AISI 8620 SAE 8620 Alloy Steel Round Bar1: 8620 steel
introductionAISI 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 . 2: 8620 Steel

4: 8620 steel mechanical properties The
mechanical properties mainly include tensile strength, yield
strength, elongation, area or reduction, hardness, impact value,
non-metalic inclusion etc. Different heat treatment, the mechanical
properties will be different, such as normalized, tempered, QT. If
you want to know the properties, kindly contact the salesman. 5:

for 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.6: Delivery conditionFor hot
forged bar, usually the delivery condition is hot
forged, annealed/QT, rough turned/Black surface. For hot rolled
bar, usually the delivery condition is hot rolled, annealed/QT,
Black surface. Hunan Qilu Industrial Co., Ltd has the capacity to
forge round steel, steel flat, square steel, module, shaft and
roller, etc. The main specifications of the products include
Φ80-1000mm forging materials and 80-1200mm square billets and which
the maximum piece weight can reach 50T. Hunan Qilu Industrial Co.,
Ltd were already engaged in exporting steel for 11 years,
could supply a great variety of hot forged, hot
rolled and cold drawn Steels, including
engineering steel, cold work tool steel, hot work tool steel,
plastic mold steel, spring steel, high speed steel, stainless steel
etc., besides Qilu Industrial also has their own heating treatment
shop and machining shop to provide heating and cutting service.
Since 2008 year, Hunan Qilu Industrial has the right to export
all FORGED STEEL behalf of Qilu Speical Steel Co.,ltd
