Atlas 8620H can be carburised and subsequently hardened by a quenching and tempering operation. The8620 Gear Rack Case hardening Practical MachinistNov 17, 2016· 8620 is a gear material that is used throughout the industry. The 20 in 8620 means that the steel contains 0.2% carbon. This low of a carbon content means the material will not respond to heat treat. The work around is carburizing. The steel is soaked at ~1450 degrees F for many hours in a carbon rich environment.
Hardening steel with motor oil is a way of performing what is called the case hardening of steel. Pure steel is actually too soft for many applications. In order to put a hard layer on the steel, carbon must be fused at the molecular level into the top centimeter or so of the steel. One way to do this is to make the Alloy Steel 8620 All Metals & Forge GroupAlloy Steel 8620 Principal Design Features. AISI 8620 is a hardenable chromium, molybdenum, nickel low alloy steel often used for carburizing to develop a case hardened part. This case hardening will result in good wear characteristics. Applications. In the carburized condition this alloy is used for gears, ring gears, shafts and crankshafts AISI 8620 Round Bar Case Hardening Steel Stockist AISI 8620 is a Hardenable Chromium, Molybdenum, Nickel Low Alloy Steel often used for carburizing to develop a case hardened part. This case hardening will result in good wear characteristics. 8620 is commonly used in the engineering and automotive industries for tool holders and other such components.
The general characteristics of AISI Alloy Steel 8620. AISI Alloy steel 8620 is a case hardening steel containing chromium, nickel and molybdenum as alloying elements. The following given table below shows the chemical composition of AISI 8620 alloy steel.8620 Case hardening steel8620 Case hardening steel Typical Analysis C Si Mn Ni Cr Mo (Ave. values %) 0.20 0.25 0.8 0.50 0.50 0.20 BS SAE NEAREST STANDARD EN 362 8620H DESCRIPTION 8620 is a balanced low nickel/chromium and molybdenum general purpose case hardening steel, suitable for comparatively light stressed components. APPLICATIONSCase Hardening Steel SAE 8620 Case Hardening Steel SAE 8620 is a case hardening steel with low carbon content but good hardenability reaching good wear resistance due to high surface hardness after hardening. The small grain size benefits in good ductility and fatigue strength. This combination of properties provides wear resistance and fatigue strength at the surface, and impact strength in the core.
8620 steel suppliers, delivering to the whole of the UK. This grade is a low alloy nickel, chromium, molybdenum case hardening steel. Carburised 8620 gives a hard case with a strong core whilst retaining a remarkable degree of toughness. SAE 8620 is suited for applications which require a combination of toughness and wear resistance.Atlas 8620H Case Hardening Steel Bar 8620HCase Hardening Steel Bar 8620H Colour codeRed (Band) White Introduction Atlas 8620H is a low Nickel Chromium Molybdenum case hardening steel of medium hardenability used principally for relatively lightly stressed components. Atlas 8620H can be carburised and subsequently hardened by a quenching and tempering operation. TheCrucible Selector AISI 8620The hardening treatment is selected in accordance with the case and core properties required for the particular application. Although there are many hardening treatments for carburized grades, the treatments shown are typical of some that are frequently used. The usual carburizing temperature for AISI 8620 is 1650 1700F (900 925C).

Oct 07, 2019· 0.25 percent. A36 is a low carbon or mild steel, and as such cannot be hardened. It can be case hardened, however, which just means using a chemical treatment with heat to add a thin layer of tough material around the soft steel core.Heat Treating & Hardening 4140 Steel Material Jun 30, 2006· I chose 4140 steel to be machined and hardened, RC 56 62 to a depth of 0.030 0.060 to achieve high strength components. I was just told that hardening 4140 will achieve a thru hardening instead of case hardening.Process of Case Hardening Steel & MetalsWhat is Case Case hardening is a heat treatment technique in which the steel surface is processed by the addition of carbon. Case hardening of steel is used for numerous applications including for the manufacture of carbon steel forgings and carbon steel pinions. Alloy steels are normally case hardened to increase the metal characteristics. The outer layer of case hardening steel becomes hard, while the
