Unfortunately I have missed the disclaimer and have done exactly this at home. Just by accident I have applied 600 tons of pressure to my metal. What shall I do now?

400degF may be still good, but the "fun" starts above 450degC, where the recrystalization starts. Not F, but C. That is not the same. And at 800degC pretty much any construction steel becomes like butter. And common house fires (fueled by carpets, furniture,...) are able to go way above that. The purpose of the heat protection "paint" is to absorb the heat (by decomposing itself) for at least the time needed to evacuate people. But when all the burning things became soaked with kerosene and also burning two floors below, the extra heat make the coating to decompose way faster... Well, we are talking about quite a few mm thick layer by the way, so calling it a "paint" is a bit stretch, but so be it...
“I don’t get a real benefit” from watching this, besides entertainment and learning a thing or 2! But love these videos and almost stop doing anything to watch them 😂! Thankful for all the time, effort and money invested to bring these videos to us! 👍🏼
the thing about steels is once you heat it to above 400c, you've ruined any hardness or tempering properties it had beforehand, even if you allow it to cool back down to ambient room temperature. it will be roughly as soft and malleable as cold mild steel unless you can reharden and re temper it, which for something that big and thick, is really hard to do.
This is the key thing “9-11 truther’s” fail to grasp. It’s entirely possible to hit 450c in a contained fire. You don’t need to melt steel to ruin it’s structural properties, just get it to ~450c/850f. Even 400c would likely be sufficient.
@@geoffstrickler how would the foundation get to 450 degrees if the fire extended to the top floors? And how did building 7 fall from the bottom up when nothing struck it?
Interesting, but more detail would be useful, such as the alloy of the metal, the hardness or temper. This could also be stated as the grade, for bolts & nuts.
You're the first yt channel creator to break a sledgehammer I've seen so far. Congratulations. The released every from that was amazing. Well done. Subbed you too.
It would be interesting to take the same type of nuts and go to the opposite extreme. How much more brittle would they be after immersion in liquid nitrogen?
@@truthhunterhawk3932 essentially, rapid cooling creates stress within the metal's inner structure. This does make it brittle, but it also makes it very hard since the stresses prevent the grains inside from moving
@@TheRatLikerThey’d be harder. But weaker, it will instantly explode once it goes like a few millimetres compressed, heat makes things flexible, cold makes things hard but explosive
At 07:55 the color suddenly changes to black... interesting! And one can also see that metal at 800°C, the strength drops dramatically, not only for thrusting, but also bending and pulling forces. Remember something....?
so open air burned jet fuel which is about 1100C … might have had an affect on that something causing that what it supposedly could not and be responsible for the sudden drop in the continuity of ‘being alive’ of those people in there. i am fairly sure that the floors above that point were heavier than 500tonnes… and the weakened structure was able to go downstairs after a while… hmmm its a sad sad event :( may all rest in peace.
I would really like to know how the strenght is teperature-dependend. Is there a difference if you heat it up to only 200 degrees ? I think this is a temperature which could happen to a hammer (seldom, but possible) if you work on forging steel.
If there wasn't, why would a blacksmith put his workpiece right into the middle of the hearth and even increase the temperature by pumping air into it?
Alot of metals are strengthened by work hardening, which is essentially where sliding atoms (very simplified explination of dislocations) get stuck and restrict the movement of eachother and make it harder for the material to deform. Increase strength make it less ductile. When you increase temperature these dislocations can defuse and they basically aren't in eachothers way anymore. So effectively you can heat the metal and cool it again and you will get a similar effect. Another factor, significant but not as significant is that each atom has more energy in hotter temperatures which means less mechanical stress (force over area) is needed to be applied for it the dislocations to move and the material to deform
That sledgehammer was a cast iron, and still reached 380 tons of pressure before reaching breaking point. If it was a forged iron, it would have reach 500 tons without breaking at all 😅
Everything, absolutely everything, is compressible. If the compressed thing is still in its springy region, its a spring. The base, workable and press pieces on the table all get compressed. When the victim fails, the springs, well, spring with absolutely massive amounts of energy.
This is THE PRESS, beautifull and enchanty power, few things coud resist that. Russian and american quality things, like this giant wrench. Congrats for the wonderfull work, dude!
they aren't. You need to repair them regularly, if you use them above certain pressures. Other than that, they are just build out of thick materials and use really strong cogs and transmissions to create the pressure.
Hello again Chip! Wow those are some big nuts you have there. Not to be trifled with. In the cold press test I could almost hear the nut asking for a nice hard bolt to be wound in. It would probably only flex .2 mm with those threads. The nut would be hard enough not to spread around the theoretical bolt. We could see the paint on your press adaptor plate bubbling from the heat transfer. Was that enough to remove the hardness from it? The small kiln for sure was way over 800 c. Looked like twice that. Nice work, we miss the "Here we go!" Good luck.
J'ai le même thermomètre laser et 800°C est le maximum qu'il puisse mesurer... la pièce métallique doit faire bien plus de 800°C dans sa partie basse...
I was trying to follow the gauge but didn't get the readngs you gave. Is there some kind of constant or multiplier or other adjustment that has to be applied to the gauge to get the accurate reading?
0:02 He must’ve stole the nuts, bolts and screws Putin’s nuclear weapons are made with, Koreas nuclear weapons, America’s word war tanks. This guy very likely has an anchor, a scimitar, a machine gun, military uniform in order to get all this stuff o_O And at 1:42 just from cracking that 1st thing, he easily made all the bugs possibly under his floors or within his walls wake up Colorado’s Military saw on their Richter scale a 1.0 lvl noise was just heard.
"Don't try this at home." Yeah, I have some spare change, so I will run to a local supermarket and buy 500 ton hydraulic press and metal furnace. Lidl may have them in their miscellaneous aisle.
Not entirely sure what you're referring to, but metal getting hotter when you crush it is a known phenomenon, so... Short answer is because of the second law of thermodynamics- deforming the metal takes energy which is provided by the hydraulic press, but it's impossible to use 100% of the energy spent by the press to cause deformation, so some will necessarily turn into other forms of energy including light and heat. The long answer is, well, I'm not a material scientist so I can't say much for certain. But I doubt the explanation stops at the 2nd law and goes into the physical properties of the material to explain why it heats up _as much as it does_ instead of just heating up at all.
It's important to indicate the temperature of the experiments in general. Because, hardnesses may be different. Russia and UAE have different temperatures
