Q420 mbale yachitsulo

Chidziwitso chachitsulo cha Q420
Q420 steel ndi kalasi yachitsulo yaku China ya Low Alloy High Structural Structural Steel, Yield Strength ndi 420 MPa, zoyezera zimayesedwa ndi zitsulo zokhala ndi mainchesi 16mm kapena mbale zachitsulo, ndipo kulimba kwake ndi 520-680 Mpa, kusalimba kwake ndi 7.85 g/ /cm3. Malinga ndi GB/T 1591-2008, Q420 ili ndi magawo 5 abwino: Q420A, Q420B, Q420C, Q420D ndi Q420E. Zofanana ndi zitsulo za Q420, kapangidwe kake ndi makina amakina, chonde onani zomwe zili pansipa.
Features ndi Ntchito
Q420 zitsulo ali ndi mphamvu zambiri, makamaka mu chikhalidwe normalized kapena normalized komanso kupsya mtima, ndi mkulu mabuku katundu makina, angagwiritsidwe ntchito zombo zazikulu, milatho, zida magetsi siteshoni, sing'anga ndi mkulu kuthamanga boilers, zombo mkulu kuthamanga, kunyamula makina, makina migodi ndi zina zazikulu welded structural mbali.
