42CrMo kuvanga ibyuma bidafite icyuma ni ubwoko bwicyuma gifite imbaraga nyinshi, ubukana bwinshi, hamwe no kwihanganira kwambara cyane, bikozwe42CrMo icyuma.Ifite imiterere yubukanishi, nkimbaraga nyinshi, gukomera kwinshi, kwihanganira kwambara cyane, no kurwanya ruswa, kandi irakwiriye gukora ibice byubukanishi nibikoresho bifite umutwaro mwinshi, imbaraga nyinshi, hamwe nibisabwa kwambara cyane.42CrMo kuvanga imiyoboro idafite ibyuma zikoreshwa cyane mubice nkindege, ikirere, ibinyabiziga, kubaka ubwato, peteroli, imiti, metallurgie, ubwubatsi, nubukanishi.
1. Ibisobanuro byo kuvura ubushyuhe kuri42CrMo icyuma kitagira icyumanibi bikurikira: gushyushya ubushyuhe 1150 ~ 1200 ° C, gutangira ubushyuhe 1130 ~ 1180 ° C, nubushyuhe burangira> 850 ° C, φ> Kuri 50mm, gukonja buhoro.
2. Guhindura ibisobanuro: Guhindura ubushyuhe ni 850 ~ 900 ° C, hamwe no gukonjesha umwuka nyuma yo gusohoka.
3. Ubushyuhe bwo hejuru Ubushyuhe bwo hejuru: Ubushyuhe 680-700 ° C, umwuka ukonje nyuma yo gusohora itanura.
4. Kuzimya no gutondeka ibisobanuro: gushyushya ubushyuhe 680-700 ° C, kuzimya ubushyuhe 840-880 ° C, gukonjesha amavuta, ubushyuhe bwa 580 ° C, gukonjesha amazi cyangwa amavuta, ubukana ≤ 217HBW.
5. Ibisobanuro ku kuzimya ubushyuhe no kuvura bikaze: kuzimya ubushyuhe 900 ° C, ubushyuhe bwo hejuru 560 ° C, ubukana (37 ± 1) HRC6, kuzimya induction hamwe nubushyuhe bwihariye: kuzimya ubushyuhe 900 ° C, ubushyuhe bwa 150-180 ° C. , gukomera 54-60HRC.
6. 42CrMo ibyuma bikorerwa imiti ya kirogenike, ishobora kugwa karbide ya ultrafine ikwirakwijwe cyane na martensite yazimye.Nyuma yubushyuhe buke kuri 200 ℃, karbide ultrafine irashobora guhinduka karbide
