With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Heat tends to even out. If you try to heat treat steel without something to keep the heat in, it will be very difficult to maintain a temperature, and a lot of the heat will get wasted. That is why we will build a furnace chamber out of bricks. Try and find bricks that are rated for the highest heat resistance. Lay out a layer of bricks flat best 4140 heat treat
optimum heat-treat response in heavier cross-sections. You find 4140HW in a variety of bar and tubing applications in quenched and tempered conditions. Yield strengths range from 110 ksi through 140 ksi, but we can temper it to other strength levels. When compared with standard 4140 heat treated to
I usually send my heat treating out, but in the little bit I have done with a few types of steel, I think W1 drill rod is the easiest. Heat 'er up as fast as you can, and stick it in the cold water quench. However, I don't think that heat technique works quite as well for 4140, because it is slower to make the phase changes.

4140 Power Hammer Dies: I asked this question over on iforgeiron and was surprised with the answer, so I wanted to double check. I'm ready to heat treat the main flat dies for my homebrewed power hammer. The ram weight is 88 lbs, and the dies are 3" square 4140.
I am an 07/02 and working on a repair to a glock select fire conversion. The sear trip has been made out of 4140 and I am looking for heat treat info. 4140 may not be the best steel for this part, but that's what I had. I don't have an oven so this would be a torch heat and quench. Any suggestions best 4140 heat treat
SAE AISI 4140 Alloy Steel. SAE 4140 (AISI 4140 steel) is a Cr-Mo series (Chrome molybdenum series) low alloy steel, this material has high strength and hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperature.
4140 is .38-.43% carbon .8-1.1% chromium if your bar has .38% carbon and .8 Chromium and mine has .43 and 1.1 they are both 4140 and we heat treat them the same we will likely get different results. The expensive dies that I will be getting heat treated are going to be 4340 so i can get them harder in the heavy sections they will be.

The SECO/WARWICK Heat Treating Data Book contains information about heat treating metals. This book is not intended as a text, but rather as a collection of frequently used reference data to serve persons interested in heat treating technology. If it saves you time, we feel it will have accomplished its purpose.
The maximum hardness that can be obtained in any steel depends on carbon content. The section size in which maximum hardness can be obtained depends on alloy content. 4140 has a nominal carbon content of .4% and this carbon content will yield a hardness of Rc 51 for a 90% martensitic structure (9th Edition of the ASM Material Handbook,Volume I).
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 best 4140 heat treat

It is a bit unsatisfactory to call an alloy "4140 heat treat" since - quench and tempered - annealed - quenched but not tempered are all "heat treatments". So a name like "4140 heat treat" leaves me a bit doubtful about what I am getting for my money. So my questions are, a. What is the proper designation for the machinable version of heat best 4140 heat treat
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.
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.
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.

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 requbest 4140 heat treat
4140 = easy to machine but not the best material to use if you are welding to it 4130 = easy to weld to machining is not difficult 4340 = harder materail to machine. best if used for bolt on parts and if you are not going to heat treat the 4140/ 4130 part use this material any other pointers for use material challenged people?

I wasnt sure if there were any suggestion as how to accomplish this. Also there is a possibility that the 4140 is HT, it says it requires post weld heat treat but the 514 has a disclaimer on the cert. that recommends against any post weld heat treat. Thoughts?
General characteristics of 4140 Alloy Steel. AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. Its chemical composition is as follows. AISI/SAE 4140 grade is a versatile alloy with good atmospheric corrosion resistance and reasonable strength.
It all makes sense now. 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. Tempering 4140 at 600 deg makes 4140 49 RC.
4140 Heat Treated is a chromium-molybendium alloy steel. 4140 HT is the most commonly used high tensile steel with endless applications including everything from gears and pumps to various applications in the automotive and construction industry. 4140 HT has a medium hardness of 28/32 HRC.
4140 Hot Rolled Heat Treated Round Bar. 4140 is a widely used medium carbon steel. A general purpose alloy, has good strength, toughness and hardness. Refered to as chromoly steel, due to the inclusion of .95% chromium and .20% molybdenum alloying elements. 4140 Hot Rolled Heat Treated Round Bar
Another tid bit. We've used vacuum heat treat on 4140-4340 in the past and although we had a little less distortionbest 4140 heat treat the gas quench couldn't strip the heat out of the material quickly enough to get the hardness up at the initial quench like good old oil can. Meaning I doubt you'll achieve 44 RC surface on 5 inch diameter in a vacuum furnace.
Heat Treating a 4140 axle shaft. A discussion started in 2004 but continuing through 2017. 2004. Q. Hi. I am a college student living in Alaska, where we don't have trouble heat treating most steels in air. ;) Just kidding. I've taken metallurgy in college and have studied it on the side for a few months now.
Got a 4"x4''x12" piece of 4140 coming and will be making a post anvil out of it. What's the best way to heat treat? I've had good luck with spring fullers and such simply heating to critical and quenching in water. I'm thinking heat the end in the gas forge, say about 4-6 inches to critical and dunk in a bucket of water.
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 machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties.
Heat the steel to 1,675 degrees Fahrenheit in a heat treat furnace or forge and hold it at that temperature for approximately 30 minutes per inch of length to normalize the steel. Normalizing removes any stresses within the steel that could create cracks when hardened.
