heat treating 52100 KnifeDogs Forums

Oct 13, 2012 · hi, bought a piece of 52100 from Aldo to use. went online to find some heat treat numbers. found some interesting articles. one looked at different alloys, 52100 vs 440c vs cpm9v. Recommended Working Sequence For 52100 - CashenbladesRecommended Working Sequence For 52100 . Forging:Heat to 2100 °F (1150 °C) maximum, and do not forge after temperature of the forging stock has dropped below approximately 1700 °F (925 °C) Normalizing:Heat to 1625 °F (885 °C) and cool in still air. Crucible Selector -AISI 52100High Heat:1500-1550F (815-845C), soak 10 to 30 minutes. For vacuum or oil hardening, use the high side of the high heat range and soak times. Use the low side of the temperature range for water hardening. Quench:Oil or water quench to hand warm, 150F (65C). Temper immediately. 52100 Heat Treat - Metallurgy and other enigmas Feb 18, 2014 · 52100 can be finicky. You really need a controlled oven to get consistently good results with it. If I had an oven to heat treat in, I would normalize one time each at 1600°, 1500° and 1300° to refine the grain and carbides. hardening 52100 - Heat Treating Knives, Blades etc - I Feb 22, 2011 · In 1966, the typical percentage analysis of E 52100 was:Carbon .95 - 1.10 Manganese .25 - .45 Silicon .20 - .35 Chromium 1.30 - 1.60 * "Heat Treatment and Properties of Iron and Steel", National Bureau of Standards Monograph 88, U.S. Government Printing Office, 1966. Carbide refining heat treatments for 52100 bearing steel The life of through-hardened 52100 anti-friction bearing components is improved if the excess carbides, undissolved during austenitization, are small and uniformly dispersed. One kind of carbide-refining heat treatment consists of 1) dissolving all carbides, 2) isothermally transforming the austenite to pearlite or bainite, and 3) austenitizing, quenching and tempering in the usual manner Properties of 52100 annealed condition?May 16, 2021 · I need to make some small thrust washers for a diff repair, I can heat treat if required. The question came up in regards to the strength and performance of 52100 in the annealed state. I have searched and searched but only found info on how the steel performs after heat treat. How to Heat Treat 5160 - Optimizing Toughness - Knife Apr 01, 2019 · Summary and Conclusions. 5160 has very good toughness with a heat treatment using an austenitizing temperature of 1500-1525°F and tempered at 375-400°F. That results in 58.5-59.5 Rc and very high toughness when heat treated with a cryo step. Skipping cryo may improve toughness slightly with a drop in hardness but this was not tested. blade steel:1095 or 52100 ?? Bushcraft USA ForumsJan 04, 2017 · I haven't used the 52100. I make all my knives from 1095 and like the way it grinds and finishes. I also like that the heat treat is relatively simple and I can do it my own shop without sending it out for final heat treat. I think that for the price 1095 can't be beat and it is a proven steel. Many major knife companies use it as well. Bearing Austenitizing and TemperingThe heat treatment of 52100 bearing steel must be controlled to produce a level of retained austenite that the bearing can tolerate in service. This often is considered to be <10% for most applications (nonstabilized) and <3% (stabilized) for superprecision applications. The graph shows that austenitizing temperature and tempering Petersen Knives » Heat TreatingThis is a 52100 blade heat treated using a rapid cycle quench technique using a reducing austenitic temperature sequence of 1575, 1550 and a final quench at 1525 F with a hold of 10 minutes on the first cycle and then two minutes on each sequential hold. The blade was quenched in a low temperature salt on the first two quenches in the cycle and
