Abubuwan da aka yi amfani da su a cikin ɗigon abin nadi ana la'akari da su da ƙarfi mai ƙarfi, ƙarfin gajiyawa, juriya mai kyau da taurin tasiri. Gabaɗaya an yi shi da babban ƙarfe chromium na carbon. KamarGCr15, GCr15SiMn, GCr18Mo, G20CrNiMo, G20Cr2Ni4A.
1. GCr15: Kyakkyawan aikin gabaɗaya. Bayan quenching da fushi, taurin yana da girma kuma iri ɗaya ne, kuma juriya na lalacewa da juriya ga gajiyababba.Kyakkyawan aiki akan inji.
Aikace-aikace: Small da matsakaicin tef ɗin abin nadi.
Cibiyoyin mota, masu ragewa, kayan aikin injin, ƙafafun tasha na bushewa, injin juyawa, akwatunan gear, winches dawo da ginshiƙi, winches masu saurin gudu biyu, injin gabaɗaya, da sauransu.
2. GCr15SiMn: GCr15SiMn karfe ne gyare-gyaren karfe wanda ya dace da ƙara abun ciki na silicon da manganese bisa GCr15. Yana da kyau taurin iyawa, juriya, da iyaka na roba,tare da mafi kyawun juriya fiye da GCr15.
Aikace-aikace: Ltashinr da matsakaita-girma tapered bearings.
Juyin niƙa mai sanyi, masu rage tsutsotsi, masu rage jerin ZD, winches na shafi, winches masu maƙasudi da yawa na gudu, shunting winches, da sauransu.
3. GCr18Mo: Wani sabon nau'i ne na babban ƙarfin ƙarfi mai ɗaukar ƙarfe, na cikin jerin manyan ƙarfe na chromium mai ɗaukar ƙarfe. Idan aka kwatanta da GCr15 da GCr15SiMn, abun ciki na chromium yana ƙaruwa, ana ƙara molybdenum da ya dace, kuma ana amfani da ƙananan bainite isothermal quenching tsarin kula da zafi don samun ƙananan tsarin bainite da mafi girman ragowar abun ciki austenite,tare da mafi girman tasiri tauri da raunin karaya.
Aikace-aikace: Layi guda babba da matsakaita, jeri biyu, da nadi mai madaidaicin jeri huɗu .
Sanyi mirgine niƙa rolling, high-gudun dogo ƙafafun, kayan rage kaya, da dai sauransu.
4. G20CrNiMo:Ƙarfe ce ta alloy carburized. Bayan jiyya na carburization, farfajiyar tana da ƙarancin ƙarfi mai ƙarfi, juriya, da kuma tuntuɓar ƙarfin gajiya, yayin da yake riƙe da ƙarfi mai kyau a ainihin, wanda zai iya jure wa babban tasiri. Kyakkyawan hardenability da babban ƙarfi.
Aikace-aikace:Matsakaici zuwa babban jeri biyu, jeri huɗu masu madaidaicin abin nadi.
Rolling niƙa Rolling, niƙa a tsaye, Railway bearings, da dai sauransu.
5. G20Cr2Ni4A:Yana da wani high quality-alloy carburized karfe tare da high surface taurin, sa juriya, da lamba gajiya ƙarfi bayan carburization magani. A lokaci guda, yana riƙe da ƙarfi mai kyau a cikin ainihin kuma yana iya jure wa babban tasirin tasiri. G20Cr2Ni4A abu ya fi G20CrNiMo kayan.
Aikace-aikace:Large hudu jere tapered abin nadi bearings.
Rolling niƙa na karfe, niƙa na tsaye, bearings na dogo, da dai sauransu.
