Izinto ezingu-9 ze-cr2mo zensimbi evamile ye-Cr2 ebandayo isezimbonini ezisetshenziswa kakhulu ekwenzeni amakhaza agoqwe nge-roller ye-cold die kanye ne-punch njll kodwa abaningi bathi abazi mayelana ne-9 cr2mo indlela yokushisa ukushisa, ngakho-ke lapha ukukhuluma kakhulu mayelana nendlela yokwelapha ukushisa engu-9 cr2mo, ngethemba lokuba yi-spheroidizing annealing, 60 ~ 10 1, 600 1, 608, 608, 508, 608, 508 670, 500 kusuka ekupholiseni komoya; 2 ukucisha: izinga lokushisa lokushisa =880 ~ 900, ukupholisa okucishayo: ngokusho kwe-forging ehlukene kanye nezidingo ezahlukene, indawo yokupholisa efana namanzi e-PAG yokucisha amafutha oketshezi ingasetshenziswa.
Qaphela: Ama-forgings ayinsimbi ejwayelekile ye-Cr2.

3 Izinga lokushisa lephuzu elibalulekile (inani elilinganiselwe):Ac1 =740 C Ar1 =700 C Accm :850 C 4 Izicaciso ezijwayelekile zokuthambisa ngokucindezelwa okubandayo kungenalutho820 10) C 3 ~4h, ngesilinganiso sokupholisa esingu-.15 C/h, isithando somlilo siphola kancane sibe ku-650 C, 5 okucindezelwe okubandayo kungenalutho ukusuka kuhhavini ukupholisa kuya ekucacisweni kokuthambisa okuphothiwe820 10) C 3 ~4h, (720 10) C 6 ~8h, bese kuthi isithando somlilo siphole kancane sibe ngu-600 C,Isicaciso sokwejwayelekile: izinga lokushisa elijwayelekile 900 ~920 C, ubulukhuni 302-388HBW 7 Iqoqo isothermal spheroidizing0 ~3r8h09 Ukupholisa ~3r8h09 7O0-720 C 3 ~4h, ubulukhuni 217HBW, Pearlitic tissue grade 2-5,Isicaciso sokucisha kanye nokushisa kwe-8 forgings ye-mesh carbide grade 2 1. Ukushisa okucisha 830-850 C, ukuqina 62-65 HRC, ukushisa okuqinile 602 RC5 602 HRC 620 130 HRC. Ukushisa okucishayo 840-860 C, ubulukhuni 61-63 HRC, lokushisa lokushisa 150-170 C, ubulukhuni 60-62HRC.
