GCr15 zafi birgima karfe zagaye sanduna

GCr15  ƙarfe ne na gama gari wanda ake amfani dashi don samar da ƙwallaye da zoben ɗamara. Samfurin yana da halaye na nau'in nau'i-nau'i-nau'i-nau'i, ƙananan kashi na abubuwa masu cutarwa, tsabta mai tsabta, da rarraba carbide mai kyau, kyakkyawan yanayi. Har ila yau, yana da halaye na fadi da ikon yinsa, filastik, barga zafi-jiyya ingancin, uniform, da kuma high taurin, high lalacewa juriya, high ƙarfi na taba gajiya. Yana da kyawawan kayan aikin injin bayan spheroidize annealing. GB GCr15 qazanta karfe ne GB misali Alloy Bearing karfe, Yana cikin high quality-carbon, gami chromium, manganese karfe. GB GCr15 Properties ne chromium, manganese gami karfe bayani dalla-dalla. GCr15 yayi daidai da AISI 52100, DIN 100Cr6. Yawancin aikace-aikace na iya maye gurbin juna.
