Case-hardening steel 20NiCrMo2-2, 1.6523, AISI 8620, 805M20 for heavy duty parts of machines and vehicles according to and EN 10084. 8620 Bar & Tube - Sullivan Steel ServiceGrade 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 (good strength and toughness properties). Machining is done prior to carburizing to within as close a tolerance as possible. Finish machining or grinding after heat treatment and/or Read more about 8620
8620 is a low nickel - chromium - molybdenum medium hardenability, case hardening (carburizing) steel, generally supplied in the as rolled condition with a maximum brinell hardness of 280 (Rc30).Characterised by good core strength and 8620 Gear Rack Case hardening - Practical MachinistNov 21, 2016 · Is there a super important reason to use a case hardening steel instead of just through hardening a bit of A-2, D-2, or S-7 (or even 4140 if the cost of toolsteel is an issue) and wirecutting the teeth after hardening? You'll likely get a much more predictable rack for AISI 8620 Steel 1.6523 21NiCrMo2 SNCM220 - Otai AISI 8620 Steel is a low alloy nickel, chromium, molybdenum case hardening steel. We supply Schlumberger good quality sae 8620 round bar.
8620 is a low nickel chromium molybdenum medium hardenability, case hardening (carburizing) steel, generally supplied in the as rolled condition with a maximum brinell hardness of 280 (Rc30).Characterised by good core strength and toughness in small to medium sections with case hardness up to Rc62 when carburized, hardened and tempered.8620 can also be used (uncarburised) AISI SAE 8620 Steel Properties, Chemical Composition AISI SAE 8620 Steel (UNS G86200) AISI SAE 8620 steel is a commonly used low-alloy material for carburizing, with excellent carburizing response, good hardenability for most section sizes, it has many extensive applications due to its low cost, better machinability, and availability.

We are offering a wide range of SAE 8620 Steel Round Bars.It is a low alloy case hardening steel which is supplied to American standards SAE 8620 and AISI 8620. 8620 can be carburized, which will achieve a tough core with a hard wear resistant case. 8620 provides a combination of toughness and wear resistance. 8620 is supplied in either the as rolled or annealed condition for subsequent case Case Hardening Steel bar - SAE 8620 Case Hardening Manufacturer of Case Hardening Steel bar - SAE 8620 Case Hardening Round Bar, EN 36 Rod, EN 31 Round Bar and Case Hardening Steel offered by Devasya Industries, Sanand, Gujarat. Crucible Selector -AISI 8620The usual carburizing temperature for AISI 8620 is 1650-1700F (900-925C). Uniform temperatures must be provided to produce uniform carburizing and hardening and to control distortion. It is important the temperature of the steel be maintained rather than just furnace temperature. 1. Quench Directly From Carburizing Box.
Oct 16, 2012 · This work was expanded to examine the fatigue properties of specimens carburized to a specific case depth, and to compare them with the properties developed through separate heat treatments simulating case and core. SAE 8620 was selected and two sets of specimens were heat treated to simulate case and core respectively, as described above. Heat Treating Camshafts Metlab Heat TreatMar 15, 2011 · These camshafts are manufactured from 8620 or 9310 steel, range in size from 1 1/2 3 1/2 O.D. x 24 to 72 long. The heat treating is done with the parts in the vertical position, resulting in a product which is straight within 0.005 T.I.R. Heat treatment requirements are a case depth of 0.120 minimum, and surface hardness How to Harden Steel With Motor Oil SciencingHardening 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
Aug 10, 2005 · The part is 16"OD 5"ID 1.1"thick 8620 steel. After case-hardening 54-58Rc .040"total deep, the pitch dia. of the spline grows .020"-.040" on different parts in the same heat. Is this to be expected? RE:Inconsistant dimensional growth after case-hardening 8620 Inconsistant dimensional growth after case-hardening 8620 Aug 10, 2005 · spline teeth. The part is 16"OD 5"ID 1.1"thick 8620 steel. After case-hardening 54-58Rc.040"total deep, the pitch dia. of the spline grows.020"-.040" on different parts in the same heat. Make Sure Your Specified Heat Treatment is Achievable Benability of the steel chosen can be narrowed by either using an H steel or using a restricted harden-ability specification of an H steel. The effect on hardenability of an 8620 steel having a specified chemical composition versus 8620H is shown in Fig. 3. The effect of
SAE 8620 can be used as an alternative to more costly alloyed case hardening steels. Grade 16MNCR5 and 20MNCR5 steels are case hardening steels used extensively for both carburising and carbonitriding, demonstrating reasonably high hardenability and excellent forgeability. It has become an accepted alternative to SAE 8620 in some cases. Encore Metals - 8620Grade 8620 is typically available Hot Rolled, As Rolled. Larger diameters are Hot Forged, As Forged.
