Abubuwan da aka fi amfani da su:45, 40Cr, 40CrNi

Siffofin: Taurin haƙori yana da girma HRC = 48-55, ƙarfin lamba yana da girma, kuma juriya na lalacewa yana da kyau.Cibiyar haƙori tana kula da tauri bayan quenching da tempering, yana da tasiri mai kyau juriya da ƙarfin ɗaukar nauyi.An rage daidaito da rabi, har zuwa matakin daidaito na 7.Ya dace da samarwa da yawa, irin su matsakaici-gudu da na'urorin watsawa na matsakaici don motoci, kayan aikin injin, da sauransu.

1.2.2 Lokacin amfani da ƙananan ƙarfe na carbon: Ƙirƙira blank → daidaitawa → m yanke → quenching da tempering → fine yankan → carburizing da quenching → ƙananan zafin jiki tempering → hakori nika.Har zuwa matakan 6 da 7.

Abubuwan da aka saba amfani da su;20Cr, 20CrMnTi, 20MnB, 20CrMnTo Features: Taurin saman haƙori da ƙarfin ɗaukar nauyi.Matsakaicin yana da kyau tauri da juriya mai tasiri.Ya dace da babban sauri, nauyi mai nauyi, watsawa mai yawa ko lokuta tare da ƙayyadaddun buƙatun tsarin, azaman babban kayan watsawa na locomotives da gear jirgin sama.

2. Karfe:

Lokacin da diamita gear d>400mm, tsarin yana da rikitarwa, kuma ƙirƙira yana da wahala, ana iya amfani da kayan ƙarfe na simintin ZG45.ZG55 don daidaitawa.Normalisation, quenching da tempering.
