Ishidi Lensimbi le-ASTM SA283GrC/Z25 lilethwe esimweni esigoqelwe esishisayo SA283GrC Isimo sokudiliva:
Isimo sokulethwa kwe-SA283GrC: Ngokuvamile esimweni esigoqiwe esishisayo sokulethwa, isimo esithile sokulethwa kufanele sikhonjiswe kusiqinisekiso.
I-SA283GrC inani lebanga lokwakheka kwamakhemikhali: Qaphela: Ukwakheka kwamakhemikhali kwangempela kwiwaranti yefekthri yensimbi kuzosebenza.
I-Carbon C: ≤0.24 Si: (ipuleti lensimbi ≤40) ≤0.40 (ipuleti lensimbi > 40) 0.15-0.40
IManganese Mn: ≤0.90 Sulfur S: ≤0.040 Phosphorus P: ≤0.035
I-Copper Cu: 0.20 noma ngaphansi
Ipuleti lensimbi le-SA283GrC lilungele i-riveting, bolting kanye nezakhiwo zokushisela zamaBhuloho nezakhiwo.Kuyinjongo evamile yensimbi ye-carbon structural enekhwalithi yensimbi yesakhiwo.
I-SA283GrC isimo sokulethwa kwepuleti lensimbi: ukuginqika okushisayo, ukugingqika okulawulwayo, isimo esijwayelekile sokulethwa
Izinto zokwakha isithando somlilo SM400ZL ipuleti lensimbi:
I-SM400ZL ipuleti lensimbi elisezingeni eliphansi lase-Japan eline-alloy high-strength yegobolondo lokuguqulela.Leli zinga licacisa usayizi, umumo, izidingo zobuchwepheshe, izindlela zokuhlola, imithetho yokuhlola, ukupakishwa, amamaki nezitifiketi zekhwalithi zamapuleti ensimbi zesithando somlilo esiqhumayo, isiguquli namagobolondo omlilo oqhumayo.Isebenza epuleti lensimbi legobolondo lesithando somlilo elinogqinsi lwe-8mm ~ 200mm.Ukuchezuka kogqinsi olunegethivu kwepuleti lensimbi le-SM400ZL kukhawulelwe ku--0.25mm, futhi indawo yokubekezelela ukujiya izohambisana ne-GB/T709.
Ipuleti lensimbi le-S355NL [ubukhulu obuyi-8-200] bokusika, uhlu lwezinto ezibonakalayo:
Izinga eliphezulu le-S355NL: EN10025-3: Igama eligcwele: ukujwayela/ukwenza kube jwayelekile ipuleti lensimbi eligoqiwe elishisekayo.Leli zinga kanye ne-EN 10025-1 ndawonye thatha indawo ye-EN 10113-1:1993 imikhiqizo yensimbi yesakhiwo eshibilikayo egingqika eshisayo eshibilikayo, Ingxenye I: Izimo ezijwayelekile kanye ne-TS EN 10113-2:1993 imikhiqizo yensimbi yesakhiwo eshiselwe okusanhlamvu okushisayo, okugingqika okushisayo, Ingxenye II: ukujwayelekile/okujwayelekile izimo zensimbi ezigoqiwe.Lapho izinga lokushisa lebanga lingekho ngaphansi kuka-20 ° C, inani elincane lamandla omthelela acacisiwe livezwa ngo-N;lapho izinga lokushisa lingekho ngaphansi kuka - 50 ° C, inani elincane lamandla omthelela ashiwo livezwa ku-NL.
2. Incazelo ehambisanayo yezinhlamvu zebanga le-steel plate ye-S355NL:
S: insimbi yesakhiwo, N: izwe, inhloko-dolobha L: izinga lamandla omthelela amancane ashiwo lapho izinga lokushisa lingekho ngaphansi kuka - 50 ° C
I-S355ML steel plate [8-200mm obukhulu] i-thermomechanical rolling
Ipuleti lensimbi le-S355ML lilethwa kusimo sokugingqika somshini we-thermo
Izidingo Zokubumba Amakhemikhali we-S355ML
C:≤0.14,Si:≤0.5,Mn：≤1.6，P：≤0.025，S：≤0.02,Nb：≤0.05,V:≤0.1,Al:≤0.02,Ti：≤0.05,Cr:≤0,Cr:. Ni:≤0.5,Mo:≤0.1,Cu:≤0.55,N:≤0.015.
I-S355ML steel plate iyinsimbi yesakhiwo yezinhlamvu ezishisekayo egoqwe ngokushisayo, eyingxenye yochungechunge lwamapuleti ensimbi anealloy ephansi.Iwumkhiqizo ogoqekile oyisicaba onogqinsi olungekho ngaphezu kuka-120mm kanye nomkhiqizo omude onogqinsi olungekho ngaphezu kuka-150mm.U-S usho insimbi yesakhiwo, u-355 ubonisa ukuthi inani elincane lesivuno sobukhulu obufanele obungaphansi kuka-16mm ngu-355MPa, futhi u-M umele ukulethwa kwakhe, okungukuthi, ukuginqika okushisayo.Umthetho uwukuthi umthelela ekushiseni okungengaphansi kuka - 50 degrees kuboniswa ngohlamvu olukhulu L. S355 insimbi yesakhiwo esingenayo i-alloy.
Uhlelo lokusebenza lwe-S355ML steel plate
Ngaphezu kwensimbi ye-EN10,025-1, ipulani lensimbi elicaciswe ngokukhethekile kuleli zinga liphinde lisetshenziswe ezingxenyeni ezithwala umthwalo zezakhiwo ezishiselwe ezisetshenziswa ezizungeze amabhuloho, imisele, amathangi okugcina, amathangi okuphakela amanzi, njll. kanye nezinga lokushisa eliphansi.
