    AISI 52100 Cold Drawn Hardened Alloy Steel Round Bar High Mechanical For Bearing

    AISI/ASTM 52100 bearing steel is a high carbon, chromium containing low alloy steel that is through hardening and noted in particular for use as bearings.

    52100 bearing steel is one kind of special steel with features of high wear resistance and rolling fatigue strength. High-carbon chromium bearing steel, engineering steel and some types of stainless steel and heat resistant steel are used as materials of bearings and for other purposes.

    Advantages of Chrome Bearing Steel 52100:
    Superior hardness, 60-67 on Rockwell hardness scale at room temperature
    High carbon chrome alloy steel
    Operates continually at temperatures up to 120°C
    Used to produce precision ball bearings and roller bearings
    Cost-effective
    Long working life

    5. Forging of A295 52100 Bearing Steel
    AISI 52100 alloy steel is forged at 927 to 1205°C, and should not be forged below 925ºC. A post-forge equalization treatment is recommended at 745ºC for 4-6 hours followed by air cooling for SAE/AISI 52100 steel.

    6. Heat Treatment for ASTM 52100 Bearing Steel
    ASTM/AISI 52100 alloy bearing steel is heated at 816°C followed by quenching in oil. Before performing this process, it is subjected to normalizing heat treatment at 872°C followed by slowly cooling in order to reduce the machining stress.

    Hot Working
    AISI 52100 bearing steels alloy can be hot worked at 205 to 538°C.

    Cold Working
    AISI 52100 bearing steel can be cold worked using conventional techniques in the annealed or normalized conditions.

    Annealing
    For spheroidize annealing, the following isothermal anneal is recommended:

    1500ºF (815ºC) for 3 hours
    1350ºF (735ºC) for 4 hours
    1250ºF (675ºC) for 3 hours
    Slow cool to 1000ºF (540ºC) then air cool.

    Quenching
    AISI 52100 alloy bearing steel could be hardened by quenching in water from 801-829 degree or quench in oil from 816-842 degree.

    Tempering
    Temper to desired hardness as indicated by tempering curves after water or oil quench.

    7. Applications of 52100 Bearing Steel
    Alloy steel 52100 grade bearing steel is mainly used for the manufacture of aircraft bearings and other highly stressed parts. This steel grade 52100 steel is preferably vacuum arc re-melted to give optimum performance.

    Typical applications: Bearing Manufacture, CV joints, ball screws, gauges, knife etc.
