Chitoliro chachitsulo cha EN10210 S355J2H

Posachedwapa, kasitomala anabwera ku fakitale kudzaona S355J2chitoliro cholumikizidwa, ulendo wonse, ogulitsa anafotokoza moleza mtima.S355J2HChitoliro chachitsulo cha ERW ndi chitoliro chachitsulo cha kaboni-manganese chapamwamba kwambiri chomwe chimalimbana bwino ndi kugwedezeka. Zinthuzi zimagwiritsidwa ntchito kwambiri pakupanga nyumba monga nyumba, milatho, misewu ikuluikulu, ndi mitundu ina ya ntchito zomanga.

Mapaipi achitsulo a S355J2H amapangidwa pogwiritsa ntchito njira yolumikizira magetsi (ERW), yomwe imaphatikizapo kupanga mbale zachitsulo zathyathyathya kukhala mapaipi kenako n’kulumikiza mipata. Kapangidwe ka mankhwala a chitoliro chachitsulo cha S355J2H ERW kamakhala ndi kaboni, manganese, silicon, phosphorous, ndi sulfure, ndipo mphamvu yocheperako yotulutsa ndi 355 N/mm². Chitolirochi chilinso ndi mphamvu zabwino zamakanika, ndi mphamvu yayikulu yolumikizira ya 510-680 N/mm². Chili ndi kuthekera kolumikizana bwino kwambiri ndipo mpweya wake wochepa umathandiza kuchepetsa chiopsezo cha ming'alu yopangika panthawi yolumikizira. Chimodzi mwazabwino zazikulu za chitoliro chachitsulo cha S355J2H ERW ndi kukana kwake kwakukulu. Izi zimapangitsa kuti chigwiritsidwe ntchito pomwe mapaipi amatha kugwedezeka ndi katundu wolemera kapena kugwedezeka. Kuphatikiza apo, kufanana kwa makulidwe a khoma la chitoliro ndi malo osalala amkati ndi akunja zimathandiza kuti kapangidwe kake kakhale kolimba komanso kosavuta kuyika. S355J2HChitoliro chachitsulo cha ERWimapezeka m'makulidwe ndi kutalika kosiyanasiyana, zomwe zimapangitsa kuti ikhale yogwiritsidwa ntchito m'njira zosiyanasiyana. Itha kugwiritsidwa ntchito kunyamula madzi, mpweya kapena zinthu zolimba ndipo, chifukwa cha mphamvu zake zambiri, ingagwiritsidwenso ntchito pazifukwa za kapangidwe kake. Mwachidule, chitoliro chachitsulo cha S355J2H ERW ndi chinthu chodalirika komanso cholimba chomwe chingagwiritsidwe ntchito pa ntchito zosiyanasiyana zomanga. Kukana kwake kugwedezeka kwambiri, makhalidwe ake abwino a makina komanso kusinthasintha kwake kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana.
