    Yuav ua li cas yog 52100 kabmob steel?

    AISI / ASTM

    52100 kabmob steel yog ib tug siab carbon, chromium uas muaj tsawg hlau
    steel uas yog los ntawm hardening thiab muab sau nyob rau hauv particular rau kev siv raws li
    bearings.


    52100 kabmob steel yog ib hom ntawm tshwj xeeb steel nrog nta ntawm
    lub siab coj kuj thiab dov qaug zog lub zog. High-carbon chromium
    kev coj tus kheej steel, engineering hlau thiab ib co hom stainless hlau thiab
    tshav kub resistant steel yog siv raws li cov ntaub ntawv ntawm bearings thiab lwm
    lub hom phiaj.

    Qhov zoo ntawm Chrome Kabmob Steel 52100:

    • Superior hardness, 60-67 rau Rockwell hardness scale (RC) nyob rau hauv chav tsev kub

    • High carbon chrome hlau steel

    • Ua hauj lwm tsis tu ncua ntawm kub txog li 120 ° C

    • Siv los tsim precision pob bearings thiab cov menyuam bearings

    • Nqi-zoo

    • Ntev ua hauj lwm lub neej
