42CrMo alloy isina musono simbi pombi imhando yepombi yesimbi ine simba rakawanda, kuoma kwakakwirira, uye yakakwirira kupfeka kuramba, yakagadzirwa42CrMo alloy simbi.Iine zvinhu zvakanaka zvemuchina, senge kusimba kwepamusoro, kusimba kwepamusoro, kukwirira kupfeka kusagadzikana, uye yakakwirira corrosion kuramba, uye inokodzera kugadzira mekiniki zvikamu uye maturusi ane mutoro wakakwira, simba rakawanda, uye yakakwirira kupfeka kuita zvinodiwa.42CrMo alloy isina musono simbi mapaipi anoshandiswa zvakanyanya muminda senge ndege, aerospace, mota, kuvaka ngarava, peturu, makemikari, simbi, kuvaka, uye michina kugadzira.
1. The kupisa kurapwa nokurondedzerwa nokuda42CrMo isina musono simbi chubhuzvinotevera: kupisa tembiricha 1150 ~ 1200 ° C, kutanga tembiricha 1130 ~ 1180 ° C, uye kupera tembiricha> 850 ° C, φ> Pa50mm, kunonoka kutonhora.
2. Normalizing tsanangudzo: Normalizing tembiricha iri 850 ~ 900 ° C, nemhepo kutonhora pashure pokubuda.
3. High tembiricha tempering tsanangudzo: Tempering tembiricha 680-700 ° C, mweya wakatonhodzwa pashure choto.
4. Kudzima uye kudzikamisa maitiro: preheating tembiricha 680-700 ° C, quenching tembiricha 840-880 ° C, mafuta kutonhora, tempering tembiricha 580 ° C, mvura kana mafuta kutonhora, kuoma ≤ 217HBW.
5. Tsanangudzo ye sub tembiricha quenching uye toughening kurapwa: quenching tembiricha 900 ° C, tempering tembiricha 560 ° C, kuoma (37 ± 1) HRC6, induction quenching uye tempering tsanangudzo: quenching tembiricha 900 ° C, tempering tembiricha 150-180 ° C. , kuoma 54-60HRC.
6. 42CrMo simbi inoiswa kune cryogenic kurapwa, iyo inogona kukonzeresa yakanyanya kupararira ultrafine carbides kubva kudzima martensite.Mushure mekudzikira-kupisa pa200 ℃, idzi ultrafine carbides dzinogona kushandurwa kuita carbides.
