ASTM A500 yeeb nkab yog cov yeeb nkab tiv thaiv corrosion rau kev tsim kho, ua los ntawm seamless txias-formed carbon steel yeeb nkab. Cov yeeb nkab qib no muaj nyob rau hauv round, square, thiab rectangular yeeb nkab hom thiab yog dav siv nyob rau hauv ntau yam kev tsim kho thiab engineering daim ntaub ntawv.
ASTM A500 cov kav dej muaj nyob rau hauv txoj kab uas hla ntawm 1/4 nti mus rau 24 ntiv tes, nrog phab ntsa tuab ntawm 3 hli mus rau 12 hli, nyob ntawm txoj kab uas hla ntawm cov yeeb nkab.
ASTM A500 cov pa roj carbon steel kav muaj qhov ua siab ntev, thiab ASTM A500 steel kav txuag nqi vim lawv lub zog siab-rau-hnyav piv. Thiab ASTM A500 cov kav dej square yog qhov zoo nkauj thiab muaj qhov zoo tshaj plaws weldability.
