303 mbale yachitsulo chosapanga dzimbiri
Kuchuluka kwa ntchito: petroleum, zamagetsi, mankhwala, mankhwala, nsalu zopepuka, chakudya, makina, zomangamanga, mphamvu za nyukiliya, zakuthambo, zankhondo ndi mafakitale ena! 303 ndi chitsulo chosapanga dzimbiri chosapanga chaulere chokhala ndi sulfure ndi selenium, motsatana. Amagwiritsidwa ntchito makamaka m'mapulogalamu omwe amafunikira kudulidwa kwaulere komanso kumaliza kwapamwamba. 303 Chitsulo chosapanga dzimbiri chimathandizira kudula komanso kukana kutentha kwambiri. Zabwino kwambiri zopangira ma lathes. Maboti ndi mtedza. 303 Chitsulo chosapanga dzimbiri ndi chitsulo chosapanga dzimbiri cha austenitic chaulere chosavala chosagwira asidi. Pofuna kupititsa patsogolo chitsulo ichi, molybdenum ikhoza kuwonjezeredwa kuchitsulo chosapitirira 0.60 ﹪, yomwe imatha kukana kutulutsa mpweya, ndipo mankhwalawa ali ndi machinability abwino komanso kukana kutentha. Kukana dzimbiri. Pambuyo pa makina opangidwa ndi .303 zitsulo zosapanga dzimbiri zatsekedwa ndi kupsinjika, mphamvu yamagetsi ndi 515MPa, zokolola ndi 205MPa, ndi elongation ndi 40%. Kuuma kwachitsulo chosapanga dzimbiri 303 HRB 90-100, HRC 20-25, Dziwani: HRB100 = HRC20 Nthawi yotumiza: Jan-19-2020
