How to Heat Treat 4140 Steel The Heat Treatment Furnace. The process of heat treating is a complicated one if you are hopingheat treatment of 4140 steel Quenching. Quenching is the rapid cooling of the metal. Tempering. Quenching makes steel very hard. It will also make it brittle. Annealing. The process of annealing heat treatment of 4140 steel
For spheroidizing annealing of 4140 alloy steel, it needs heat treated to 749 C (1380 F), followed by slowly cooling to 666 C (1230 F) at a rate of 6 C (10 F)/hour, or rapid cooling to 675 C for isothermal annealing.
Stormcrow, the steel used and the heat treat are somewhat shape dependent on power hammer dies. 1) 4140 is an OK die steel but is not recommended for radical shaped dies such as narrow fullering, crown and so on. 2) Fully hardened 4140 ranges from 54 to 59 HRC. But it should be tempered for any heavy use.

Heat Treatment. AISI 4140 alloy steel is heated at 845C (1550F) followed by quenching in oil. Before hardening, it can be normalized by heating it at 913C (1675F) for a long period of time, followed by air cooling. Forging. AISI 4140 alloy steel is forged at 926 to 1205C (1700 to 2200F) Hot Working. AISI 4140 alloy steel can be hot worked at 816 to 1038C (1500 to 1900F) Cold Working. AISI 4140 alloy steel can be cold worked using conventional methods in the annealed condition heat treatment of 4140 steel
4140 is not used for carburizing, but it can be surface hardened using induction. Based on the feedback that you received, it sounds like your heat treater was describing the problem of 4140 and carburizing. If you want the part carburized to your spec, then the suggestion of 8620 by arunmrao is a good one. If you want the part induction heat treatment of 4140 steel

Interested in some information on heat treat for 4140 for hand forged cleavers, hatchets, and shop tools. Not much luck so far searching, also wondering if thereis a thread with consolidated heat treatment "best practices" that I am missing.
Heat Treating Overview Heat treating, as the name implies, is a series of treatments in which heat is used to alter the properties of a metal or alloy. Because time at temperature is also important, heat treatment can be further defined as a series of time-temperature treat-ments. Heat treatments are used for a variety of purposes, the
Heat Treating Data Book Tenth Edition E-Book Published by SECO/Warwick Corporation 180 Mercer St., PO Box 908, Meadville, PA 16335 USA www.secowarwick.com SECO/WARWICK Corp. is a member of the SECO/WARWICK Group (SWG) of companies The SECO/WARWICK Heat Treating Data Book contains information about heat treating metals.
4140 steel is medium hardenability steel with good strength and good comprehensive mechanical properties after heat treatment. It has good manufacturability. The maximum temperature of use is 427 C. It can be used to make turbine fastener, tool bodies, forming dies, brake dies and etc.
See Heat Treating 4140 Hammer Dies Includes temper table. Annealing is the softening of metal by heat treatment. Ferrous metals are annealed by heating to just above the A3 point (a point above non-magnetic that varies with the carbon content), and then cooling slowly.
Heat Treatment Guide. The chart below describes various types of tool steels, their composition and appropriate heat treating applications.
4140 HIGH TENSILE STEEL 4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).4140 is now available with improved
Predicting Size Change from Heat Treatment Last updated on 8/26/2019 While a precise forecast of a steel parts size change during heat treating cannot be expected, by considering potential factors, a heat treater can provide a reasonable estimate that can help the shop prepare for final machining operations.

BCIT millwright students heat 4140 steel to 1650 Deg F to heat treat and harden. The process show the quenching in oil. Be sure to use safety gear when doing this type of work for personal safety.
Chapter 2: Fundamentals of the Heat Treating of Steel / 11 Steel, however, is by far the most widely used alloy and for averygood reason. Among layman, the reason for steels dominance is usually con-sidered to be the abundance of iron ore (iron is the principal ingredient in all steels) and/or the ease by which it can be rened from ore heat treatment of 4140 steel
A2 Tool Steel. A2 Tool Steel is a versatile, air-hardening tool steel that is characterized by good toughness and excellent dimensional stability in heat treatment.A2 is intermediate in wear resistance between O1 oil-hardening tool steel and D2 high-carbon, high-chromium tool steel.
Heat treating, or heat treatment, is a controlled process that is used to alter the physical and chemical properties of metals and alloys such as steel and aluminum. This method of finishing increases surface hardness, ductility, and strength.
I heat treated a piece of, what I thought was, A-6 tool steel. The piece did not machine like tool steel but I have never worked with A-6 tool steel. Now I think the piece was actually 4140 because after tempering at 600 deg, the piece lost most but not all of the hardness.
My steel yard has volumes of 4150 tool steel in a usable size. I typically use spring steel or 4140 for making top & bottom tools, tongs, and hammers. My question is, can I exchange 4140 for 4150? If so, what is the difference in the two metals. Im guessing 4150 has more carbon and would requheat treatment of 4140 steel
AISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of heat treatment of 4140 steel
D2 Tool Steel is a versatile high-carbon, high-chromium, air-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials.
