    5. D2 Tool Karfe Heat jiyya

    • Heat jiyya

    ASTM D2 steels gami da ya kamata a preheated sosai sannu a hankali don 815oC (1500oF) sa'an nan zazzabi za a iya karu zuwa 1010oC (1850oF). Suna nan da aka gudanar a 1010oC (1850oF) for 20 zuwa 45 minutes da kuma iska sanyaya (iska ta kasu).

    • Annealing

    Annealing na D2 kayan aiki steels abu ya kamata a yi a 871 zuwa 898oC (1600 zuwa 1650oF) bi jinkirin makera sanyaya a 4.4oC (40oF) awa daya ko less.after wanda sanyaya kudi iya ƙara. Dace sauna dole ne za a dauka don hana wuce kima carburization ko decarburization.

    • danniya ya ɗauke

    Lokacin da kyawawa don ya taimaka wa damuwa na machining, zafi D2 sa karfe sannu a hankali zuwa 1050 ° -1250 ° F, damar equalize, sa'an nan kwantar a yanzu iska (Iri ya ɗauke).

    • Preheat Kafin Don hardening

    Preheat sannu a hankali zuwa 1350 ° -1450 ° F da kuma rike a wannan zafin jiki har aji karfe D2 abu ne gaba ɗaya mai tsanani.

    • hardening

    Bayan na sosai preheating, zafi don 1800 ° -1850 ° F. Riƙe aikin yanki a hardening zafin jiki har shi ne gaba daya da kuma gaba ɗaya mai tsanani.

    • quenching

    Aisi D2 karfe kayan aiki abu ne mai iska hardening karfe da kuma za su ci gaba taurin kan sanyaya a yanzu iska. Don kauce wa hawa da kuma hana decarburization na aikin yanki surface, sarrafawa yanayi ko injin Tanderu suna shawarar. Idan wadannan Tanderu ba su da samuwa, Pack hardening, gishiri baho ko wrapping da yanki a bakin karfe tsare zai samar da wani mataki na surface kariya a cikin hardening tsari. Sassa kamata a yarda su kwantar wa 150F, ko zuwa inda za su iya a gudanar a danda hannu, sa'an nan zafin nan da nan.

    • Tempering

    A tempering zafin jiki a kan abu D2 karfe iya bambanta bisa ga so daga bãyan wancan. D2 steels za a iya zafin a 204oC (400oF) domin cimma Rockwell C taurin 61 da kuma a 537oC (1000oF) ga wani Rockwell C taurin 54.

    6. D2 Tool Karfe Material Aikace-aikacen
     Aisi sa D2 kayan aiki steels aka yi amfani ga dogon gudu tooling aikace-aikace, inda sa juriya da muhimmanci, kamar blanking ko kafa mutu da kuma thread mirgina ya mutu.

    Wasu babban aikace-aikace na D2 kayan aiki karfe ne a matsayin kasa:
