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.

F-OLB20 Olympic Lifting Bar – Men’s Bar 20kg – Crossfit Bar from Force United states of america
Introduced by Phil Eton of Heartbreak Conditioning.
www.heartbreakconditioning.com
Force United states of america Olympic Lifting Bars (F-OLB10, F-OLB15 & F-OLB20) are all lined by the Force United states of america Life span STRUCTURAL Guarantee. This is the only range of bars rated and warranted for Crossfit use in Australia.
Utilizing the most recent in Crossfit engineering, the ends spin like a needle bearing bar but with out all the challenges of needle bearing bars when made use of in Crossfit these types of as popping and breaking.
Extensive study and improvement has led to the improvement of this elite bar, the greatest in engineering for Crossfit and Olympic Ability Lifting. Usually olympic bars are warmth treated S45C with a tensile strength PSI rating of 119,900 PSI. The F-OLB range of Force United states of america – Olympic Lifting Bars are warmth treated SCM440 with a tensile strength PSI rating of 216,000 PSI. All a few models have been in household fall tested up to 30,000 times and the sleeves have been undamaged and continued to rotate beautifully. Each and every bar has been precision milled to actual pounds and duration specification with a tolerance of +two%/-%.
The stand out attribute of the F-OLB Force United states of america – Olympic Lifting Bar range is the design and style construction. F-OLB20 (Men’s bar) is produced with Molybdenum-Chromium Alloy Metal and the F-OLB10 (Training bar) and F-OLB15 (Women’s bar) are produced with Weighty Responsibility Carbon Metal. The special ‘Control Ring’ design and style is a innovative patented locking method. The knurling on these bars has to be felt to be believed. From your 1st grip, no other bar will feel the exact same yet again. The bars are finished with black oxide and really hard chrome.
