Q235 (GB / T 700) yog Tuam Tshoj feem ntau tsim nyog muaj peev xwm ua rau hlau, nrog cov khoom siv tshuab ua kom haum rau kev tsim cov tshuab:
Paib lub zog:Loj dua los yog sib luag rau 235 MPa (rau thickness tsawg dua los yog sib npaug ntawm kev ruaj khov zoo li cov thav duab lossis scaffolding.
Lub zog tensile:375-500 MPA, muab kev sib luag txaus rau khoov thiab sib sau yam tsis muaj fracturing.
Elongation:Ntau dua los yog sib npaug rau 26% (rau cov ntawv nyias nyias), cia nws ncab thaum lub ntiaj teb lossis kev cuam tshuam} tseem ceeb rau kev tsim kho.
Kev Cuam Tshuam Cov:Loj dua los yog sib luag rau 27 J ntawm 20℃(tsis tau teev tseg rau qhov kub tsawg, txwv siv hauv huab cua txias.
Cov khoom lag luam no ua Q235 zoo tagnrho rau tsis {{1} Tus cwj pwm tseem ceeb tshaj plaws Nws ua kom haum nrog ASTM A36 (USA) thiab EN6}}}}} 2 s235jr muaj stricter- 20℃tej yam yuav tsum tau ua. On ua {13- hauv Suav teb, Q235 yog nquag muaj li "Q235 kub-rolled round bar rau kev tsim kho 50 lab tons.
