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.
