Ishidi Lensimbi le-ASTM SA283GrC/Z25 lilethwe lisesimweni esishisayo esigoqiwe SA283GrC Isimo sokulethwa:
Isimo sokulethwa se-SA283GrC: Ngokuvamile esimweni sokulethwa esishisayo, isimo sokulethwa esithile kufanele siboniswe ewaranti.
Inani lobubanzi bokwakheka kwamakhemikhali e-SA283GrC: Qaphela: Ukwakheka kwamakhemikhali kwangempela ewaranti yefektri yensimbi kuzosebenza.
Ikhabhoni C: ≤0.24 I-Si: (ipuleti lensimbi ≤40) ≤0.40 (ipuleti lensimbi > 40) 0.15-0.40
I-Manganese Mn: ≤0.90 I-Sulfur S: ≤0.040 I-Phosphorus P: ≤0.035
I-Copper Cu: 0.20 noma ngaphansi
Ipuleti lensimbi le-SA283GrC lifanelekela izakhiwo ze-riveting, bolting kanye ne-welding zamabhuloho nezakhiwo. Liyinsimbi yesakhiwo sekhabhoni esetshenziswa kabanzi enekhwalithi yensimbi yesakhiwo.
Isimo sokulethwa kwepuleti lensimbi le-SA283GrC: ukugoqa okushisayo, ukugoqa okulawulwayo, isimo esijwayelekile sokulethwa
Izinto zokwakha isithando somlilo se-SM400ZL ipuleti lensimbi:
I-SM400ZL iyipuleti lensimbi elijwayelekile laseJapane elinamandla aphansi elihlanganisiwe legobolondo lokuguqula. Leli zinga lichaza usayizi, ukuma, izidingo zobuchwepheshe, izindlela zokuhlola, imithetho yokuhlola, ukupakisha, amamaki kanye nezitifiketi zekhwalithi zamapuleti ensimbi egobolondo lokuqhuma, igobolondo lokuguqula kanye namagobolondo omlilo oshisayo. Isebenza epuletini lensimbi egobolondo lomlilo elinobukhulu obungu-8mm ~ 200mm. Ukuphambuka kobukhulu obungebuhle bepuleti lensimbi le-SM400ZL kukhawulelwe ku--0.25mm, futhi indawo yokubekezelela ubukhulu kufanele ihambisane ne-GB/T709.
Ipuleti lensimbi le-S355NL [ubukhulu obungu-8-200] ukwakheka kokusika, uhlu lwezinto:
Izinga eliphezulu le-S355NL: EN10025-3: igama eligcwele: ukulinganisa/ukulinganisa ipuleti lensimbi eligoqiwe elishibilikayo eligoqiwe. Leli zinga kanye ne-EN10025-1 ndawonye zithatha indawo ye-EN 10113-1:1993 imikhiqizo yensimbi eshibilikayo eshibilikayo eshibilikayo eshibilikayo Ingxenye I: Izimo ezijwayelekile kanye ne-EN 10113-2:1993 imikhiqizo yensimbi eshibilikayo eshibilikayo eshibilikayo eshibilikayo Ingxenye II: ukulinganisa/ukulinganisa izimo zensimbi eshibilikayo. Lapho izinga lokushisa lebanga lingekho ngaphansi kuka-20 ° C, inani eliphansi lamandla omthelela acacisiwe livezwa ku-N; lapho izinga lokushisa lingekho ngaphansi kuka-50 ° C, inani eliphansi lamandla omthelela acacisiwe livezwa ku-NL.
2. Incazelo ehambisanayo yohlamvu lwe-S355NL lwepuleti lensimbi:
S: insimbi yesakhiwo, N: isimo, inhlokodolobha L: izinga lamandla omthelela aphansi acacisiwe lapho izinga lokushisa lingaphansi kuka - 50 ° C
Ipuleti lensimbi le-S355ML [ubukhulu obungu-8-200mm] ukugoqa kwe-thermomechanical
Ipuleti lensimbi le-S355ML lilethwa lisesimweni sokugoqa ngomshini wokushisa
Izidingo Zokwakheka Kwamakhemikhali e-S355ML
C:≤0.14,Si:≤0.5,Mn：≤1.6,P:≤0.025,S：≤0.02,Nb:≤0.05,V:≤0.1,A l:≤0.02,Ti:≤0.05,Cr：≤0.3,Ni：≤0.5,Mo:≤0.1,Cu:≤0.55,N：≤0.015.
Ipuleti lensimbi le-S355ML liyinsimbi yokwakha egoqekile eshibilikayo eshibilikayo, eyingxenye yochungechunge lwamapuleti ensimbi aqinile aphansi. Liwumkhiqizo ogoqekile oyisicaba onobukhulu obungadluli ku-120mm kanye nomkhiqizo omude onobukhulu obungadluli ku-150mm. I-S isho insimbi yokwakha, i-355 ikhombisa ukuthi inani elincane lesivuno sobukhulu obufanele obungaphansi kuka-16mm lingu-355MPa, kanti i-M imelela ukulethwa kwayo, okungukuthi, ukugoqa okushisayo. Umthetho uwukuthi umthelela ekushiseni okungaphansi kwama-degrees angu-50 uboniswa uhlamvu olukhulu L. I-S355 iyinsimbi yokwakha engeyona ingxube.
Ububanzi bokusetshenziswa kwepuleti lensimbi le-S355ML
Ngaphezu kwensimbi ye-EN10,025-1, uhlelo lwensimbi oluchazwe ngokukhethekile kuleli zinga luphinde lusetshenziselwe izingxenye ezithwala umthwalo zezakhiwo ezihlanganisiwe ezisetshenziswa eduze kwamabhuloho, izindawo zokungena, amathangi okugcina, amathangi okuphakela amanzi, njll. kanye nokushisa okuphansi.
