1) Simbi yesimbi ye42CrMo ine hunhu hwesimba guru, kugona kuomesa zvinhu zvakanyanya, kusimba kwakanaka, kushanduka kudiki panguva yekudzima, simba guru rekukambaira uye simba rinogara kwenguva refu pakupisa kwakanyanya.

Inoshandiswa kugadzira maforging anoda simba rakawanda uye zvikamu zvakakura zvakadzimwa uye zvakapfava kupfuura simbi ye35CrMo, zvakaita se: magiya makuru ekutakura locomotive, magiya ekutumira supercharger, magiya emidziyo yepressure, maaxle ekumashure, tsvimbo dzekubatanidza dzakaremerwa zvakanyanya uye masipiringi. Inogona zvakare kushandiswa kumajoini emapaipi ekuboorera akadzika mutsime remafuta uye maturusi ekuredza ari pasi pe2000m; uye inogona kushandiswa kumaforoma emuchina wekukotamisa, nezvimwewo.

2) Simbi yegiya ye20CrMnTiH isimbi inokabhurisa ine mashandiro akanaka, inogokora zvakanyanya, ine pamusoro pakaoma uye inotsungirira kupera simba uye ine pakati pakasimba mushure mekukabhurisa nekudzima, inogokora tembiricha yakaderera, ine simba repakati nepakati rekukabhurisa, uye inogona kusundirwa mushure mekukabhurisa. Kugona kushanda zvakanaka.

Inoshandiswa kugadzira zvikamu zvakakosha zvine chikamu chepakati <30mm zvinotsungirira mitoro yekumhanya, yepakati kana inorema, kurovera nekukweshana; zvakaita se: magiya, magiya ekutenderedza, magiya ekuyambuka shaft, nezvimwewo. Isimbi inotsiva 18CrMnTi, iyo inoshandiswa zvakanyanya sezvikamu zvakakangwa. Inoshandiswa mumaindasitiri emotokari nematrakita ane chikamu chiri pasi pe30mm; chikamu chakakosha chakakangwa chinotakura mitoro yekumhanya, yepakati kana inorema uye chinogona kurovera nekukweshana;
