Ipleyiti yentsimbi ye-Q355C

Q355 Inkcazo yentsimbi
I-Q355 luhlobo lwentsimbi. Luhlobo lwentsimbi ephantsi ye-alloy ephezulu, esetyenziswa ngokubanzi kwiiBridges, izithuthi, iinqanawa, ukwakhiwa, iinqanawa zoxinzelelo, izixhobo ezikhethekileyo, njl., apho "Q" ithetha amandla okuvelisa, i-355 ithetha amandla emveliso yale ntsimbi yi-355MPa. , kwaye ixabiso lesivuno liya kuncipha ngokunyuka kobunzima bezinto eziphathekayo.

Ukwenziwa kweekhemikhali:
C: 0.24, Si: 0.55, Mn: 1.60, P: S: 0.035, 0.035, Cr: 0.30, Ni: 0.30, Cu: 0.40

C	Si	Mnu	P	S	Cr	Ni	Cu
0.24	0.55	1.60	0.035	0.035	0.30	0.30	0.40

Intsimbi ye-Q355 yintsimbi ephantsi ye-alloy yaseTshayina ephezulu, ethathe indawo ye-Q345, ukuxinana kwezinto yi-7.85 g/cm3. Ngokutsho kwe-GB/T 1591 -2018, i-Q355 inamanqanaba ama-3 omgangatho: Q355B, Q355C kunye ne-Q355D. "Q" yileta yokuqala ye-Chinese Pinyin: "qu fu dian", oku kuthetha ukuba Amandla oMvuno, "i-355" lixabiso elincinci lamandla okuvelisa i-355 MPa yobunzima bensimbi ≤16mm, kunye namandla e-tensile yi-470-630 Mpa.

Iimpawu kunye nezicelo

Intsimbi ye-Q355 ineempawu ezilungileyo zoomatshini, i-weldability entle, iipropathi zokusetyenzwa ezishushu nezibandayo kunye nokumelana nomhlwa. Ingasetyenziselwa ukwenza iinqanawa, iibhoyila, iinqanawa zoxinzelelo, iitanki zokugcina i-petroleum, iibhulorho, izixhobo zesikhululo samandla, ukuphakamisa oomatshini bokuthutha kunye nezinye iindawo eziphezulu ezidityanisiweyo zesakhiwo.
