42CrMo ingxubevange yensimbi ipayipi nekhono luhlobo lwepayipi lensimbi elinamandla amakhulu, ubulukhuni obuphezulu, nokumelana nokugqoka okuphezulu, okwenziwe42CrMo insimbi ye-alloy.Inezici ezinhle zemishini, njengamandla aphezulu, ukuqina okuphezulu, ukumelana nokugqoka okuphezulu, nokumelana nokugqwala okuphezulu, futhi ifanele ukukhiqiza izingxenye zemishini namathuluzi anomthwalo omkhulu, amandla aphezulu, kanye nezidingo zokugqoka okuphezulu.42CrMo ingxubevange amapayipi ensimbi nekhono asetshenziswa kakhulu emikhakheni efana nezindiza, i-aerospace, izimoto, ukwakha umkhumbi, uphethiloli, amakhemikhali, i-metallurgy, ukwakhiwa, kanye nokukhiqizwa kwemishini.
1. Imininingwane yokwelapha ukushisa42CrMo ithubhu yensimbi engenamthungozimi kanje: izinga lokushisa lokushisa 1150 ~ 1200 ° C, izinga lokushisa lokuqala 1130 ~ 1180 ° C, kanye nokushisa kokugcina>850 ° C, φ> Ku-50mm, ukupholisa kancane.
2. Ukucaciswa okujwayelekile: Izinga lokushisa elijwayelekile lingu-850 ~ 900 ° C, ngokupholisa komoya ngemva kokukhishwa.
3. Ukucaciswa kokushisa okuphezulu kwezinga lokushisa: Izinga lokushisa elingu-680-700 ° C, umoya opholile ngemva kokukhishwa kwesithando somlilo.
4. Ukucaciswa kokucisha kanye nokushisa: ukushisa kwangaphambi kokushisa 680-700 ° C, ukushisa okucisha 840-880 ° C, ukupholisa kwamafutha, izinga lokushisa lokushisa 580 ° C, ukupholisa kwamanzi noma uwoyela, ubulukhuni ≤ 217HBW.
5. Ukucaciswa kwe-sub-temperature quenching kanye nokwelashwa okuqinisayo: izinga lokushisa lokucisha elingu-900 ° C, izinga lokushisa elingu-560 ° C, ubulukhuni (37 ± 1) HRC6, ukucima ukungeniswa kanye nokucaciswa kokushisa: izinga lokushisa lokucisha elingu-900 ° C, izinga lokushisa elingu-150-180 ° C. , ubulukhuni 54-60HRC.
6. Insimbi ye-42CrMo ingaphansi kokwelashwa kwe-cryogenic, okungase kubangele ama-ultrafine carbides ahlakazeke kakhulu kusukela ku-martensite ecishiwe.Ngemuva kokushisa okuphansi kwezinga lokushisa ku-200 ℃, lawa ma-carbides angama-ultrafine angaguqulwa abe ama-carbides.
