ASTM A449 Cov Khoom Siv Hluav Taws Xob
ASTM A449 npog taub hau bolts, pas nrig, thiab thauj tog rau nkoj bolts nyob rau hauv txoj kab uas hla ntawm 1/4 "mus rau 3" suav nrog. Nws yog nruab nrab lub zog ntsia liaj qhov rooj tsim los ntawm cov pa roj carbon nruab nrab lossis hlau alloy uas txhim kho nws cov txiaj ntsig kev siv tshuab los ntawm kev kho cua sov. Nws yog npaj rau kev siv engineering dav dav.
ASTM A449 zoo ib yam hauv chemistry thiab lub zog rau ASTM A325 thiab SAE J429 qib 5. Txawm li cas los xij, A449 hloov pauv ntau dua hauv qhov kev txiav txim siab tias nws npog ntau txoj kab uas hla loj dua thiab tsis txwv los ntawm ib qho kev teeb tsa tshwj xeeb.
