    4. AISI / ASTM A681 D2 Qib Steel Forging

    Cua sov rau forging ntawm AISI D2 cuab tam steel yuav tsum
    tau ua li cas maj mam thiab uniformly. Tsau los ntawm thaum 1850 ° -1950 ° F thiab rhaub li feem ntau
    raws li tsim nyog, siv ceev xwmphem ua hauj lwm thaum lub kub dauv rau hauv qab no 1700 ° F (926 ℃). Tom qab D2
    tuag steel forging, txias maj mam nyob rau hauv txiv qaub, mica, qhuav tshauv los yog lub tshuab cua sov. AISI D2 steel
    yuav tsum nco ntsoov yuav annealed tom qab forging.

    5. D2 Tool Steel Thaum tshav kub kub kho mob

    • Thaum tshav kub kub kho mob

    ASTM D2 steels hlau yuav tsum tau preheated heev maj mam mus 815oC (1500oF) thiab ces kub yuav muab ntau zog rau 1010oC (1850oF). Lawv ces nyob rau hauv 1010oC (1850oF) rau 20 mus rau 45 feeb thiab cua txias (huab cua quenched).

    • Annealing

    Annealing ntawm D2 cuab tam steels khoom yuav tsum tau ua nyob rau 871 mus 898oC (1600 rau 1650oF) raws li los ntawm qeeb cub tawg txias ntawm 4.4oC (40oF) ib teev los yog less.after uas txias npaum li cas tej zaum yuav muab tau ntau zog. Haum ceev faj yuav tsum raug coj mus rau tiv thaiv kom txhob ntev carburization los yog decarburization.

    • Kev nyuaj siab relieving

    Thaum ntshaw kom daws qhov kab mob los ntawm machining, Thaum tshav kub kub D2 qib steel maj mam mus 1050 ° -1250 ° F, cia rau equalize, thiab ces txias nyob rau hauv tseem huab cua (hom relieving).

    • Preheat Ua ntej Yuav hardening

    Preheat maj mam mus 1350 ° -1450 ° F thiab tuav no kub kom txog thaum kawm qib steel D2 khoom yog uniformly rhuab.

    • hardening

    Tom qab meej preheating, tshav kub mus rau 1800 ° -1850 ° F. Tuav lub chaw ua hauj lwm daim nyob rau hardening kub kom txog thaum nws yog kiag li thiab uniformly rhuab.

    • quenching

    AISI D2 steel cuab tam khoom yog ib tug huab cua hardening hlau thiab yuav tsim hardness rau txias nyob rau hauv tseem huab cua. Kom tsis txhob scaling thiab tiv thaiv kom txhob decarburization ntawm lub chaw ua hauj lwm daim nto, tswj cua los yog lub tshuab nqus tsev furnaces yog pom zoo. Yog hais tias cov chaw rauv taws nte yog tsis muaj, pob hardening, ntsev da los yog wrapping daim nyob rau hauv stainless steel ntawv ci yuav muab ib co degree ntawm qhov chaw tiv thaiv nyob rau hauv lub hardening txheej txheem. Qhov yuav tsum tau tso cai kom txias rau 150F, los yog mus rau qhov twg lawv yuav tsum tau muaj nyob rau hauv lub liab qab tes, thiab ces temper tam sim ntawd.

    • tempering

    Lub tempering kub rau cov ntaub ntawv uas D2 steel tej zaum yuav varied raws li cov kev kawm hardness. D2 steels yuav tempered ntawm 204oC (400oF) ua kom tiav Rockwell hardness C ntawm 61 thiab nyob 537oC (1000oF) rau ib tug Rockwell hardness C ntawm 54.

    6. D2 Tool Steel Khoom Daim ntawv thov
     AISI qib D2 cuab tam steels yog siv rau ntev mus dhia Tooling kev siv, qhov twg hnav kuj yog ib qho tseem ceeb, xws li blanking los yog txoj kev ua hnub thiab xov dov tuag.
