    Property 8620 vs 8620H

    As 8620 steel material could be case hardened, so the hardness could be different after hardening. AISI 8620 can be supplied in “H” condition with required hardenability. Strict analytical limits provide controlled response from heat to heat, making it an ideal selection for production case hardened parts, where consistency in heat treatment is required. AISI 8620 is usually further normalized or Quenching and Tempering and supplied as AISI 8620H.

    SAE 8620 Grade Application:
    The SAE 8620 can be used for a number of medium-strength applications such as camshafts, fasteners, gears, and chains/chain pins.

    SAE 8620 Heat treatment:
    This alloy may be hardened by heating to 1500 F followed by a water quench. Carburize at 1650 to 1700 F in an appropriate carburizing medium and oil quench to harden. Improved carburized case and core properties can be obtained by furnace cooling from carburizing at 1650 – 1700 F and then reheating to 1575 F.
    SAE 8620 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.
    SAE 8620 Tempering:
    Tempering of heat-treated and water quenched parts of SAE 8620 steel (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.
    SAE 8620 Physical Properties:
    The physical properties of SAE 8620 alloy steel are highlighted in the following table.

    323 BTU in/hr.ft².°F
    SAE 8620 Forging Properties:
    SAE 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.
    SAE 8620 Stress Relieving:
    Heat to 630°C – 650°C, hold until temperature is uniform throughout the section, soak for 1 hour per 25mm section, and cool in still air.
    SAE 8620 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.
    SAE 8620 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 the furnace or air-cooled.
    SAE 8620 Density:
    Density (lb / cu. in.) 0.283
    SAE 8620 Machinability:
    The SAE 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.
    SAE 8620 Welding:
    The alloy SAE 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.
