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
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
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
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.
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
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.
(910ºC) and air cool. This is another method of improving machinability
in 8620 material; normalizing might also be used prior to case
7. Machinability of SAE 8620 Steel
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
8. Welding of 8620 Materials
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
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.
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
