40CrNiMo Steel Round Bar

40CrNiMo amabha ensimbi ayindilinga ashisayo ashisayo

Insimbi ye-40CrNiMoA iyinsimbi ye-alloy yaseShayina, inamandla aphezulu, ukuqina nokuqina okuhle, futhi inozinzo olwa nokushisa ngokweqile, kodwa inokuzwela okuphezulu kwamaphuzu amhlophe, ukufutheka kanye nokushisela okubi. Ukushisa kuyadingeka ngaphambi kokushisela, futhi ukwelashwa kokucindezeleka kuyadingeka ngemva kokushisela.

Isingeniso somkhiqizo

Insimbi ye-40CrNiMoA isetshenziswa ngemva kokucisha nokushisa, futhi isetshenziselwa ukwenza izingxenye ezibalulekile ezidinga ipulasitiki enhle, amandla aphezulu kanye nosayizi omkhulu. Isibonelo, izinsimbi ezisindayo emishinini esindayo, izinsimbi zeturbine ezinobubanzi obungaphezu kwama-250 mm, ama-blades, ukuhanjiswa, izinsimbi, ama-crankshafts, amagiya, njll., nazo zingasetshenziselwa imiphini ye-rotor nama-blades asebenza emazingeni okushisa angaphezu kwama-400. °C.
Uchungechunge lwensimbi ye-Chrome-Moly low alloy luqukethe u-0.5% - 9% Cr no-0.5% - 1% Mo futhi ongaphansi kuka-0.20% wekhabhoni. I-40CrNiMoA, 4340 kanye ne-SNCM439 yizinto eziphansi ze-alloy chromoly steel materials ezivela kumazinga ahlukene.

I-4340 kanye ne-SNCM439 izindinganiso ezivela eMelika naseJapane ngokulandelana. Ezimweni eziningi zingaba izinto ezihlukile, ngaphandle uma kunenothi elikhethekile noma elisetshenziselwa inhloso ekhethekile. Umehluko wabo utholakala ikakhulukazi ezintweni zamakhemikhali, imininingwane iboniswe kanje:

Ukucaciswa kokwelashwa kokushisa

Ukushisa kokuqala kokucisha: 850 °C (Quenchant– uwoyela)
Izinga lokushisa elishisayo: 600 °C (Quenchant– amanzi, uwoyela)

Yayisetshenziswa lapho idinga izingxenye zezakhiwo eziqinile neziqinile eziqinile ezifana nama-ekseli esindayo, ama-shafts, amagiya esindayo, ama-spindle, amaphini, ama-studi, amabhawudi, ama-couplings, ama-sprockets, amaphinifa, ama-torsion bars, izinduku zokuxhuma. Lezi zinsimbi eziqinile eziqinile zisetshenziswe kakhulu ezindaweni ezifana nemboni yamakhemikhali kaphethiloli, ezezimoto, imishini yamandla esitimu kanye nezinye izinsizakalo zokushisa okuphezulu.
