35CrMnSiA zafi birgima karfe takardar

35CrMnSiA ƙaramin ƙarfe ne mai ƙarfi mai ƙarfi. Bayan zafi magani, yana da kyau m inji Properties, high ƙarfi, isa tauri, hardenability, weldability (preheating kafin waldi), da kuma aiki formability, amma yana da kyau lalata juriya da Low hadawan abu da iskar shaka juriya, kullum amfani bayan low zazzabi tempering ko austempering. Ƙarfin tsarin ƙarfi mai ƙarfi da zafin jiki. Yana da babban ƙarfi da tauri, babban ƙarfin ƙarfi, matsakaicin nakasar sanyi na filastik, da kyakkyawan aikin yankewa. Akwai hali zuwa ga gutsuttsura, kuma tasirin taurin kai ba shi da kyau. A waldi yi ne mafi alhẽri, amma a lokacin da kauri ne girma fiye da 3mm, shi ya kamata a preheated zuwa 150 ℃ farko, da zafi magani ake bukata bayan waldi. Yawanci ana amfani dashi bayan tempering.
