Q275 zitsulo mbale ndi mtundu wa carbon structural zitsulo, mphamvu mkulu, plasticity wabwino ndi kudula ntchito, ntchito kuwotcherera wabwino, mbali yaing'ono akhoza kuzimitsidwa ndi kulimbikitsidwa, makamaka ntchito kupanga mbali ndi zofunika kwambiri, monga magiya ndi mitsinje. , sprockets, makiyi, mabawuti, mtedza, zitsulo gawo makina ulimi, unyolo conveyor ndi maulalo.
Q275 zitsulo mbale ofanana zinthu: lolingana Japanese JIS mtundu: SS490
International Organisation for Standardization:
E275A
Zogwirizana ndi mtundu wakale: A5
Mankhwala opangidwa (gawo lalikulu) la mbale yachitsulo ya Q275 (%)
C: ≤0.24
Mayi: ≤1.5
Kukula: ≤0.35
S: ≤0.050 (Kalasi A)
P: ≤0.045
Mbale yachitsulo ya Q275 imagwiritsidwa ntchito makamaka popanga zida zamakina zofunika kwambiri pakumanga ndi uinjiniya wa mlatho, ndipo imatha kulowa m'malo mwachitsulo cha carbon. Q215B ikufanana ndi No. 10-15. Q235B ndi yofanana ndi zitsulo 15-20, Q255B ndi zitsulo 25-30, ndipo Q275B ndi yofanana. 35-40 zitsulo.
