Unoziva here kuti ndeipi iri nani, American standard steel plate A36 kana Q235B?
Shandong Kungang Metal Technology Co., Ltd. inotarisa pakugadzirwa uye kutengesa kwesimbi ndiro, uye isu tine ruzivo rwakapfuma uye mukurumbira mumusika.Paunenge uchitenga mahwendefa esimbi, zvakajairika kunzwa kuenzanisa pakati peAmerican standard steel plate A36 uye Q235B.Aya marudzi maviri emahwendefa esimbi ane mimwe misiyano mukushanda.Tichakupa tsananguro yakadzama yekushanda kwavo kubva pamaonero akawanda uye kukubatsira kuita sarudzo dzehungwaru dzekutenga.Kutanga, ngatienzanise aya mahwendefa maviri esimbi maererano nesimba.Kusimba kwegoho reAmerican standard steel plate A36 ndeye 250MPa, uye simba rekusimba i400-550MPa, ukuwo simba regoho reQ235B simbi ndiro 235MPa, uye simba rekusimba iri 375-500MPa.Kubva pane idzi data, zvinogona kuoneka kuti simba reAmerican standard steel plate A36 rakakwira zvishoma pane Q235B, izvo zvinoita kuti ive yakakodzera kushandiswa mumapurojekiti anoda kutsigirwa kwesimba repamusoro.
Chechipiri, ngatienzanise makemikari avo.Kemikari yeAmerican standard steel plate A36 ine kabhoni (C) inosvika 0.25%, sulfur (S) ye0.05%, uye phosphorus (P) ye0.04%, nepo Q235B simbi ndiro ine kabhoni (C) ye0.22. %, zvishoma (S) zviri 0.05%, uye phosphorus (P) zviri 0.045%.Kubva pakuona kwekuumbwa kwemakemikari, hapana misiyano yakawanda pakati pemhando mbiri idzi dzesimbi mahwendefa, ose ari ekabhoni mutoro structural simbi uye ane yakanaka weldability uye machinability.
Pamusoro pezvo, pane mimwe misiyano mukuramba ngura pakati peAmerican standard steel plate A36 uye 0235B.Nekuda kweiyo yakakwira kabhoni yeAmerican standard steel plate A36, inoita ngura munzvimbo dzine hunyoro hwepamusoro.Q235B simbi ndiro ine yakanaka corrosion kuramba munzvimbo dzakajairika.Kune akajairwa mainjiniya mapurojekiti, kusarudza Q235B simbi ndiro inogona kudzivirira zvirinani chimiro kubva mukuora.Mushure meizvozvo, isu tinofanirawo kufunga nezvechinhu che weldability.Iyo American standard steel plate A36 ine yakanaka weldability uye inogona kubatanidzwa uchishandisa yakajairwa welding nzira.Nekudaro, Q235B simbi ndiro ine mamwe matambudziko ewelding nekuda kwekuderera kwayo kabhoni.Mune mamwe mapurojekiti anoda yakakwirira welding mhando, kusarudza American standard steel plate A36 inogona kuve yakavimbika.Pakazere, pane mimwe misiyano pakati peAmerican standard steel plate A36 neQ235B maererano nesimba, chimiro chemakemikari, corrosion resistance, uye coalability.Kana iwe uchida tsigiro yesimba repamusoro uye zvirinani kuramba kwecorrosion, unogona kusarudza American standard steel plate A36.Kana iwe uine zvakakwirira zvinodikanwa zvewelding mhando, unogona kusarudza Q235B simbi ndiro.
Shandong Kungang Metal Technology Co., Ltd inopa zvemhando yepamusoro simbi ndiro zvigadzirwa.Kugamuchirwa kubvunza kana kushanyira webhusaiti yedu kuti uwane rumwe ruzivo.Tinotarisira kushanda pamwe chete
uye kugadzira kungwara!
