    AISI 8620 Steel

    is a low alloy nickel, chromium, molybdenum case hardening steel,
    generally supplied in the as rolled condition with a maximum hardness HB

    255max. SAE steel 8620 offers high external strength and good internal
    strength, making it highly wear resistant. AISI 8620 steel has a higher
    core strength than grades 8615 and 8617.

    SAE 8620 alloy steel is
    flexible during hardening treatments, thus enabling improvement of
    case/core properties. Pre hardened and tempered (uncarburized) 8620 can
    be further surface hardened by nitriding but will not respond
    satisfactorily to flame or induction hardening due to its low carbon
    content.

    Steel 8620 is suited for applications which require a
    combination of toughness and wear resistance. This grade is commonly
    supplied in round bar.

    5. Forging of Material 8620 Steel

    AISI

    8620 alloy steel is forged at a start temperature of around 2250ºF
    (1230ºC) down to approximately 1700ºF(925ºC.) prior to the hardening
    heat treatment or carburizing. The alloy is air cooled after forging.

    6. ASTM 8620 Steel Heat Treatment

    • Annealing

    AISI

    8620 steel may be given a full anneal by heat to 820℃ – 850℃, and hold
    until temperature is uniform throughout the section and cool in furnace
    or air cooled.

    • Tempering

    Tempering

    of heat treated and water quenched parts of 8620 steels (not
    carburized) is done at 400 F to 1300 F to improve case toughness with
    minimal effect on its hardness. This will also reduce the possibility of

    grinding cracks.

    • Hardening

    The

    AISI steel 8620 will be austenitized at around 840°C – 870°C, and oil
    or water quenched depending upon section size and intricacy. Cool in Air

    or Oil required.

    • Normalizing

    1675ºF

    (910ºC) and air cool. This is another method of improving machinability

    in 8620 material; normalizing might also be used prior to case
    hardening.

    7. Machinability of SAE 8620 Steel

    The

    8620 alloy steel is readily machined after heat treatment and/or
    carburizing, should be at a minimum so as not to impair the hardened
    case of the part. Machining may be done by conventional means prior to
    heat treatment – after carburizing machining is usually limited to
    grinding.

    8. Welding of 8620 Materials

    The
    alloy 8620 may be welded as rolled condition by conventional methods,
    usually gas or arc welding. Preheating at 400 F is beneficial and
    subsequent heating after welding is recommended – consult the approved
    weld procedure for the method used. However, welding in the case
    hardened or through hardened condition is not recommended

    9. Application of ASTM 8620 Steel

    AISI

    8620 steel material is used extensively by all industry sectors for
    light to medium stressed components and shafts requiring high surface
    wear resistance with reasonable core strength and impact properties.

    Typical

    applications are: Arbors, Bearings, Bushings, Cam Shafts, Differential
    Pinions, Guide Pins, King Pins, Pistons Pins, Gears, Splined Shafts,
    Ratchets, Sleeves and other applications where it is helpful to have a
    steel that can be readily machined and carburized to controlled case
    depths.
