One tip. Don´t use graphite together with steel. Steel and carbon can alloy, so the molten steel will eat away at the graphite and destroy the mould, while at the same time the steel will alloy with the carbon and turn into cast iron. For the same reason you shouldn´t use diamond cutting and grinding tools with iron and steel, because its going to quickly destroy the tool as the diamond is basically ripped apart on a molecular level by the iron.
Probably the most interesting thing about chemistry is that you need to be careful about what you use to hold the materials since the wrong container could have a reaction with the chemicals.
You will also get more control of the final alloy by excluding oxygen. In steel manufacture you have a reducing atmosphere. In this case probably the easist way would be to do it in a nitrogen atmosphere from a bottle. Though steel nails aren't usually the nicest steel to start with.
One thing I will add for anyone wanting to try this is avoid galvanized steel. Unless you're performing it outside or indoors with proper ventilation, zinc fumes can be very unhealthy to breathe in.
FYI, a lot of screws and nails and such are galvanised, that means as it burns it'll release toxic smoke. You don't want to breathe that stuff in. So if you gonna do this stuff, do it under a fume hood, wear a respirator, etc.
I always appreciate Nile Red's nonchalant way of describing what he's doing. He could have just as easily started this video with "I was walking through my neighborhood and came across an inductive furnace that someone had thrown out, so I decided to see if I could melt nails with it." and I don't think I would have batted an eye at it.
I also like that he doesn’t insult anyone’s intelligence by saying “please do not try this at home”. If you can’t figure out this is dangerous then that’s on you. He does his experiment and he ends the video. Informative AND hilarious.
Have have to phrase it correctly: ‘I was just walking through the neighbourhood and I saw this furnace so I thought I would just use it. So I just gathered some nails put it on. All I had to do was just put it on and wait.’ 😂😂
A tip if you ever want to melt/heat more Iron/Steel in the future. Once Iron (and Steel) get hot enough, they start shooting out UV rays in order to release the amount of energy they have. Looking at molten Iron can have the same effect as looking at the sun, albeit to a lesser degree. It is still a good idea to use eye protection that is tinted properly to deal with UV rays when metal working with Iron or Steel.
Hey mighty professor wilhelm... how much UV radiation is here? I can tell you: It is pretty much zero. It needs to be at least twice as hot that UV becomes an issue. The pain is IR here. So if you call yourself "Professor" and say anything about this topic: At least you should have paid attention to physics classes.
Wow. Not with that attitude. All the guy did was put some nails into a foundry and melt them. Pretty easy to do, and I am sure both of you are more than capable.
Then you're clearly new to his channel. I could definitely see him doing that, in fact, I feel like he might have done it off camera when we weren't looking.
I don't think anyone else is pointing this out, so I'll mention: most nails you buy at the hardware store aren't pure steel. Alloys aside, a lot of them have different coatings, even the ones that appear to just be regular steel with a shiny finish. The black ones are typically oil-treated or may even have an enamel coat, and the matte-gray ones have been Hot-Dip Galvanized in molten zinc.
Wear shade 5 to shade 8 welding goggles, preferably rose colored, for best vision, to protect your vision from high intensity light and to protect your corneas from thermal and UV burns.
@LordWaldemar yes. It's a full-spectrum black-body electromagnetic emissions source, but yes, you are correct: it's mostly IR. There is enough UV radiation to be a concern if you're melting metal frequently; for non-ferrous metals, I'd always wear good UV-rated sunglasses. For iron or steel, or larger brass melting, I'd wear welding goggles though. Even if I was just welding with a torch, or using a plasma arc cutter, you could still get "sun burn" just from the tiny flame.

It looks exactly like sparklers, because iron is the sparkly ingredient in sparklers. the base is some mix of coal and potassium nitrate for a strong steady flame and flakes of iron that burn and shoot out from the flame make up a show
This is the first time I’ve actually seen someone make steel on a small scale, as most of the time it’s just people melting things like aluminium or copper
Making steel from scratch on a small scale is easier than you might think, and with very little technology. In an iron bloomery, iron ore is oxidized beforehand and reduced in the furnace, allowing the iron to congeal without needing to hit melting temperatures.

The color changing is always so awesome. There you can tell how hot the steel is, 200-240c is yellow, then comes little bit red, then violet at 280c and then blue at 290c. If you'd stop heating at that point, they would retain their color, but it's only surface-deep unfortunately. You can even do that in a household oven, as most get to 300c. The sparks you see, are possible to read the material composition from, but i'm not that skilled.
typically with a spark test you're just looking for carbon content. The hot carbon in the spark will combust when it hits air, so you'll see sparks breaking apart in the air.
@@DamienDarkside yes, exactly. Steel strikers are typically made of high carbon steel for this exact reason. More carbon=more sparks=better chance of starting a fire (also better chance of making a good knife usually) ;)
This is why I get so mad at guys on Forged in Fire quenching steel at the wrong temperature, you can fucking see the temperature of the steel by looking at it. I love how the one guy who was color blind put salt on his knife so he could see the salt melt and know that was roughly the same temperature to quench his steel at.
Ngl, I was worried about you, seeing how close to the crucible your camera was and how many sparks were coming out but, as usual, I’m glad you ended up okay. Also, I love how your polished ingot looks at the end, lol. It looks like a metal eraser that I would love to fidget with.
No hammer at the last second?! You know what, we’re not even disappointed, knowing that you’re alive and well and still doing what you do best and sharing it with us, is everything we can hope for.
It is really funny how a machined piece of refined metal is just a boring regular old nail and returning it to a more rudimentary state by hand is so compelling. This reduced the raw utility of the nails tremendously, and can you even imagine how much energy it would take to get that hunk of steel back into nails, or how much it took in the first place. Technology becomes so mundane, yet the basic properties of matter remain fascinating.
Induction heaters are great. We use one in work to heat machine tool holders. Basically the end that the cutting tool goes into is slightly narrower than the shank of the tool being put in and the induction heater heats this end to expand it (in 2.5 secs) Put the tool in and it shrinks to grip the tool when it cools. Necessary for the 30k rpm they run at
I do blacksmithing and I'd love to get one of these for casting brass and other metals (not steel though), but the amount of power it takes to run one is more than I want to pay for.
I remember from a time I was taking a class on blacksmithing that, if you're trying to heat up steel for forging, then the sparks are a bad sign. It means you burned away all of the carbon or something. But that was for forging, not melting.
yup, that's a big problem in steelmaking. A lot of times the procedure is to add sacrificial aluminum to the melt, which will preferentially combine with the oxygen and form alumina that you can remove easily. It's referred to as "killing" the steel, because it goes from being very sparky and active to very.... dead.
You didn't burn away all the carbon, but you destroyed the structure of the steel; and it will be full of cracks. The sparks are because you're getting close to the melting temp of steel.
@@Nukestarmaster The steel doesn't really absorb carbon from the graphite crucible, if you watch someone do the process of making crucible steel out of iron, they still add a lot of carbon to it to make the steel. Steel just loses carbon the longer it's hot, so if you leave it in a forge for a very long time or in an open crucible like this for a long time it would eventually lose the carbon; the biggest loss of carbon is when you quench; which is why if you watch Forged In Fire the judges talk about how if they quench a knife like 14 times it won't have much carbon left in it.
Depending on how you cool it, you can end up with completely different properties in the metal. Steel that is cooled slowly becomes annealed, making it slightly softer and easier to bend, while quenching it in salt water quickly will make it harder and more brittle. If you ever see blacksmiths quench a sword into a bucket, that's what they're doing; hardening the metal so it holds an edge longer.
To add to that at least in knife making we tend to use a oil rather than water, since the water cools the metal too quickly and can cause stress and cracking in blades.
You can't just quench it though, you also have to temper the steel back after, or it is too brittle and will break. Also we usually use oil and not water, because the shock of the temperature change is a lot less if you heat up oil and the steel goes from about 1500 F to 140 F instead of whatever the temperature of the water is.
Neither. Metals do this very interesting thing when heated where they change colors. The temperature of the metal determines its color. This is called heat coloring or heat tinting. The sequence you see, straw yellow -> yellow -> brown -> purple -> blue -> pale green/blue is the sequence for steel in particular. The cool thing is that this is permanent until you heat it metal again
I misread the tiltle and thought it meant human nails, and I was curious how Nile Red was able to acquire that many human nails to melt in the thumbnail lol
You leave on 2 table lamps with 2 different kind of bulbs. You wait to see which type of bulb burns out first after a while and how long it takes for each one. Would you consider this example to be a scientific experiment ? ., ;,😊
I work at a steel mill where we use an electric arc furnace. In order to protect your steel you need a good layer of slag. This prevents oxidation and the spark reaction you had. Tapping the heat from the bottom also prevents the slag from going into your mold seeing as the slag floats. Cool stuff though!
If you get steel hot enough to liquify, it is no longer steel, it is molten iron. The fact that you used a graphite mold means that as it cools it will rip carbon from the mold and turn back into steel. You'll notice that blacksmiths don't melt the iron, but rather just use heat to make it malleable. This is because that way they can re-shape it without losing the carbon, as you would with excessive heating. Also, anybody who is watching and wants to try something like this, make sure the cables and socket are rated for that current draw. 3,500 Watts at 120 V is just shy of 30 A, so if you are not using cables that can handle that, they will heat up rather quickly.
The mold does not take any significant amount of carbon from the steel lol, melting steel also doesn't make it iron again; it has the carbon in it and most of that stays while it is melted; in fact cast iron actually has more carbon in it than most tool steel to help it cast better. The reason why we (yes I am a blacksmith) don't melt and cast the steel is because that process can crate bubbles and other impurities in the steel that would make it much more likely to break.
Hey Nile, I'm a student. Please consider making a video on determining acidic strength of organic compounds. For example, comparing CH3NO2, CH3CHO, CH3F, CH3CN. Would be a great help for me.

That's called shrink fit, it's a pretty cool process. I designed a few induction shrink fit applications.
I do blacksmithing and I'd love to get one of these for casting brass and other metals (not steel though), but the amount of power it takes to run one is more than I want to pay for.
It is amazing how you make anything sound exciting!

Always the best, and still the simplest, scientific experiments!
I remember from a time I was taking a class on blacksmithing that, if you're trying to heat up steel for forging, then the sparks are a bad sign. It means you burned away all of the carbon or something.
But that was for forging, not melting.
Iron will spark when it's close to melting. That's also why there are spark when welding
yup, that's a big problem in steelmaking. A lot of times the procedure is to add sacrificial aluminum to the melt, which will preferentially combine with the oxygen and form alumina that you can remove easily. It's referred to as "killing" the steel, because it goes from being very sparky and active to very.... dead.
I don't think that's a problem in this case, considering it's being heated in a graphite crucible, if anything it's absorbing too much carbon.
You didn't burn away all the carbon, but you destroyed the structure of the steel; and it will be full of cracks. The sparks are because you're getting close to the melting temp of steel.
@@Nukestarmaster The steel doesn't really absorb carbon from the graphite crucible, if you watch someone do the process of making crucible steel out of iron, they still add a lot of carbon to it to make the steel. Steel just loses carbon the longer it's hot, so if you leave it in a forge for a very long time or in an open crucible like this for a long time it would eventually lose the carbon; the biggest loss of carbon is when you quench; which is why if you watch Forged In Fire the judges talk about how if they quench a knife like 14 times it won't have much carbon left in it.

NAILED IT!
Depending on how you cool it, you can end up with completely different properties in the metal. Steel that is cooled slowly becomes annealed, making it slightly softer and easier to bend, while quenching it in salt water quickly will make it harder and more brittle. If you ever see blacksmiths quench a sword into a bucket, that's what they're doing; hardening the metal so it holds an edge longer.
To add to that at least in knife making we tend to use a oil rather than water, since the water cools the metal too quickly and can cause stress and cracking in blades.
You can't just quench it though, you also have to temper the steel back after, or it is too brittle and will break. Also we usually use oil and not water, because the shock of the temperature change is a lot less if you heat up oil and the steel goes from about 1500 F to 140 F instead of whatever the temperature of the water is.

Zinc

Yesnt moment
Neither. Metals do this very interesting thing when heated where they change colors. The temperature of the metal determines its color. This is called heat coloring or heat tinting. The sequence you see, straw yellow -> yellow -> brown -> purple -> blue -> pale green/blue is the sequence for steel in particular. The cool thing is that this is permanent until you heat it metal again

I'm honestly much more impressed that we are able to make nails from steel than the other way around
0:20 “very carefully transfer all the nails into the crucible”
Yeah, right! More like, dumping it in the crucible.
Hey Nilered. Can you post the link for this in the description or comments? It'd be very useful to have something like this for a lot of my projects
I work at a steel mill where we use an electric arc furnace. In order to protect your steel you need a good layer of slag. This prevents oxidation and the spark reaction you had. Tapping the heat from the bottom also prevents the slag from going into your mold seeing as the slag floats. Cool stuff though!
I'm so glad this dude has plenty of stuff to satisfy his curiosity.
The thought of having him bored for too long is very scary.
If you get steel hot enough to liquify, it is no longer steel, it is molten iron. The fact that you used a graphite mold means that as it cools it will rip carbon from the mold and turn back into steel. You'll notice that blacksmiths don't melt the iron, but rather just use heat to make it malleable. This is because that way they can re-shape it without losing the carbon, as you would with excessive heating. Also, anybody who is watching and wants to try something like this, make sure the cables and socket are rated for that current draw. 3,500 Watts at 120 V is just shy of 30 A, so if you are not using cables that can handle that, they will heat up rather quickly.
The mold does not take any significant amount of carbon from the steel lol, melting steel also doesn't make it iron again; it has the carbon in it and most of that stays while it is melted; in fact cast iron actually has more carbon in it than most tool steel to help it cast better. The reason why we (yes I am a blacksmith) don't melt and cast the steel is because that process can crate bubbles and other impurities in the steel that would make it much more likely to break.
Hey Nile, I'm a student. Please consider making a video on determining acidic strength of organic compounds. For example, comparing CH3NO2, CH3CHO, CH3F, CH3CN. Would be a great help for me.

If NileRed was in a dark fantasy film he would be the weird but powerful potion maker/wizard/smith everyone goes to but few can comprehend his immense power
But he would try his best to explain his arcane knowledge to his spectators on every show, and at least a handful of people would walk away from them having learned something useful.
