Episode 95: You Don't Know Anything About Steel

[@the_real_ch3]

I don’t know why the algorithm blessed me with this today but I am very thankful

[@TaylorSparks]

@@the_real_ch3 hahaha. Glad you enjoyed it

[@August._b]

This was a double feature for me. Listened once while falling asleep and it put me right out (which was the goal). Listened again while fully conscious and found it super informative as a materials engineer. Rare for a podcast to be so good at both of those applications.

[@TaylorSparks]

@@August._b yassss. Glad to help with sleep and knowledge :)

[@dianapennepacker6854]

How do you actually retain the information? I find myself forgetting basically everything quite quickly. By the next day I totally forget most of the things I watched. I hate it.

[@TaylorSparks]

@@dianapennepacker6854 super frustrating for sure. Notes and discussion really help

[@cammccauley]

Omg the algorithm has blessed me. I downloaded the entire podcasts playlist. I’m a machinist studying to be a materials engineer and this is fucking great stuff. The entire podcast

[@TaylorSparks]

@@cammccauley heck yeah!!

[@smolcryingpepo]

why didn't you choose mechanical engineering instead? materials engineering is more lab or computery then industrial, which i assume you are aiming to work in, manufacturing?

[@bobopokomono-nu3gv]

the internet may have been a bad idea, but the marriage of science and youtube makes up for everything. thanks, i learner a lot!

[@bondvagabond42]

Im a machinist/ marine diesel mechanic, and wooden boat builder, but i actually started off studying philosophy in college. I have been fascinated by the evolution of technology, especially old technology that is still close to or even surpasses some modern tech. By far one of the most fascinating things is steel. Like, you can make it softer, so that you can cut steel with a piece of itself. Before the invention of fancy pyrometers, you can get pretty accurate changes in hardness by looking at the different colors that steel glows when heated, and those colors are in the visible spectrum of humans!?! In scandinavia and other parts of europe, the "bog iron" just precipitates out of the bog water, so you can develope iron technology witbout wven haveing to develope mining technology. Say you were an iron age peasant, but you were gangster, and you got an iron knife from your dad when he died. If he died in a house fire, the carbon in his body would infuse the surface of the knife with carbon, making the surface case hardened steel, so like the spirit of the ancestors infused your blade and made it better. Im an agnostic, but the usefulness of iron, and how well suited we are to make iron stuff is the thing that makes me question my agnostic beleifs more than anything else, hah, iron is just too convenient.

[@TaylorSparks]

@@bondvagabond42 hahaha. I love this whole comment. Spoken like a philosophist!

[@raayonaim]

One of the best episodes, not only in Materialism Podcast, but in any podcast I've ever listened to. I love how you think about your students needing a centralized resource for finding a grade. Perhaps the associations should develop some "buying guide" or flowchart, hopefully interactive.

[@TaylorSparks]

@@raayonaim dude, this is such a great idea

[@ethanallenhawley1052]

This was fascinating! I am so glad such knowledgeable people exist in this world. Thanks all three of you, especially Caelan Kennedy.

[@leightondawson9247]

This is awesome! The podcast I didn't know I needed So glad this was recommended; shared with a bunch of other folks I think will find it interesting

[@TaylorSparks]

@@leightondawson9247 gracias !!

[@jameskelly827]

Incredibly interesting! The levels of expert knowledge just casually thrown around in this discussion were fantastically enjoyable and informative. I am very much looking forward to watching my way through all of your channel's videos.

[@alexandermiller6583]

This podcast is exactly what I’ve been looking for, for years. THANK YOU

[@TaylorSparks]

Dude, I'm so glad you're enjoying it!

[@jimsvideos7201]

Thank you for this; these distillations of so much knowledge are a treat.

[@TaylorSparks]

@@jimsvideos7201 thank you for listening! We've got 94 other episodes. You can check out and new ones twice a month 😜

[@wspad2136]

Hi Taylor, The discussion on steel composition is fascinating. I have some questions but first a caveat: I'm definitely no expert so I'm likely wording this wrong. Questions: "killed steel" goes through a deoxidation process for the purpose of obtaining a tighter lattice/grain structure. It's my understanding that the final composition includes Iron (Fe), Carbon (C), Manganese(Mn), Silicon (Si), Phosphorus (P), Sulfur (S), (Oxygen (O)

[@greglaroche1753]

This is a very interesting podcast. I’ve learned a lot. I wish you would do more in depth research related to steel and other metals used in manufacturing processes. Thanks.

[@TaylorSparks]

@@greglaroche1753 yeah, we try and find the balance between breadth and depth. We are for sure interested in doing some follow-up episodes that go into greater detail

[@greglaroche1753]

@ I’m subscribed and waiting.

[@gasolinelollipop]

Great podcast. Consider a changing image screen so we don’t get screen burn. I can now always see your podcast on my TV

[@TaylorSparks]

@@gasolinelollipop good idea

[@byronlovesdrifting1]

Damn may start listening to podcasts again.

[@TaylorSparks]

@@byronlovesdrifting1 love to hear this

[@sankalp3513]

Good episode. Would love a future episode on the status of steel manufacturing by direct reduced iron (DRI) processes.

[@TaylorSparks]

@@sankalp3513 actually, we just reached out to a company in this space on this topic. Stay tuned

[@vyvianalcott1681]

This is the most fascinating podcast I've ever listened to, usually it's just background noise but I was actively listening to every word. Keep up the great work!

[@preauxtip]

I'm no material scientist (in fact my degree is in sociology), but I have had a fascination with the science of steel for a long time and have done a lot of reading and research on my own. Some of the best resources I've found have been the late Dr. Thomas Eager's lectures posted here on KZbin as well as the book 'Knife Engineering' by Dr. Larrin Thomas. The latter is hyper specialized towards the blademaking hobby (where my interest stems from) but has some fantastic content and is very technical. Also borrowing the textbook 'Engineering Materials 2' by Michael F. Ashby from a friend of mine helped build a great foundation.

[@davidg3944]

Tom Eagar was both a great professor and a very approachable resource at MIT. His passing was something I found (to my distress) while searching for information on welding. I'll check out his videos that you've mentioned, thanks for that.

[@6AK5W-JAN]

5 minutes in, this is a waste of time without graphics! How are you talking about crystalline structure without pictures? I understand this was originally a podcast, but when you put it on youtube you should have added diagrams.

[@PaulPassarelli]

Fooey! You're a podcaster, you need to learn how to set your *AUDIO* levels properly!

[@TaylorSparks]

I'll get Jared on it!

[@robertfontaine3650]

34 minutes in and no inconel yet.

[@TaylorSparks]

@@robertfontaine3650 We need a whole nother high alloy episode

[@robertfontaine3650]

@@TaylorSparks yup. And the history of steel is another way to go at it as well. English steel in the late 1700 to silver steel into an explosion of alloys for various uses. Love steel and iron.

[@davidg3944]

Inconel and its relations are predominantly nickel and chromium, with Fe being a relatively small percentage. I wouldn't call them steels at all.

[@ryanbeard1119]

Talk about some more advanced stuff

[@TaylorSparks]

@@ryanbeard1119 always tricky to ride the line between depth and breadth. We want to make it accessible to everybody while satisfying the experts. We will probably do a follow-up episode where we can go into greater detail

[@ryanbeard1119]

@TaylorSparks ok, can you explain, I though H C s let's say 1.00 percent carbon, not molar or molecule number, but I thought you said the number was way lower, so does that mean carbons weight is way greater than iron molecule?

[@Maxim.Teleguz]

Steel is too heavy.

[@Aristotle675]

The audio levels are totally out of whack. Please do a bit of research on this and how to mix and record audio for podcasts. It is something that requires a bit of knowledge but it’s not that complex if you follow some simple rules

[@TaylorSparks]

I'm sending my audio guy to boot camp lol. He's gotta get this fixed

[@Aristotle675]

@@TaylorSparks love the show, I listened to this episode on Apple Podcasts where I think they do some audio processing (compression & limiting) on their servers when you upload. I’m glad KZbin recommended this to me

[@Splarkszter]

If you deleted the first 35 seconds of the video I wouldn't be confused on if I clicked on a serious video or an AI generated flop. Anyways. Sadly podcasts aren't my thing, I like educational videos like how Fermilab and TheScienceAsylum do.

[@meder07]

Hobbyist learning how to TIG. Friend/instructor got into this a little, searching for more led me here. Tried basic welds on aluminum and some steel coupons, such different interesting properties. Would be interesting to hear details about applications such as what happened at Blue Mesa Reservoir CO. Casey Jones covered the the T-1 steel story but more from an engineering standpoint.

[@saraagan8169]

Thanks to this amazing podcast I learned a lot about family of steel 🪷 😊
