42CrMo aloyi aloyi opanda zitsulo chitoliro ndi mtundu wa chitoliro chachitsulo chokhala ndi mphamvu zambiri, kuuma kwakukulu, ndi kukana kwambiri kuvala, zopangidwa42CrMo aloyi chitsulo.Ili ndi zida zabwino zamakina, monga kulimba mtima, kulimba kwambiri, kukana kuvala kwambiri, komanso kukana kwa dzimbiri, ndipo ndiyoyenera kupanga zida zamakina ndi zida zokhala ndi katundu wambiri, mphamvu zambiri, komanso zofunikira zamavalidwe apamwamba.42CrMo aloyi zitsulo mapaipi opanda msokonezo amagwiritsidwa ntchito kwambiri m'magawo monga ndege, zakuthambo, magalimoto, kupanga zombo, mafuta, mankhwala, zitsulo, zomangamanga, ndi kupanga makina.
1. The kutentha mankhwala specifications42CrMo chubu chachitsulo chosasunthikaali motere: Kutentha kutentha 1150 ~ 1200 ° C, kuyambira kutentha 1130 ~ 1180 ° C, ndi kutentha kotsiriza> 850 ° C, φ> Pa 50mm, kuzizira pang'onopang'ono.
2. Normalizing specifications: Normalizing kutentha ndi 850 ~ 900 ° C, ndi mpweya kuzirala pambuyo kumaliseche.
3. Kutentha kwakukulu kwa kutentha: Kutentha kwa kutentha kwa 680-700 ° C, mpweya utakhazikika pambuyo potulutsa ng'anjo.
4. Kuzimitsa ndi kutentha specifications: preheating kutentha 680-700 ° C, kuzimitsa kutentha 840-880 ° C, mafuta kuzirala, tempering kutentha 580 ° C, madzi kapena mafuta kuzirala, kuuma ≤ 217HBW.
5. Tsatanetsatane wa kutentha pang'ono kuzimitsa ndi toughening mankhwala: kuzimitsa kutentha 900 ° C, tempering kutentha 560 ° C, kuuma (37 ± 1) HRC6, induction quenching ndi tempering specifications: quenching kutentha 900 ° C, kutentha kutentha 150-180 ° C. , kuuma 54-60HRC.
6. Chitsulo cha 42CrMo chimakhala ndi chithandizo cha cryogenic, chomwe chingathe kutulutsa ma ultrafine carbides omwazika kwambiri kuchokera ku martensite wozimitsidwa.Pambuyo pa kutentha kwapakati pa 200 ℃, ma ultrafine carbides amatha kusinthidwa kukhala ma carbides.
