I-Q355C ipuleti lensimbi

Q355 Incazelo Yensimbi
I-Q355 iwuhlobo lwensimbi. Iwuhlobo lwensimbi yesakhiwo esinengxubevange ephansi, esetshenziswa kabanzi kumabhuloho, izimoto, imikhumbi, ukwakhiwa, imikhumbi yokucindezela, imishini ekhethekile, njll., lapho i-“Q” isho amandla okukhiqiza, i-355 isho amandla okukhiqiza ale nsimbi angama-355MPa. , futhi inani lokukhiqiza lizokwehla ngokunyuka kobukhulu bezinto ezibonakalayo.

Ukwakheka kwamakhemikhali:
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	UMn	P	S	Cr	Ni	Cu
0.24	0.55	1.60	0.035	0.035	0.30	0.30	0.40

I-Q355 steel insimbi yesakhiwo esinamandla e-Chinese low alloy high, ethathe indawo ye-Q345, ukuminyana kwezinto kungu-7.85 g/cm3. Ngokuya nge-GB/T 1591 -2018, i-Q355 inamazinga ekhwalithi angu-3: Q355B, Q355C ne-Q355D. I-“Q” iwuhlamvu lokuqala lwe-Chinese Pinyin: “qu fu dian”, okusho ukuthi Amandla Okukhiqiza, “355” inani elincane lamandla esivuno angu-355 MPa wogqinsi lwensimbi ≤16mm, futhi amandla aqinile angu-470-630 Mpa.

I-Datasheet nokucaciswa

Amathebula angezansi abonisa idatha yedatha ye-Q355 kanye nokucaciswa okufana nokwakheka kwamakhemikhali, kanye nezakhiwo zemishini.

Izici kanye nezicelo

Insimbi ye-Q355 inezinto ezinhle zomshini, ezishisela kahle, izici zokucubungula ezishisayo nezibandayo kanye nokumelana nokugqwala. Ingasetshenziswa ukwenza imikhumbi, ama-boilers, imikhumbi yokucindezela, amathangi okugcina uphethiloli, amabhuloho, izinto zesiteshi samandla kagesi, ukuphakamisa imishini yokuthutha nezinye izingxenye zesakhiwo ezishiselwe umthwalo ophezulu.
