2. Low carbon karfe tube
Ƙarfe mai ƙarancin carbon: Low-carbon karfe tare da carbon abun ciki na fiye da 0.15% ana amfani da shafts, bushings, sprockets, da kuma wasu filastik molds cewa bukatar high taurin da kyau lalacewa juriya a kan surface bayan carburizing da quenching da kuma low-zazzabi tempering. Bangaren Bayan carburizing da quenching da low-zazzabi tempering, da low-carbon karfe yana da wani tsari na high-carbon martensite a kan surface da low-carbon martensite a tsakiya, don tabbatar da cewa surface yana da high taurin da kuma high lalacewa juriya yayin da. cibiyar tana da taurin gaske. Kyakkyawan ƙarfi da ƙarfi. Ya dace da yin takalman birki na hannu, magudanan lefa, cokali mai yatsu na saurin gearbox, jigilar m gears, camshafts akan tarakta, madaidaitan ma'aunin dakatarwa, bushes na ciki da na waje na ma'auni, hannayen riga, kayan gyarawa da sauran sassa.

3. Matsakaici carbon karfe tube
Medium-carbon karfe: Carbon karfe tare da abun ciki na carbon na 0.25% zuwa 0.60%. 30, 35, 40, 45, 50, 55 da sauran maki na cikin matsakaici-carbon karfe. Saboda abun cikin lu'u-lu'u a cikin karfe yana ƙaruwa, ƙarfinsa da taurinsa sun fi da. Ana iya ƙara taurin sosai bayan quenching. Daga cikin su, 45 karfe shine mafi yawan al'ada. 45 karfe ne mai ƙarfi matsakaici-carbon quenched da tempered karfe, wanda yana da wani robobi da taurin, da kyau yankan aiki. Yana iya samun ingantattun kaddarorin inji ta hanyar quenching da jin zafi, amma taurin sa ba shi da kyau. Ana amfani dashi don kera sassa tare da buƙatun ƙarfin ƙarfi da matsakaicin ƙarfi. Yawancin lokaci ana amfani da shi a cikin ƙushewa da fushi ko yanayin daidaitacce. Domin sanya karfe ya sami taurin da ake bukata kuma ya kawar da ragowar damuwa, ya kamata a kashe karfe sannan a sanya shi cikin sorbite.
