1) Tšepe ea gear ea 42CrMo e na le litšobotsi tsa matla a phahameng, bokhoni bo phahameng ba ho thatafala, ho tiea hantle, ho fetoha ho honyenyane nakong ea ho tima, matla a phahameng a ho thekesela le matla a tšoarellang mochesong o phahameng.

E sebelisetsoa ho etsa li-forging tse hlokang matla a holimo le likarolo tse kholoanyane tse timmeng le tse halefisitsoeng ho feta tšepe ea 35CrMo, tse kang: li-gear tse kholo bakeng sa ho hula ha locomotive, li-gear tsa phetisetso ea supercharger, li-gear tsa sejana sa khatello, li-axle tse ka morao, lithupa tse hokelang tse jereng haholo le liliba. E ka boela ea sebelisoa bakeng sa li-joints tsa liphaephe tsa ho tjheka tse tebileng ka oli le lisebelisoa tsa ho tšoasa litlhapi tse ka tlase ho 2000m; 'me e ka sebelisoa bakeng sa liforomo tsa mechini e kobehang, jj.

2) Tšepe ea gear ea 20CrMnTiH ke tšepe e etsang carburizing e nang le ts'ebetso e ntle, bokhoni bo phahameng ba ho thatafala, bokaholimo bo thata le bo sa tsofaleng le karolo e ka hare e thata kamora ho etsa carburizing le ho tima, ho ba thata ha tšusumetso mochesong o tlase, bokhoni bo mahareng ba ho tjheseletsa, 'me e ka tjheseletsa kamora ho etsa hore e be bonolo.

E sebedisetswa ho etsa dikarolo tsa bohlokwa tse nang le karolo e tshekaletseng ya <30mm tse mamellang meroalo e lebelo le phahameng, e mahareng kapa e boima, tshusumetso le kgohlano; tse kang: digeri, digeri tse leketlileng, dihlooho tse tshekaletseng tsa shaft ya gear, jj. Ke tshepe e nkelang sebaka sa 18CrMnTi, e sebediswang haholo e le dikarolo tse tshekaletseng. E sebediswa diindastering tsa dikoloi le tsa diterekere tse nang le karolo e ka tlase ho 30mm; ke karolo ya bohlokwa e tshekaletseng e jereng meroalo e lebelo le phahameng, e mahareng kapa e boima mme e ka angwa ke kgohlano le kgohlano;
