Hydraulic Press Vs. Ball Bearing Frozen In Liquid Nitrogen + Red Hot Ball Bearing 

Thanks to my friend Tami for explaining the weird results for me. If you are interested on hardening and heat treatment of huge steel parts go check out this video on Beyond the Press ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_lMw80S6ldc.html There Tami shows their heat treatment facility at ATA Gears.

I've heard of people cooling their balls with ice packs to improve performance, but using liquid nitrogen seems a bit hardcore to me.

Cryogenically treating steel can make it surprisingly strong. It's used to heat treat drill bits sometimes

I'm sure that you and the Slow Mo Guys would have a great time together no matter what crazy experiments you decided to do! (But I'm sure they'd prefer to visit Finland in summer :D )

I never thought I'd see the day where anything actually STOPPED the hydraulic press at maximum. Wow!

It would be cool to see a slo mo guys team up vid

That 320000fps shot at the end is absolutely amazing. You see visualizations of high speed explosions and they obviously don't do it justice. The way the pulverized material hangs in the air at specific angles and in specific color ranges is really cool.

So great to see Anni being involved in vids again. Even just having her reactions on audio really brightens the mood of your vids.

There are few visuals more satisfying to me than watching scale flake off of hot steel under pressure.

these videos are getting more and more crazy, keep it up !

WHAT THA hELL 2:08 I love the finns accent to funny people! from sweden!

yaaay, Anni's back 🙌

I love your videos, but when Anni is there providing reactions, it just kicks them up a notch. 😂

Making the balls colder increases their brittleness, but what that really means is its hardness goes way up, but their ability to absorb shock goes way down. so it would be easier to throw a frozen ball bearing at the ground to break it than to just apply force to break it.

Thank you for showing up Anni, you make every video better, it's more like a family environment..

Hydraulic Press Channel has the strongest balls of steel!

Wow! Your filming setup is so much better these days!

Freeze frame at 0:38 is a great thumbnail! Also nice to see Anni again :D

Hi Anni! Was cool to see the heat transferring from the pressure points down to the middle of the ball

What a wonderful example of how pressure creates heat , as you can clearly see the transition as you work the press.

As an engineer student, it is cool to see the theory in practice

2:20 Sounds like an accent an American actor tries to make to sound foreign. 😂

High quality content. Loved the slo-mo. Glad to see Anni there. Cheers.

I like the videos when Lauri makes things "more explody."😁 Prrritti Guud. 👍

3:30 Unexpected Cosmo and Wanda.

This has likely been said already, but I’m almost certain the ball bearing from the previous video didn’t get red hot at all. What you saw was a frame where the sparks blurred as they shot across the flat surfaces of the press tools and the rounded surface of the bearing reflected the blurred sparks making it appear as if the bearing was hot.

The faster cameras are nice, but we come here because of you and your ideas.

The red hot ceramic ball was probably the most dangerous piece you ever tried to crush... this could've gone really wrong! 😅 /edit: I probably got that wrong. Maybe the ceramic ball wasn't hot.

That Slo-mo was gorgeous... 😍

my theory is the little dent that formed from destroying previous balls create a "holding" cushion that makes the cold ball harder to crush. pressure with less surface create more penetration, the sunken dent create more surface that caused the ball become harder to crush

I would love to see a collab between your channel and Slow-Mo-Guys. that would be a greatly amusing and maybe even educational episode. Great content as usual either way.

The cryogenically hardened ball bearing was intense. Is this the first time the all-powerful Hydraulic Press has been defeated?

I absolutely love this channel. Thank you for your hard work and dedication to showing us your fantastic videos!

I might be high on sugar but when I hear that slomo blast sound 0:53 and see those lamps falling inside, it cracks me up 😂🤣☠ thank you for the entertainment 🖤

"Big ass bearing balls" 😂. Idk why that caught me off guard, but I literally laughed out loud. That's funny af, thanks for that

Thank you for showing the super slow motion versions!

I have been watching your videos for about a year and got super hyped as soon as I saw the Phantom camera at the end. Since 2013 I've been a big fan of The Slow Mo Guys and they are pretty much half of my inspiration and smarts for cinematography. One of my favorite things about your channel is the amazing camera quality that each and every video delivers. Image sensor size and dynamic range often matters more than resolution. The only thing better than the HPC is with the shenanigans of Gav & Dan. Would be a dream come true if you guys collaborated.

This channel takes the theme of Bad idea to do with heavy machinery and Hold my Beer , to the next level now with Science, Haha. I luv hearing the guy's Finnish accent , and when things Explode, the reactions are Priceless ! Slow Mo shots are really cool to see , Pun intended.

Anni is back! Haven't heard her laughter in the last few videos I watched.

The cams are a lot, so undersood, but the fact that the small bearing just vaporized is insane. Love it as always!!!!

18K views + in one hour. I work with steel, and to see what loading this stuff can handle is always amazing. You have a great channel, and all the hard work that goes into all this is very much appreciated . I also replay the exploding bits. What this shows us is how the material is held together atomically. And the energy that is released when subject to force loading. I came across an interesting fact the other day. Each atom in a atomic nucleus is held together with a force of 20 lbs. So how many atoms released their 20 lbs at 7:53? Another fact I came across was that you could line up 11,000,000 atoms across the point on a pin. So the energy released here is enormous. Kind regards, and greetings from Africa.

Chrome Alloy Steel Balls, the most common bearing alloy, are manufactured from steel of the hardening type AISI E-52100. 52100 is a relatively simple steel with 1% carbon and 1.5% chromium, and small amounts of Mn and Si. In use since 1905.

This channel has always been Awesome!!!! You guys are cool cats!!

Really miss the crushing of really dangerous clay items at the end of each video.

The colored nails of your wife are very very nice

Thank you for getting that camera for this video! The footage was absolutely incredible!!

It's my first time I watched your video 🤣 you sound like retired Mario by the respect man keep it up

The way that everything jumps, falls apart and gets absolutely destroyed around the press in every video is hilarious 😅

I love his temperature messurement skills; »It's cold, alright!?« 🤣👍

0:48 that FUCKING SCARED THE HOLY SHIT OUT OF ME.. JESUS

Just wanna say the last one in slowmo was so beautiful. Good job

i think the balls dont explode as easily at higher force, because as the force increases, the ball is making bigger dent in the tool, however bigger dent means bigger area and the stress is distributed more evenly on the ball. Harder tool would definitely make it easier to crush the balls. Making it all out of very strong steel might be expensive, so i suggest using only metal plate at the end of the tool

You heard your community and showed us a (past) video with real slow mo. Thank you :)

Fantastic video, always love watching the press squish things.

I just want to say I'm glad to see more original content from you recently. The stream of compilation videos just doesn't engage me at all, the part I like watching for is hearing what you're doing, why, and what your expectations are. Explosions are just a bonus, I'd watch without them lol

Have you ever tried freezing the tools? Like, the base plate and the crushing part??

Excited for spess-ee-all guest!

Always fascinating. Always exciting no matter what the outcome. Thank you

The slow-mo of the BB exploding looks exactly like the Death Star explosion.

the cryogenic hardening made it waaay stronger

I say your high speed cameras are good enough. I just appreciate your content regardless.

Omg I'd love to see a Hydraulic Press Channel and Slowmo Guys collab!!! 🤩

A great demonstration of fine particles of iron being pyrophoric.

Ball bearing crushing is my favorite thing so far.

Can we get thermal imaging while pressing? That would be helpful with slow motion and doing calculations on different materials. Awesome Videos as ALWAYS!

I now hypothesize that our understanding of the universe’s Big Bang is nothing but a ball bearing being smushed

Hi Lauri Thanks for your videos. I am not a specialist, but I think you should be careful with some materials, when they don't fracture in the press. I think that some materials like hardened steel and ceramics can sometimes "store" internal tension, and will be able to violently fracture, after you take them out of the press. With kind regards Thomas

At least it’s comforting to know Dracula picked up a less violent hobby.

I love the high speed shots

Slow motion was Like a star collapsing on itself an going super nova. You created your own Big Bang

Are they back together? I had thought they were having issues. It's so nice to hear her laugh again.

Great video Lauri and Ani. Thank you.

Amazing, and yes many steel alloys increase strength when at lowe temperature.

Nice seeing Anni back again

This is what I like about this channel, one minute in and we already got excellent content. No dawdling around, no clickbait-- a small explanation and we get to what we came for.

Very nice pink and yellow nails. Lovely display of ball bearings!

the shedding of the oxide layer is pretty cool

3:07 WOW ....look at the upper left side of the ball bearing right when he said "hammer" there was a small stroke of lightning 😀😀

"Vat 'de' Hell" is so freaking cool :D LOL nice catchphrase

This is crazy 😂 and super entertaining

Yes to a HPC and Slow Mo Guys collab!

Congratulations on discovering the power of cryo-tempered steel.

7:28 looks like a forming galaxy

cryogenic treating of steels is a VERY time dependent process, try holding your parts at liquid nitrogen for ~2 days for some crazy effects.

Seeing your new cameras reminded me of my max stats in the Hydraulic Press mobile game lol.

I love you guys videos this Channel and beyond The press I've been watching you for a few years now keep up the good work..

Time for the mass kick-starter to begin. You have our love, our channel subscriptions, and soon will have our money. Sisu.

A colab with the slow mo guys would be so epic!!!!

Really like the way you explain the physics of what is happening to hide the fact you are soooo excited to blow things up!!! HELLO ANNI x

I happy with what you do and have no complaints

Ahh, excellent way to start the afternoon ;D

It’s so nice to see high temperature oxidation in its purest form

It’s converting the pressure into energy as heat. That means you are increasing the pressure needed by decreasing the amount of heat in the steel first. Lowering the temperature increases the energy needed. Because your tools material is close to the same material strength. It’s going to fail, unless you have something with higher density.

What a development. Hot steel can be manipulated with force. Entirely amazing.

Definitely deadly but a hell of a lot of fun!

The collaboration between this channel and the slo mo guys is long overdue!

The slow motion is awesome, but don’t go into debt over it.

You can think of it like this, metals are strong when they are frozen. So long as the impurities are properly removed, it will freeze together at near the same rate, keeping it strong. If anyone knows about old sword smithing, you beat the metal when it is hot to shake and help remove impurities. But it is doused in water to cool it quickly and help surface the impurities to remove them; and that can done over and over depending on the desired result, at least a couple of hundred years ago it was. Different rates of cooling also changed results. The process is called quenching. There is full quenching and slack quenching. Slack witching is the one done to make a stronger product and, in a way, what you did with the nitrogen because it was already cooled first before you made it cooler. The most important factor is what I hit on earlier, the cooling and heating must be uniform, otherwise it will break apart.

does any of the exploded metal loose any of its properties if it was melted back down in to a lump of metal?

Temperature is the willingness of the atoms to move. So the reason why the cooler ball is just super hard was because the atoms in that metal is barely moving therefore incredibly hard, and opposite for the hot ball where the atoms likes to move alot and reposition.
