BS EN 42CrMo4 |  1,7225 aloyi Engineering Zitsulo

Short Description:

BS EN 42crmo4 Alloy Steel is a common chromium-molybdenum steel that usually used after quenchedand tempered, with high intensity, high hardenability. BS EN 42CrMo4round steel has better performance than 34CrMo4 steel due to the carbonand chromium content is higher. 42CrMo4 alloy steel has higher strength and hardenability. The 42CrMo4 alloy material alsohas high fatigue strength and good low-temperature impact toughness. The temper brittleness is not obvious. Although 42CrMo4 steel is mo...

    5. Kutentha Chithandizo cha 42CrMo4 Steels

    Annealing wa 42CrMo4 Steels

    • Kutentha zitsulo 42CrMo4 wosula zitsulo pang'onopang'ono bwinobwino kuti 800-850 ° C;

    • Kuziziritsa pang'onopang'ono mu ng'anjo ndi kutentha 480 °;

    • Complete annealing zitsulo mu mlengalenga.

    Kuzimitsidwa ndi mtima (Q + T)

    • Kutentha 42CrMo4 zitsulo pang'onopang'ono 880 ° C;

    • Zilowerere pa kutentha uyu ndiye kuzima mu mafuta;

    • Mtima mwamsanga 42CrMo4 kutentha zitsulo kuchitiridwa chipinda (20 ° C);

    • Kutenthetsa uniformly kuti kutentha yabwino 560 ° C;

    • Kutapa pa 42CrMo4 zinthu ng'anjo ndi ozizira mu mlengalenga.

    6. kulipira wa 42CrMo4 aloyi Zitsulo

    • Preheat 42CrMo4 zomangamanga zitsulo uniformly ndi pang'onopang'ono;

    • Zomwe kulipira kutentha kwa 1150-1200 ° C.

    • Nthaŵi zonse kulipira kutentha pamwamba osachepera 850 ° C

    7.Weldability

    Engineering


    zitsulo 42CrMo4 ali okha okha weldability. Preheating kuti 200-300 ° C ndi
    mpofunikila; malire chapamwamba sayenera kuposa chifukwa cha
    chiopsezo cha kuwonongeka kwa chrome wosanjikiza.

    Aloyi zitsulo 42CrMo4
    akhoza mikangano welded. Komabe, kusamalitsa ndi zofunika kuti
    kuchepetsa mapangidwe microstructures osafunika mu zone welded.

    8.Application wa 42CrMo4 aloyi Steels

    EN


    42CrMo4 aloyi zitsulo chimagwiritsidwa ntchito zomangamanga zitsulo, monga
    ngati: kupanga mitundu yosiyanasiyana ya makina, galimoto, migodi yopuma mbali
    ya gearwheel a injini, ndi galimoto zida za supercharger, ndi
    kulumikiza kulanda, ndi pinchock pansi pa kuthamanga, mbali mphamvu
    ntchito sitima, ozizira anapanga fastener zigawo, migodi, magiya,
    kubowola makolala kwa kufufuza mafuta, etc.
