Bayani na 12L14 Karfe-Yanke Kyauta
A karfe tare da abun ciki sama da na yau da kullun na sulfur da phosphorus da aka yi niyya don ƙirƙirar sassa don kayan aikin injin atomatik mai sauri da atomatik. Ana samar da ƙarfe mai yanke kyauta a cikin nau'in sanduna, kuma yana ƙunshe da 0.08-0.45 bisa dari carbon, 0.15-0.35 bisa dari silicon, 0.6-1.55 bisa dari manganese, 0.08-0.30 bisa dari sulfur, da 0.05-0.16 bisa dari na phosphorus. Babban abun ciki na sulfur yana haifar da samuwar hadawa (misali, manganese sulfide) da aka zubar tare da hatsi. Waɗannan abubuwan haɗawa suna sauƙaƙe shear da haɓaka niƙa da samuwar guntu cikin sauƙi. Don waɗannan dalilai, ƙarfe mai yanke kyauta wani lokaci ana haɗa shi da gubar da tellurium.
12L14 wani nau'i ne na resulfurized da rephosphorized carbon karfe don yankan kyauta da aikace-aikacen machining. Ƙarfe na tsari (ƙarfe ta atomatik) yana da kyakkyawan machinability da ƙananan ƙarfi saboda abubuwan da aka haɗa da su kamar Sulfur da Lead, wanda zai iya rage juriya na yankewa da inganta ƙaddamarwa da daidaitattun sassa na inji. 12L14 karfe da aka yadu amfani a yi na ainihin kayan aiki sassa, mota sassa da kuma muhimmanci sassa na daban-daban irin kayan, hankula aikace-aikace ciki har da bushings, shafts, abun da ake sakawa, couplings, kayan aiki da sauransu.
