    AISI 8620 Zitsulo


    ndi zitsulo otsika aloyi faifi tambala, chromium, molybdenum mlandu kuumitsa,
    zambiri amaperekedwa mu ngati chikhalidwe adagulung'undisa ndi munthu pazipita kuuma HB


    255max. SAE zitsulo 8620 amapereka mkulu kunja mphamvu ndi chabwino mkati
    mphamvu, kupanga kwambiri kuvala kugonjetsedwa. AISI 8620 zitsulo ali apamwamba
    pakati mphamvu kuposa sukulu 8615 ndi 8617.

    SAE 8620 aloyi zitsulo ndi
    kusintha pa kuumitsa mankhwala, zimene zikutanthauza kusintha kwa
    katundu mlandu / pachimake. Pre oumitsidwa ndi mtima (uncarburized) 8620 akhoza
    kukhala pamwamba zina kuumitsidwa nitriding koma sadzakhala kuyankha
    mogwira mtima kwa lawi kapena kupatsidwa ulemu kuumitsa chifukwa chake otsika mpweya
    okhutira.

    Zitsulo 8620 ndi yosayenera ntchito yomwe amafuna
    kuphatikiza kulimba ndi kuvala kukana. Kalasi ichi ambiri
    aziwapatsa m'bala chonse.


    1. AISI 8620 Zitsulo Wonjezerani manambala

    8620 Round Bar: m'mimba mwake 80mm - 1200mm
    8620 Zitsulo mbale: makulidwe 10mm - 1500mm × m'lifupi 200mm - 3000mm
    8620 Square Bar: 140mm - 460mm
    8620 machubu komanso zilipo ndi pempho lanu mwatsatanetsatane.
    Pamwamba kumaliza: Black, Loyipa machined, Kutembenuka kapena pa amafuna kupatsidwa.
