My first expericence with inconel was many years ago and the company chemical division was trying to develop a new process to refine copper ore. That division asked us to expose the ore to high temperatures to bring about a chemical change. The material was placed into what looked like large baking pans. The pans were made of sheet inconel probably .050 thick. Once the pans, containing the ore were placed in a forge and brought up to several thousand degrees, the inconel pans were nearly white hot and you could see the ore material through the side of the pan. After a number of heating and cooling cycles like this the pans were warped, but there were no failures of the metal.

You need constant coolant flow when milling inconel at lower rpm with very specific inserts made for it, or you can get ceramic inserts which you _have_ to run at very high speeds, the chips come off glowing red. I've machined inconel parts weighing several tons (using a mill with 42 feet of X-axis travel, 13 feet on Y and seven feet on Z, not your average mill lol, the thing could turn a 12 inch face mill at a half inch depth of cut in steel), going through four grand worth of inserts in a day was normal operating costs which were actually very optimized. The stuff is universally hated by machinists, every time one of us knew an inconel part was coming down the line the bitchfest began, the stuff is awful. Also, you need carbide drills if you want to poke any kind of accurate or deep hole in inconel, HSS or M2 cobalt is just way too soft and not rigid enough, that's the awful chattering you're seeing/hearing. Straight flute gun drills with pass through coolant work the best. And when using any endmills, keep the flute length as short as physically possible and chucked up as close to the flute ends as possible, every micron of deflection you can prevent means a longer tool life. And use high helix endmills, they're absolutely necessary.

Doing it yourself saves a pittance of money (not time!), but any time we had to send some out to get work done to it, every single work order was 3-4x the price right off the bat. On the flip side, watching it shrug off afterburner exhaust as 'lowly' stainless begins to warp is quite rewarding.

Every spring pass would take out more material, due to tool deflection and wear of the insert, that is, until you work harden it. if that happens you’ll need to take a much deeper cut to get under the hardened layer, not easy when you’re working to +/-.001” with a 16 finish on £1/4million parts. There’s actually a few different grades of inconel, 718 was one of the worst to work with, so much so that 925 grade inconel felt like mild steel in comparison.

Inconel is a trademark that covers a big family of different alloys. It helps to be precise. There's a huge difference between an annealed inconel 625 and a precipitation hardened inconel 718. I'm guessing you had something like 718 which is why it behaved the way it did. If you can get it up to about 1000-1100C and hold it for a few hours, that should dissolve the precipitates so it softens to the point where you can work it.

I love that Martin is the "Teller" of this duo and Tim is the "Penn".

I worked in aerospace and we used inconel 718 all the time... It took a 120 ton forming press to mold that stuff into shape and our material was only 1/4" thick. We could not go from bar stock to final part, there was about 5 forming steps with different dies in the press. In between each step we had to send all the parts out for a heat treat. We manufactured the different compressor stages for the GE 90 Turbofan engine, the one used on the Boeing 777... So yeah it is a total pain in the ass LOL

I suggest doing a good amount of research before you mess with it in any major way to save yourself some cash and time. Edit: Also, as someone said before, coolant is absolutely required if you are trying to cut it with HSS, extremely recommended if you're cutting with carbide. Both of those cutter types will fail much more quickly without coolant when cutting inconel. Also, I dunno why you'd want to use inconel unless you're making a combustion chamber or certain other parts for a rocket or high performance jet engine. It's primary application is environments with extreme heat. It's not harder than the hardest types of steel, but it doesn't get softer with heat like steel until you get it VERY hot.

Well inconel is a nickel base alloy and it is alloyed with (mostly) chromium, molybdenum, vanadium, niobium, cobalt, manganese etc... Nickel and chrome (vanadium and molybdenum not so much but still) are the most important alloy elements for making steel resistant against corrosion and other properties a also achieved by adding these metals to iron alloys for example nickel is used in steel alloys for low temperatures (-50°C and lower) to prevent that the steel get to bridle in the real world that and similar alloys a used for almost any liquid gas application

I used to machine it years ago when I had a shop and made small Aerospace parts. It machines similiar to Titanium-Stainless alloys. Nice orange colour while it was in the forge! That power hammer is wonderful.

It is perfect for making tongs, mandrels and other tools that contact very hot metal very often

I worked in a machine shop in Houston back in the ‘80’s. We used a lot of inconel for the oil industry. I don’t know which particular alloy(s), but I remember picking up a bar about 1’ long and 3” diameter and it was insanely heavy.

Inconel is a nickel alloy. To cut it on a band saw you need to set your speed, feeds and drop to a minimum. Cut slow, feed high and drop slow. The settings we use is 19rpm speed, 8 feed and 0.5 drop. It takes a long time to cut so just be patient and it will cut. Oh and you need constant stream of coolent. If you try to cut this stuff without coolent you will just burn out your blades.

General Motors forged inconel for years at their locomotive division. It was used to make heads of diesel engine valves. The valve line at the plant was pretty impressive, I used to give tours of it. The line started with the inconel bar stock, which was cut into slugs of the proper length, heated by high-frequency induction until it was red-hot/glowing, and then forged into the rough shape of the valve head.

It's also used in extreme chemical environments where even the most corrosion resistant steels wouldn't last five minutes. It has great resistance to hydrogen sulfide for example, so it's very popular in the oil and gas industry in places with sour gas. It can be readily machined using the right tooling. It can certainly be forged too. You need to get your speeds and feed rates right too.

I worked 625 inconel in aerospace apps. One thing you find out is you can't hand drill with cobalt bits and fast drills. Once it snags...you have a shattered bit. We used hss bits and replaced them often. If you ran a bit until it dulled...it would work harden the hole instantly. So any heat buildup is bad news. You use a lot of bit lube (boelube) and slow rpm. that is probably what happened to your small end mill and drills.

I made a firearm safe and used Inconel sheet, dura plate 5 on 5 and 8mm SAF2205 in a laminated configuration and ran 30 kg of 6mm ball bearings in grout slurry between one of the lamination, then I ran a spring loaded glass relocker on the four sided 12 x 30mm stainless steel pins running off a four way gear driven locking mechanism all locked by a custom locking set up! Let’s just say I needed to hire a crane to get it home!! I would say thermic lance would be the only way in for undesirables!! Metals are crazy stuff to work with love em all!!!

I wonder if the folk over at the inconel foundry are having a chuckle

I used to build gas turbines in a previous life (industrial ones for running oil pumps, making power etc) and I've worked with inconel (and nimonic) a *lot* though I've never machined it myself. We used to have a robot that would take pre-cut blocks and mill them (with intricately hollow air channels inside and have super fine air holes drilled) into gas turbine blades all day and all night and then they'd be sent off for ceramic powder coating and the like - this was the very late 90's when basically nobody was doing that. We used to go watch it do that on like lunch break or whatever - but there would have been a time when people would have done that not totally unlike the way you're machining it here which is crazy to think. It's my understanding that with these superalloys you're supposed to essentially take out big lumps in one go with really powerful machines to get around the work-hardening problem.

I just want to say that you and your videographer do some really great work with lighting.

I would have felt bad but I would have laughed so hard if when you set it back 8n the press if it fell back into the hole.

I encountered several exotic alloys while I was in the relief valve business. Monel, inconel and hasteloy. I still have some that were discs from relief valves.

Welding it is always a trip haha if you don't follow the right process and preheat (usually) prepare for the cracks haha

I made a knife blade of a cold saw blade. I don't know what that metal is called but when it's cold it's extremely hard even without hardening. The way I drilled holes for wooden handle was to use a masonry drill bit and let it heat up to red hot and thereby drill through. No way you can drill it with ordinary metal drill and I believe even ordinary tungsten drill bits would be damaged. The masonry drill bit got red hot but appeared unharmed afterwards - not even slight wear and 100% still working properly.

We install splash plate inside of our plastic injection molds, on the opposite side of where the nozzle mates to the back of the mold. When the nozzle squirts plastic into the cavity, it hits that plate, and over a few 1000's cycles... the plate still shows wear... tough stuff..

Friction welding Inconel ? great video. What an amazing material.

I enjoy how you progressively try forging more difficult materials.

It's also super hard to weld with, at least with stick. We chew through bits like crazy with pneumatic bevelers on inco cladden boiler tubes. Sometimes we use inco for hardfacing boiler walls in high wear zones with $1,000 per roll mig wire. It's a beautiful material.

you can try milling or drilling down to the work hardened area then try reheating the piece to reset the temper in the material . it's not like copper were heating gets rid of work hardening but it may take some of the temper out and reset it you know it never hurts to try

Inconel has a high Nickel Content. Low RPM, Light cuts. I cut Inconel 600-900 pretty much daily. In a lathe there are special inserts that are designed to cut inconel. Inconel 718 is a Heat Resistant Super Alloy. Its a tough material to cut. But very rewarding.

This material is brutal. I've worked for a company, Tempress Netherlands, in the eighties that made furnaces for eletronic wafers, and in these machines they did heattreatments with special gases. To hold these gases in the spot they usef baffle plates which were hanging on wires that were fixed on the top of the furnace. All inner material was made of Inconel and the holes in the top plate, which was 5 mm thick, were 3 mm drilled holes. Every plate had maybe more than 100 holes. With one drillbit you could drill 3 to 5 holes. Untill I found out that if you aliviated, by grinding, the drill bit and leave just a small contact brhind the cutting edge, so that coolant could get very close to the edge, tha then I could drill up to 25 holes before sharpening the drillbit again. Yes it is a special material to work with.

Inconel is pretty brutal. We work with a lot of machine shops and while some are able to work with it, there are a lot of others who don't want to touch the stuff. It's just brutal on tooling

Inconel has been used to make exhaust valves in Top Fuel Drag applications.

It work hardens very easily and also hardens with age. When it comes to machining it you have to find the balance between slow and fast and all the coolant you can throw at it

We use this a lot at my work in the oil industry. It's is VERY EXPENSIVE and tough 💪💪

reminds me of the time I tried to forge some Monel tubing. Yeah, those alloys don't want to move. Lesson learned.

Has good chemical resistance also. amazing stuff.

I bet this stuff would be fantastic for a dross skimmer with molten metal. or as a set of crucible tongs. If its this heat resistant it should be usable in those applications for a very very long time.

I've been reading the comments and it's easy to tell who was taught the right way how to machine inconel and who wasn't

Inconel is fairly common in the high end valve industry. It is fun to machine ACME threads for a valve stem.

Congrats your a material scientist now you've just discovered that the molecules of inconel are ridged in extreme temp's

How would this work as a hot punch/drift?? Make one and try?

@@jarlove you can't.

My entire forges ducks nest and clinker breaker (weighs about 60#) is made from 3/8” incolnel I cut out at work lol. It’ll still be usable in 10,000 years. Remember that old Johnny cash song, “I got it one piece at a time…and it didn’t cost me a dime”

If it's work hardening while cutting you can probably increase the SFM and adjust feeds accordingly, you will also need running coolant to reduce the speed it's work hardening at. Have a look at speeds and feed charts for 316 stainless, then have a look on practical machinist and notice the difference in the advice. I only have experience with 316, but expect them to work very similarly.

Inconel X-750 was used on the X-15, the airframe that Pete Knight flew to Mach 6.7, over 4000 mph. It keeps its strength at high temperature. If forms a variety of crystaline structures based on different concentrations, though the matrix is Face centered cubic (like red hot iron) the various precipitates form tretragon or romboid crystals which block the slip planes.

The North American X-15 rocket plane had skin made from inconel (actually, Inconel X), as the skin reached over 1200C at speeds approaching (and exceeding on one flight) Mach 6.

I'm curious how well this would hold a sharp edge as a blade.

We had to machine some inconel for some heat and chemical resistant stuff at a shop I worked at years ago and it was like machining D2 only worse. As long as you are taking thick chips with a sharp tool with good cooling it's not too bad but as soon as you ease off the cutting pressure or the tool gets even a little dull it work hardens at the surface and it's a pain to get past that again. We found using new carbide tooling and committing to the cut once you start works well. Trying to go slow and easy on the tool was a recipe for broken tools.

I'm digging the midweek content. Keep up the awesome work

Looses piece of Inconel in hole under flypress. Proceeds to pull it out and throw it right beside the same hole

I am impressed how well it maintained hardness under heat.

Maaan, why is this man with his awesome videos, not getting enough views and subs? Really appreciate the content!

Cried with laughter the first time you hit that thing. How does it do on the lathe?

It work hardens like a bitch when machined. Eats through carbide cutters like butter after a short while.

These are my favorite videos that Tim does😄

Wander what kind of knife blade it would make.

@@Ltifone2014 lol.. You're backwards.. It would be very sharp-- but no so tough. It would be very brittle and break easy like glass. Maybe being used as an edge insert....... but I bet it would still break and chip easy.

We if you can read up on D6AC steel, very strong but very high maintenance. It was used a lot in F111 aircraft and very susceptible to scratches and corrosion turning into stress fractures.

The Camera work is awsome! Love the scene where the Inconel is heated in the Forge.

I am an aerospace machinist. Machining all of the high nickel superalloys sucks. They are what we call gummy, the material doesn't break a chip it just smudges out of the way then dulls the cutters. We actually do some very large parts for Blue origin that are 3D printed nickel alloy

I admit, I knew what was going to happen here... I just really wanted to see someone figure it out for the first time, lol. Inconel is a monster material!

Love these designer metal episodes. Have you tried forging different grades of titanium into billets for knife scales? Flame anodizing might be awesome. ✌

Titanium burns like magnesium. It really wants to be titanium oxide. That’s why it is welded in inert atmospheres.

Hey Timothy, long time viewer here. I’m a machinist and hobby blacksmith. If you ever want some info, tips, tricks on machining just let me know. Love your videos, super entertaining. Keep up the great work.

It’s very effective as a suppressor for high fire rate rifles

You should watch inconel suppressor failures. Some that I've seen will just explode like what happened to you. Very fascinating material
