42CrMo ingxubevange umbhobho yentsimbi engenamthungo luhlobo lombhobho wensimbi onamandla amakhulu, ubunzima obuphezulu, kunye nokumelana nokugqoka okuphezulu, okwenziwe42CrMo intsimbi yengxubevange.Ineempawu ezintle zoomatshini, ezinje ngokuqina okuphezulu, ukuqina okuphezulu, ukumelana nokunxiba okuphezulu, kunye nokuxhathisa okuphezulu kwe-corrosion, kwaye ifanelekile ukwenza iinxalenye zoomatshini kunye nezixhobo ezinomthwalo omkhulu, amandla aphezulu, kunye neemfuno zokunxiba eziphezulu.Imibhobho yentsimbi engenamthungo ye-42CrMo zisetyenziswa kakhulu kwimimandla enje ngenqwelomoya, i-aerospace, izithuthi, ukwakhiwa kweenqanawa, i-petroleum, iikhemikhali, isinyithi, ulwakhiwo, kunye nokuveliswa koomatshini.
1. Iinkcukacha zonyango lobushushu42CrMo ityhubhu yentsimbi engenamthungozezi zilandelayo: ubushushu bokufudumala 1150 ~ 1200 ° C, ukuqala kweqondo lokushisa 1130 ~ 1180 ° C, kunye nokuphela kokushisa>850 ° C, φ> Kwi-50mm, ukupholisa okucothayo.
2. Inkcazo yesiqhelo: Iqondo lokushisa eliqhelekileyo li-850 ~ 900 ° C, kunye nokupholisa umoya emva kokuphuma.
3. Inkcazo yobushushu obuphezulu bobushushu: Ubushushu bobushushu 680-700 ° C, umoya upholile emva kokuphuma kwesithando somlilo.
4. Ukucima kunye neenkcukacha zokushisa: ukushisa kwangaphambi kokushisa kwe-680-700 ° C, ukucima ukushisa kwe-840-880 ° C, ukupholisa ioli, ukushisa kweqondo lokushisa kwe-580 ° C, ukupholisa amanzi okanye ioli, ubunzima ≤ 217HBW.
5. Inkcazo yokucima ubushushu obuphantsi kunye nonyango oluqinisayo: ukucima ubushushu be-900 ° C, ubushushu bokufudumala 560 ° C, ukuqina (37 ± 1) HRC6, ukucima ukucima kunye nokunciphisa ubushushu: ukucima ubushushu be-900 ° C, ukushisa kwe-150-180 ° C. , ubunzima 54-60HRC.
6. I-42CrMo yensimbi iphantsi konyango lwe-cryogenic, olunokuthi lugqithise kakhulu i-ultrafine carbides esuka kwi-martensite ecinyiweyo.Emva kobushushu obuphantsi kwi-200 ℃, ezi carbides ze-ultrafine zinokuguqulwa zibe yi-carbides.
