam qauv uas muaj zog thiab txhim khu corrosion kuj yuav tsum tau. ASTM A847 muaj 50ksi yam tsawg kawg nkaus yield zog thiab 70ksi yam tsawg tensile zog.
