1) I-42CrMo yensimbi yegiya inezici zamandla aphezulu, ikhono eliphezulu lokuqina, ukuqina okuhle, ukuguquguquka okuncane ngesikhathi sokucisha, amandla aphezulu okukhasa kanye namandla ahlala isikhathi eside ekushiseni okuphezulu.

Isetshenziselwa ukwenza ama-forging adinga amandla aphezulu kanye nezingxenye ezinkulu ezicishiwe neziqinile kunensimbi engu-35CrMo, njengalezi: amagiya amakhulu okudonsa kwesitimela, amagiya okuhambisa i-supercharger, amagiya omkhumbi ocindezelayo, ama-ekseli angemuva, izinduku zokuxhuma ezilayishwe ngokwedlulele neziphethu Ingasetshenziselwa futhi amapayipi okubhoboza amanzi ajulile kawoyela kanye namathuluzi okudoba ngaphansi kwama-2000m; futhi ingasetshenziselwa isikhunta semishini yokugoba, njll.

2) Insimbi yegiya engu-20CrMnTiH iyinsimbi egoqayo esebenza kahle, ikhono eliphezulu lokuqina, indawo eqinile futhi engagugi futhi iqinile ngemuva kokungcwatshwa nokucisha, ukuqina komthelela ophansi wokushisa okuphansi, amandla okushisela, futhi ingashiselwa ngemuva kokujwayelekile Okuhle. ukukwazi ukwenza izinto.

Isetshenziselwa ukukhiqiza izingxenye ezibalulekile ezine-cross-section <30mm ezimelana nesivinini esikhulu, esiphakathi noma esindayo, umthelela kanye nokungqubuzana; okufana nalokhu: amagiya, amagiya ensimbi, ama-cross-head shaft egiya, njll. Kuyinsimbi ethatha indawo ye-18CrMnTi, esetshenziswa kabanzi njengezingxenye ze-carburized. Isetshenziswa ezimbonini zezimoto nezagandaganda ezinesigaba esingaphansi kuka-30mm; iyingxenye ebalulekile ye-carburized ethwala imithwalo yesivinini esikhulu, ephakathi noma esindayo futhi engaphansi komthelela nokungqubuzana;
