A1085 Hollow Structural Section HSS
ASTM A1085 - Cov Khoom Siv Tau Zoo:
ASTM A1085 muab kev txhim kho kev ua tau zoo los tsim kev tsim nrog HSS yooj yim dua thiab ua haujlwm zoo dua rau cov qauv tsim qauv. Qee qhov txiaj ntsig ntawm qhov kev qhia tshiab muaj xws li:
Tighter Tolerances - ASTM A1085txiav qhov tso cai rau phab ntsa ntawm A500 nyob rau hauv ib nrab thaum tseem ntxiv ib tug loj kam rau ua. Qhov tshwm sim yog ib ntu uas tso cai rau cov neeg siv tshwj xeeb siv cov phab ntsa nominal tag nrho rau cov khoom seem thiab kev sib txuas tsim los txhawb nqa ntau lub peev xwm.
Yield Stresses - ASTM A1085qhia ib qho kev ntxhov siab tsawg kawg nkaus ntawm 50 ksi rau tag nrho cov duab thiab caps qhov kev ntxhov siab ntawm 50 ksi. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv seismic uas vam khom lub peev xwm tsim.
Toughness yuav tsum tau - ASTM A1085yuav tsum muaj tus qauv Charpy V-notch test uas ua rau 25 ft-lb ntawm 40 degrees F ua cov khoom siv no haum rau AASHTO Zone 2 pob txha tseem ceeb lossis lwm yam kev siv uas yuav tsum muaj qhov hnyav.
