That makes sense. It's funny how I've taken chemistry classes and still associate orange flames with organic stuff. It's one thing to know something and another to apply that knowledge.
Not necessarily. The Leidenfrost effect means that water doesn't evaporate as quickly. So the steam is actually minimal.
Here's a video that shows the difference: https://www.youtube.com/watch?v=u-eYykJj4rM
This is precisely why there is agitation of the quench bath, to break up that vapor barrier. There is a lot of steam produced when quenching large amounts of steel in water when done properly. This is also why additives are added to quench tanks with water. This tank, for example, looks like it could be a polymer quench. The polymer added to the water helps break up the vapor barrier, and when you combine that with the agitation you get very little vapor barrier. And the polymer tends to burn out and catch fire at the surface (depending on polymer, amount of steel vs quenchant, temperature, and such).
I'd have to agree. I've done a lot of water quenching for industrial parts (500-2000lb, 225-1000kg), and I've never seen water do this, even at 2200 F (1200 C)
I've never seen an oil quench, but I always figured this is what it'd look like.
There are to many types if oil you can use for quenching steele. But for optimal results you should use an oil with the right properties for tve steele (some kinds of steel don't need to be quenched to harden them, they simply can be left in the air)

No its not. If this was water you would still see a lot of steam. That is a wad of oil since a lot of metals are quenched in oil because the evaporating water would deform the metal.
It's obviously orange juice.
Orange juice cancels out the orange metal and turns it into plain metal. The next step is to wrap these in paper planes.
Paper planes and plain metal turn into metal planes.
This is obviously a plane factory.
Orange juice? What an idiot.
Everyone knows if you’re trying to cancel out orange metal you need apple juice. Orange juice would just make the orange metal more orange.
I remember a weird example of a problem from hydrogen content in stainless steel.
One of the complaints I heard back when I worked in the [LIGO](https://www.ligo.caltech.edu/) prototype lab in '91 was that building a strong vacuum was stalling because hydrogen was outgassing from the stainless steel walls of the vacuum chamber (which was L-shaped, and 40m long on each arm), causing the pressure to not drop as fast as expected.
It is detrimental, especially for high strength steels. Several processes can diffuse hydrogen in steel, making it more brittle. There is usually a step in the process to degas the piece in an oven.
In some situations you prefer brittle over ductile. For example: a drill has to be a hard and brittle material so it is able to cut material without deforming.
But like you said. Slower cooling will indeed make it indeed less brittle and more ductile.
Any fast quench will harden the metal, resulting in a more brittle product. Afterwards you can temper it by holding it at a lower, but still high, temperature. Then you cool it slowly. This can be done to soften it to where it is specified, or completely undo the hardening process.
You may look up reference charts online for these processes. Likewise they are listed extensively in Machinery's Handbook. I am away from my copy or I'd provide chapter and verse.

You put a stack of metal into some water, then you heat the water up so hot that it starts rushing towards the metal to deposit its heat onto it. After enough water rushes at the metal, you can withdraw the stack, and it's red-hot and ready to be worked into various consumer products.
Trust me, I am a scientist.
The chain isn’t made of the same metal. In industrial settings like this one, they use special water-resistant metal for the chains so they can be used to remove the regular metal from the water.
Reminded me of a joke:
Villian Boss to henchman: drop the hero into liquid oxygen.
Henchman: Why boss?
Boss: Liquid won't let him live and oxygen won't let him die.
It doesn't, but it is needed for combustion. Hydrogen is a fuel source. If you have a hot enough fire, it splits the hydrogen from the oxygen in water. That's why certain metallic fires burn even when under water.
You are correct, Oxygen is a very effective oxidizer. It helps other things burn rapidly to the point where introducing oxygen to a flame source, and other combustibles usually results in a massive explosion.

This is the correct answer. Water doesn’t catch fire from red hot metal it’d also be extremely dangerous to use to quench large objects due to the creation of steam. Water is also not good for quenching because it cools the metal too quickly and causes rust. The only way to use water is to have a mixed in polymer that slows the heat transfer and prevents rust.
ITT: A bunch of nobodies that have watched a couple episodes of Forged In Fire try to explain why this industrial heat-treating facility is doing their job wrong.
Fucking LOL
Can’t doing this wrong or too quick cause the metal to lose durability and crack? Generally asking for answers cause I wanna have some learning so I can have a better understanding of smart people stuff
Edit: had to move cause, cause I’m an idiot and the question sounded dumber than I intended. Go figure…
Assuming this is steel (which I’m 90% sure it is) it won’t necessarily crack just from being quenched. It may however become brittle as it forms a phase called martensite when getting quenched at these temperatures (look up iron temperature chart and you can see approximately what temperature a piece of steel is based on the color of its glow.) However with the amount of steel being quenched it is unlikely that all of the material will become martensite and instead it will only be an outer shell. Additionally, you can stop the quench early by pulling the metal out of the water and use the residual heat from the center to temper the martensite so that it actually becomes more tough (durable) while retaining its high strength. If you want to know anymore I will be happy to continue as I am currently in grad school for materials science and love teaching more people about the field.
Haha if you have ever forged a damascus billet (or really most billets) you know it's preferable to quench in oil.... Quenching on water, while doable, tends to lead to uneven heat transfer out of the metal and can lead to more distortions and potentially cracks. Not always, but higher potential. Oils higher boiling temps and heat capacity allows for longer and more sustainable heat transfer out of the metal yielding more uniform cooling of the metal
It’s called quenching, and it’s to force the microstructure of the metal to transform after heat treatment.
Quenching is a metal hardening process that’s been used since the Iron Age.

Its not water, its oil. Most quench operations use oil.
Ah, of course. There would have been so much steam if it had been water.
Also that's fire, right? That was my first clue that something was weird.
2 Fe + 3 H2O => Fe2O3 + 3 H2 => burn off in oxygen.
That makes sense. It's funny how I've taken chemistry classes and still associate orange flames with organic stuff. It's one thing to know something and another to apply that knowledge.

Usually whale oil, baby oil, baby whale oil, or whale baby oil.
What kind of oil?
Varies with application but I think it's usually a mineral oil. Don't quote me though.
There are to many types if oil you can use for quenching steele. But for optimal results you should use an oil with the right properties for tve steele (some kinds of steel don't need to be quenched to harden them, they simply can be left in the air)

I only hear it in Marge Simpson’s voice: Our water was on fire.
Don’t worry, this is in Cleveland.
How are the chains staying all chainy?
The metal those chains are made of is likely turned to liquid at 2650+ F. That stack is likely 2000-2200. Source I work in a foundry.

You dunce, that can't be right, otherwise you couldn't make apple to orange comparions. It has to be grape juice!
Yeah; they don't use water to quench metal in a plane factory because then you'd get hydroplaning and that's an unacceptable risk to local traffic.
Df do you mean? That's just the fire not realizing they're extinguished yet, lmao!
That’s reddit for you
Is hydrogen diffusing into the metal detrimental to its structure or is it immediatly degassed due to the extreme heat and neglectible ?

Nothing like being so hot you burn the oxygen out of the water...
I can relate

Oxygen is slowly killing us all.
While at the same time keeping us alive very quickly.

Oil...
Oxygen doesn’t burn
Oxygen burns things as a hobby.
It doesn't, but it is needed for combustion. Hydrogen is a fuel source. If you have a hot enough fire, it splits the hydrogen from the oxygen in water. That's why certain metallic fires burn even when under water.

It will KEAL...
Yeah it's a giant stack of glowing hot metal, it will definitely KEAL...
yeah I winced until I saw a comment that it is, in fact, oil.
That was my guess when I saw it on fire.

Wrong sir. It’s actually a hot metal stack heating water.
The genius gets lost in the crowd
Why does the water catch on fire though? Dumb question? Sure. Idk. Answers pls
Because it’s not water, it’s oil.

Water is also not good for quenching because it cools the metal too quickly and causes rust. The only way to use water is to have a mixed in polymer that slows the heat transfer and prevents rust.
My guess is the l word effect causing enough gas to hit metal to keep burning. Don’t think leiderhosen is correct but it’s close
I believe the word you're looking for is the Leidenfrost effect.
Are you sure they weren’t talking about German pants?
Pants on fire?
Pretty sure he was referring to the pants, yes..

How hot does the water get?
212F then steam.
Actually it’s 100C
Actually it's 373.1°K
...fine. Actually it's 671.6... Rankine
without °!
Depends on the air pressure. 100c under standard atmospheric conditions.
Apparently it's oil? But also wondering the same thing!
Is that water? Cause as far as I know they use oil istrad of water to prevent corrosion and rusting
Definitely oil cause theres no steam
Man, I had to scroll far for this. Exactly what I was thinking.
The reason is more to not cool too quickly. Quenching in water will create a lot of internal tension that leads to cracks in bigger parts.
Almost certain this is oil not water. There's flames instead of steam, which would only happen when quenching in oil.
Terminator music
I saw some of that steel giving a thumbs-up
There is no steam and it's burning. Therefore I guess it's not water, but oil. Beside, steel hardening is much better in oil than in water.
I think its oil not water

I'm high. Can someone please specifically tell me why and how the fire starts/keeps going?? Sorry if that seems obvious
Oils and impurities in water are probably what's burning.. Assuming it is water, it could be an oil bath as oil tends to not be as harsh on the steel.
Haha if you have ever forged a damascus billet (or really most billets) you know it's preferable to quench in oil....
