    Made by Republic Steel, this color film is one of a series called "Stainless Steel...The Miracle Metal". This particular film features Dr. Carl Zapffe presenting a lecture on the history and development of stainless. It dates to 1960. Stainless steel is a group of ferrous alloys that contain a minimum of approximately 11% chromium, a composition that prevents the iron from rusting and also provides heat-resistant properties.
    Opening: Republic Steel presents Stainless Steel, the Miracle Metal. Part 1: Historical Development (:06-:42). Dr. Carl Zapffe, a metallurgist (and also an internationally known physicist, engineer and chemist), looks through a microscope. He then starts to explain the film's focus. He holds a piece of stainless steel. he holds rusted iron. He picks up a piece of iron ore. He shows a picture of the piece inside a dead bison and a viking boat along with tin being used on an old table. A restored Viking boat at a museum in Oslo has original nails in it going back many thousands of years. Steel and carbon inside the nail is shown in detail (:43-6:27). A Damascus blade, the Damascus steel make-up is explained. Dr. Zapffe explains how we'll go back in time to discuss metal. He holds a meteorite in his hand which was found in Normandy. Going back to the pictures, the sectioned meteorite is shown. The 18-8 is explained. The numbers 18/8 refer to the percentages of chromium and nickel in the stainless steel alloy. The "18" refers to the chromium content, which gives flatware its rust-resistance properties, and the "8" refers to the nickel content, which gives it its silver-like shine and some rust-resistance (6:28-11:28). In 1797, a chemist in Paris is working on a new mineral, in 1798, the man shows off chromium. The father of chromium is Louis-Nicholas Vauquelin. He hammers chromium with a hammer and is splits (11:29-15:00). The doctor talks about how stainless steel needs certain minerals and explains what is required (15:01-16:50). A stainless steel piece under a microscope without the proper makeup. Another piece from under a microscope is shown and again the makeup isn't correct. Berthier's experiments are shown on a chart, it is explained how carbon kept causing him a problem (16:51-19:35). Dr. Zapffe stands in front of sulfuric acid, water, nitric acid, citric acid, acetic acid, hydro-chloric acid. Steel is placed in each one of these solutions, the Dr. pulls the piece out of each and explains (19:36-20:50). He moves back to a chart and explains how the percentages were off with trying to attain stainless steel. Goldschmidt's crucible experiments are explained in a diagram (20:51-23:16). Dr. Zapffe shows a map and explains where chemists who had pure chromium experimented, England, Germany, and the USA. He goes into great detail while standing in front of the map (23:17-26:25). Back at another board, the Dr. points out Carbon, Chromium, Iron, and Nickel. He explains other facts about these metals (26:26-28:49). Dr. Zapffe continues to summarize what the important chemists discovered (28:50-29:23). End credits (29:24-29:33).
    Republic Steel was founded as the Republic Iron and Steel Company in Youngstown, Ohio in 1899, and rose to become the nation's third largest producer. The company still exists as a subsidiary of Grupo Simec and produces Special Bar Quality (SBQ) steel bars.

    Unless you're a "knife knut," as we knife enthusiasts are often called, you're probably not aware that in the last 30 years or so, there has been something of a revolution in stainless steel. At least, a revolution in stainless knife blade steel. The three attributes one is always looking for with blade steel are resistance to corrision/rust, edge retention, and what is called "toughness," which is the ability of a blade to resist stress without chipping or fracturing. The difficulty is that there's always a trade off between those attributes, that is, making a steel more rust resistant tends to make it less tough or decrease edge retention; increasing edge retention will reduce toughness and/or stainlessness; improved resistance to rust comes at the cost of toughness or edge retention. With that in mind, knife makers have generally sought blade steels with either the best two out of three of those attributes, or ideally, steels that have a balance between all three. And for almost 50 years, the steel that had the best balance between edge retention, stainlessness, and toughness was 440C, and it was considered the best all-around steel for knife blades. However, beginning in the 1990s with improved ability of foundries to precisely control the amount of elements added to a steel alloy, and the ability to very precisely control the temperature of the heat treatment, or tempering, of steel, metullugists began producing steels that greatly outperformed 440C in all three of the categories. And just the last 10-15 years, a new industrial process for removing impurities by rapidity cooling the steel with liquid nitrogen has produced even better products. The upshot is that today, the best knife blade steels have edge retention and toughness around 200 to 300% better than 440C (which is still used as a standard for comparison), and are about twice as resist to rust and corrosion. Even "mid-range" quality blade steels have around 150% the edge retention and toughness of 440C, with equal or slightly better stainlessness. Jst to put the cherry on top, because of their uniform micrograin structure, the latest generation of these "super steels" aren't even that hard to sharpen, and you can put a hair-popping, razor's edge of them with only little more effort than it takes to sharpen up the old 420 steel of a Swiss Army knife. So if you're someone who appreciates a good knife but haven't bought one for bought one for a decade or two (like I was until a few years ago), I strongly recommend checking out what's on the market these days. For around $100, you can get a knife with one of those mid-range steels that will still be a better blade than anything on the market before 1995; $200-250 will get you a top of the line blade steel.

      I respect your Knife Steel Knowledge. I always thought the first was 440C (maybe D2 was the first) stainless in the 1980's (unless it's made by slave labor in China, they use 440A or 440B, who knows what type they truly are.) Next was D2 tool steel, I believe, then Aus 8, Now it's all about the powdered steels, like M390, S30V, and S35V, I recommend D2 for everyday use, and Bohler M390 steel for an explosion proof blade that will survive the apocalypse.Thank you for the useful information. cheers.

      @hatuletoh 2 роки тому +6

      @@justinwaters8679 Thank you. Sounds like you know your knife steels as well. I'm definitely not an expert, but I know a little of the history, and although chemists first produced the formulations around the 1920s, both 440C and D2 were perfected and went into large scale production right around WWII, which is why both of them (esp D2) are so ubiquitous today, despite still being pretty good blade steels: no company holds patents on them anymore. D2, as you said, didn't really begin appearing in knives until the 70s or 80s, when some custom makers optimized the heat treatment for it. Before that, it was pretty much a choice between 440A, B, or C if you wanted to get fancy; or 420, 410, or 414 for budget knives. In the late 80s/early 90s, a few companies, notably Spyderco, started using some Japanese steels like AUS-6 and 8, GIN-1, 3, and 5, and that eventually lead to them using even better Japanese steels like ATS-55 and ATS-34. ATS-34 is the Hitachi version 154CM, which is made by Crucible Steel, and once they realized the demand for it they began producing a lot more of it; consequently, you don't see many American knives with ATS-34 steel these days, but you sure do see a lot of 154CM (and CPM 154) blades out there. The Japanese VG-10 is still pretty popular in the US, though. I agree with your steel recommendations with a couple of addenda: the Swedish firm Bohler-Uddeholm makes M390, and it's damn amazing blade steel, but there are two other steels with pretty much exactly the same alloy formula: CPM 20CV from Crucible, and CTS-204P from Carpenter Steel. All three are basically identical, and perform identically if properly tempered. Secondly, if you're willing to give up stainlessness, my two favorite blade steels are CPM M4 and CPM Rex 45. They're similar, but M4 is a little tougher and much easier to find--I think some Spyderco sprint runs are the only knives with Rex 45 blades right now. In any case, both are amazing steels that hold an edge forever without sacrificing toughness, but they'll develop a patina and have to be protected from moisture. I live in the desert though, so too much moisture is rarely a problem for me. And lastly, the new king of knife steel is apparently CPM Magnacut. I have yet to get my hands on any of it, but, well...you can check out a summary by its inevntor over at the knifesteelnerds.com website.

    • @hatuletoh
      @hatuletoh 2 роки тому +8

      @@pitdog75 It always depends upon exactly what you plan to do with a knife, and how much you're willing to spend. The best steel for a small knife you're going to use mostly to open letters would be different from a big blade that you're going to put to hard use outdoors. And both edge geometry and a steel's heat treatment will effect its performance as much as what type of steel it actually is. All that being said and everything else being equal, my favorite steel for an edc knife has three names depending upon the company that makes it: CPM 20CV, M390, and CTS-204P, made by Crucible Industries, Bohler-Uddeholm--a Swedish firm--and Carpenter Steel, respectively. Again, those are three brand names for what is effectively an identical product, and it's arguably the best, most balanced knife steel available today. It's also the most expensive, so for a bit less money, CPM S30V, CPM S35VN, or CPM S45VN are almost as good. The next step down in price and performance would be probably 154CM, CPM 154, and Nitro V steel, but even two steps removed from the very best, those three are outstanding blade steels. As for a "meat knife," if you mean like a hunting/outdoor skinner-type knife, I think the very steel best is probably CPM 3V, followed by 52100. Although these days a lot of larger knives of that type are made from D2 steel, which is still a very good performer and is much less expensive than either 3V or 52100. If, on the other hand, by "meat knife" you mean something for the kitchen, I have to claim ignorance there--I don't know what most chefs would prefer. I can say, however, that I own a couple of kitchen knives made from a popular Japanese steel called shirogami or "white paper" steel, and they are excellent.

    This also explains why the steel body panels on some cars rust through in a few years when exposed to the air and road salt and others seem to have a natural corrosion resistance. One used cheap steel and the other used an alloy, not necessarily a stainless steel, one containing some nickel which increased common corrosion resistance.

    I recently started collecting knives and this helps give a better understand the myriad steels used for blades. There are various combinations of the ability to be sharpened, hardness, brittle or resilient, and corrosion resistance. No steel is perfect. There are steels that are designated as 8Cr13MoV which is 0.8% carbon and 13% chromium. More corrosion resistant but softer than tool steel. Easier to sharpen, but the edge may not last as long in use.

      That is because in 1962, Republic Steel suggested that the Steelers use the "Steel Mark" Logo on their helmets. That is what that logo is. U.S. Steel originally designed the logo, but turned the rights over to the American Iron and Steel Institute to be used to represent the entire American steel industry.

    We do actually know how to recreate the metal in those sabers, and the part about the slave isn't true. It you ran a red hot blade through something as chunky as a body, the metal would still be brittle as it went in, and then you would hit all kinds of different densities of tissue, most likely bone, which would destroy the crystaline structure of the metal that you just worked so hard to get. The metal needs to cool somewhat slowly and evenly to be tempered correctly, with no stressors being placed on it, such as the bending and twisting being thrust through a body would put it under. I took four years of metal studies in college, and this very topic actually came up in class once. My professor was a master metalsmith who enjoyed discussing oddities like this using science and practicality. I'm not saying this video isn't educational, but after hearing the narrator blithely toss those silly old myths around, I'm taking everything else with a grain of salt.

    • @Schtuperfly

    As a Pittsburgher, I'm glad to see the hypocycloids in the thumbnail and intro.
    But even though a great deal of civic pride emanates from that symbol, I must admit that it isn't "stainless". As great as the 70s football dynasty was, it was definitely fueled by the first widespread and systematic use of anabolic steroids in sports outside of the Iron Curtain Olympic programs.
    They were still pretty great, though, even if they were kinda cheaters. It wasn't technically against any rules.🤔😇🤣

    • @brianarbenz1329
      @brianarbenz1329 2 роки тому

      The term "stainless" replaced "rustless" as part of a PR drive to give steel a lighter, and more household feel in a time when people associated the product with the god-awful images of the steel cities choking in the mills' fallout. Also part of that image change was the creation of the tri-colored Steel logo (later adapted for the Steelers helmets).
