    ASTM A295
    is specification which covers 52100 high carbon bearing quality steel
    to be used in the manufacture of anti-friction bearings. And 52100 bearing steel is the most common steel grade in ASTM A295 standard for high-carbon anti-friction bearing steel.

    What is 52100 bearing steel?

    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 (Rc) 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

    4. 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 anneale, 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.

    5. 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.
