The True Story of Cast Steel (Was Bessemer a liar?)

When the English clockmaker Benjamin Huntsman pulled his first crucible of melted steel out of a furnace in the 1740s, he had no idea the ripples it would send through history. Its status as one of the top tool steels has been obscured by a narrative that I (and maybe you) have always assumed was true. This is the true story of crucible cast steel.

[@andylewis7360]

A really interesting video, Abraham. I really enjoyed watching such a well researched video. Just one point, and someone may already have pointed this out. You mentioned some research from the 1980’s by Kenneth “Barclaw?” I suspect that the gentleman’s name is Baraclough which is a typical name around Sheffield. It’s actually pronounced “Barracluff”. We Brits have some pretty strange family names and the pronunciation isn’t always obvious. Try to attempt pronouncing Featherstonehaugh. I’ll lay money you won’t get it! 😂 It’s pronounced “Fanshaw” 😂

[@johncline7247]

I was just at the Hawley Collection in Sheffield last week! I really enjoyed your video, and am looking forward to the newsletter. One subject of particular interest to me is the story of Henry Sorby, who inherited a lot of money when his father died (also Henry, the H in I&H Sorby tools from 1829-1844) and used it to do microscopic analysis of steel, among other things. There's a microscopy lab dedicated to him at the University of Sheffield, and--as I understand it--Bessemer et al were very dependent on Sorby's analyses for the development of mild steel.

[@bigolbearthejammydodger6527]

A very interesting - and decently researched video, completely new to this channel. Im a Sheffield chap, not living there any more but I grew up there, was born in chesterfield(next door) have family there and I went to uni there. I can assure you that despite the massive layoffs in the 70's through 90's the production of Sheffield crucible steel is more than what it was historically - so it absolutely has been HEAVILY automated. Sheffield steel is now owned by a dutch/norweigan company which also owns the mines in northern Europe as well as the mines in Sheffield and its surrounding areas. In addition to still producing more crucible steel than it ever has, Sheffield also produces a hell of a lot of electric furnace steel and iron along with various alloys. Sheffield and its surrounding towns also contain multiple competing companies and have since the 2n'd world war, these days the universtiy owns most of the land these companies operate on and they supply the high tech industry that the city is known for today - making steel/iron/alloys for satellites, aerospace, military, medical etc etc. My father was one of the most renowned metallurgists in the nation, frankly in the world, worked in both Steel industry and Iron Industry, I worked in the aforementioned high tech industries supplied by the steel industry. The phrase by the locals is "Shit in, Shit out" and that phrase is still used today, something my dad applied to more than just steel production - often applied to business and politics. If you have any questions Im happy to answer them.

[@dicksargent3582]

Fantastic video !!! I'm a blacksmith by trade and all of what you've presented here has been of importance to the restoration / reproduction part of my work over the past 50 years. There are so many twists and turns in this history. Like the fact that one of the most important things in the cast steel process was being able to produce crucibles that would withstand the temperatures required for the process. Early cast steel crucible clays were natural bodied clays. By a fluke of nature deposits of a clay which could stand these temps was near by Sheffield. These clays not being found anywhere else stifled other manufactures ability to produce cast steel. Your interest here stems from would working and plane irons. Another interesting associated history is Disston and his search for steels for saw blades

[@rossgraham8776]

Great presentation - my knowledge of cast steel was rudimentary (like many was under the impression its production phased out in the mid-1800s) and this helped a lot to understand the process and history. Would really like to see more presentations like this

[@mickeyfilmer5551]

I used to go to Sheffield with my father in the early 1980's, he would carry steel billets made in Brymbo Steelworks (Near Wrexham in North Wales) to a Massive forge in the industrial area. These billets were forged into crankshafts for petrol/ diesel engines for the car industry. I used to be overawed by these massive machines stamping up and down shaping out the parts. Thanks for the video, I really enjoyed it, and I think others may well have enjoyed also.

[@GibsonCutlery]

This was amazing! Please do more. Subbed! If I'm not mistaken, the primary issue with the cast steel made from Bessemer's steel (that had been carburized) turned out actually to be embrittlement from phosphorus. The reason the Swedish steel performed so really due to the lack of impurities in the ore.

[@AHackOfAllTrades]

Superb synopsis of a historically important and interesting technology! More please!

[@patricknowak8292]

Thank you for a very good video and a nice overview of the processes. I am a metallurgical engineer working in the forging industry for the last 20 years and have been a blacksmith/bladesmith for 25+ years. Within the last few years I have spent a great deal of time researching this very topic and found the same information and references you did, though I have not seen Mr. Barracluagh's thesis, which I am looking forward to reading. There are a few details that might be worth clarifying: The Bessemer process was normally used to make low carbon steels because there was not much control over the process. Initially it was monitored by eye without any special instruments so if was very hard to stop the oxygen blow at just he right time to hit a desired carbon content. Converting 10 tons of pig iron into low carbon steel took about 10 minutes. The Siemens method was much better for fine tuning compositions because it took several hours or more and there was plenty of time to sample the liquid metal and make adjustments before pouring the steel into a mold. The method of melting blister steel was replaced much later by melting iron directly with a carbon source, but this practice was not adopted in until quite late. Harry Brearly, who was another instrumental Sheffeild steel man comments on this in one of his autobigraphies (he wrote 2) and notes that the blister steel would melt at a lower temperature than pure iron with a seperate carbon source like charcoal. This made it easier to achieve the desired melting temperature than to use the method that skips the blister steel. One final point of interest come from the book "The Arms of Krupp". The English really had a lock on the production of cast steel until the 1830s. At this time, Napolean sponsored a prize of 4000 Francs to whoever could replicate the English process. A member of the Krupp family was successful in doing that in the mid to late 1830s, but up until that time, pretty much all the cast steel in Europe and the US came from England.

It's an interesting perspective. As an Australian tool collector (Mainly made in England), this has been an obvious joy to watch. I have a MASSIVE antique hand cut rasp, over 2' in length, and a simlilar sized engineers screwdriver. I was walking towards the gate of the show where I bought them at, and a friend I know who was at the gate from a distance (Who also knew I was into medieval reinactments) thought I was dual wielding two short swords :) He freaked out until he came closer and realised I wasn't :p

[@nathanokun8801]

Thank you very much!! I took several decades to study how naval face-hardened side armor of cruisers and battleships was made from the middle-1890s (Krupp Cemented nickel-chromium armor steel in several varieties made by manufacturers in several nations (US, Britain, France, Germany, Italy, and Japan). I had to develop several parameters that isolated different steel properties from one-another to decide which were contributing to which final result, good or bad. The last WWII armor of this type used a standard 1.00 for their general steel "quality" prior to the processing of the steel into the final heavy armor plates, which were sorted by me into various levels of how good the armor was under various conditions. I used US nickel-chromium average armor-class steels made by the US firms of Midvale, Bethlehem, and Carnegie-Illinois in WWII for that part of the steel and then sorted out what was done to these steels (used for tank armor and the other softer armor class naval steels, too). Older WWI-era steels of this type were somewhat inferior, as can be imagined, due to the lower metallurgical expertise back then, as I found (with a couple of exceptions). However, as I said, I carefully sorted out each important parameter as to its effects on the final tested product and, for example, found some WWII Japanese experimental face-hardened armor (never used on a ship) to have the WWI-era steel quality but still ended up the best plates ever tested by the US or Britain after WWII (they never figured out why, to my knowledge!). The baseline steel quality of British face-hardened side armor used in its new WWII largest warships only came to 0.93, significantly lower than the US average 1.00 for steel quality, but the British armor turned out somewhat better than the US armor of this kind due to variations in the things like hard face thickness that the British did a better job exploiting. Thus, steel "quality" is more than just the internal metallurgy of the metal itself, but how it is processed to make the final product, which can make somewhat inferior steel give superior results, anyway. My phone number is 1-805-649-4952, if you are interested in my take on this huge topic.

damn, i kinda feel like calling. nice write up! this guy face-hardens

[@nathanokun8801]

@@-IE_it_yourself I started this hobby to make the armor rules in a miniature ship naval wargame based on an expanded version of the 1930s Fletcher Pratt Naval War Game designed by Ivan Travnicek as THE GAME OF ADMIRALS in the early 1970s. Good miniature ship game but had poor information on armor penetration rules. I had a GIGANTIC amount of luck on this and was able to more-or-less solve most of it, the face-hardened armor part all by myself since I found it had never been done by anybody in all of those huge navies, with they only knowing pieces of the puzzle.

[@jb-xc4oh]

As an interesting side note about Japanese steel from WW2, their Arisaka bolt action rifle was mocked by everyone as being junk made from inferior steel. In the 1950's an American gunsmith by the name of P. O. Ackley ran a series of tests on many military bolt action rifles to see which ones could withstand the most pressure before failing. Most actions would ultimately fail in various ways due to severe overloaded cartridges. However, the Arisaka action was the only one that remained intact and was returned to service by simply changing the barrel. No matter the overload the barrels would fail before the action could be destroyed, Ackley even used special high strength barrels but the Arisaka action did not fail, it was the strongest bolt action that Ackley ever tested.

[@boblewis5558]

Great video and very interesting. My maternal grandfather worked in the steel industry for many years making pig iron in South Wales. Years later I was a field engineer responsible for the ongoing maintenance of many of the Yorkshire steel companies' computer control systems including the bar mill at Thrybergh near Sheffield. That plant was using a process called concast (continuous casting). Steel was cast in a continuous flow from the furnace through a massive, water cooled "casting" tube that needed thousands of gallons of water a minute to ensure that by the time the steel bar exited the "casting pipe" it had cooled sufficiently to be able to be run out onto the cooling grid. The bar had to be robotically cut in a very short time as it reached the end of each loading rail. The multiple acetylene torches took sub second time (they had too) to cut the bar on the fly and liquid steel could then be seen running out of the "hollow" bar. Fascinating and mesmerising to watch but a realtime programming nightmare. Also the only time preventive maintenance could be done was during furnace reloads after all the steel had "flowed" out to form hot bar with a liquid centre AFAIK this process could be used to produce any kind of "cast" steel bar from mild steel to special steels but I have no idea of the detail on that.

[@halfabee]

Having been a toolmaker/fabricator working for the UK Admiralty Research laboratory. There is mild steel which is weldable without heat treatment. Car bodies etc are made from it. There is high Carbon steel known in the engineering stores as silver steel. Used for surfaces prone to wear. Knives are made from High Carbon steels. Damascus steel is layers of mild steels with High Carbon steel forged together. Cast Iron is a high Carbon steel cast. Which is not easily weldable. As it becomes hard as it cools. It is possible to weld cast iron with nickel as nickel is not affected by carbon. But the cast Iron around the weld is almost not machinable as it is so hard. Heating the Cast Iron to red heat and allowing it to cool down slowly in the furnace overnight will make the cast iron machinable after welding.

[@jjock3239]

I found your video by doing a random search, and found you talk to be very interesting and quite informative. The reason I was looking for an article like this, was that someone, in a recent conversation with me, had made a derogatory comment about cast steel, and although I knew what he was saying wasn't true, I couldn't explain to him exactly why he was wrong. This video has explained the history well enough, that wit this, and some other information, I was able to go back and amplify my arguments well enough to "educate" him on the benefits of cast steel.

Great video. Very watchable. We all learn and from the comments there may be a couple of minor things for you. No matter. Suggest (in the steel story) you look at the history of Swedish steel based in Gallavare (pronounced yallivare). I visited the town (in the Arctic circle) and the museum. They had a mining pan about 450mm wide and lifted from the sides (no long handle) The sign invited people to lift it. It was full of unprocessed iron ore. I tried and instantly thought it was bolted to the floor. With a little more oomph I managed to move it a little. The ore had a very high iron content so was bloody heavy! It was so valuable the first ore was taken out by dog sled! Then the British build a railway and then a port in Narvic, Norway, to ship it out (ice free) to Sheffield. The full history is fascinating. Must look at your videos on how to use your planes. Many thanks.

I liked it so much I subscribed. I hope to see more like this.

Great presentation! Really liked the explanations of the various steels, manufacture, as well as the history. Just having a too in your hand and using it for me is not enough, the question of who, how and why give the tool more value.

This is a really fun video, thanks! I'm a chef knife nerd who loves learning more about steel

So great to run into such a knowledgeable source of information. Thank you.

Thanks. A brilliant insight into history & the toolmaking industries.

This was a great watch; FWIW, you are really good at this! I'm a metallurgical newbie and this really helped. The way the history, the processing technology, the economics, the big names, and the products intertwine is fascinating. I'm still not clear on the difference between "tool steel" and "cast steel for tools" however! Oh, and by way of gentle advice, I grew up between Manchester & Sheffield in the UK and Mr Barraclough's name is pronounced "Barracluf"......I know, it's weird, and you're of course free to pronounce it however you like but I thought you'd like to know!

Great video, but do you have any more info on the image at 8:26? I believe those are 1890 Myers toroidal propellers which I was unable to find a picture of, got any source info so I can try to add it to the wiki page?

The photo is from a promotional book that Firth and Sons put together in the late 1890s. Unfortunatly, there's no info about the propellers, not even a date when it was taken archive.org/details/thosfirthsonslim00firtrich/page/78/mode/2up
