      " I like the cards with the numbers plainly written. " Inspired, possiby, by Bob Dylan's 1965 'video' that accompanied his song "subterranean Homesick Blues" He used flashcards to, perhaps, imprint the lyrics in our minds... Seemed innovative then, but probably had precedent in silent movies? It is, good, though, in that the data is front and centre, we're not distracted by a presenter turning to a board behind him...

      There have always been trade names used by steel producers. Some l can think of just from using them . Graph-Mo (O-6) from Latrobe Steel. They also had Graph-Air (A-10). Both graphitic tool steels with excellent machinability. Hy-10M. An oil hardening die steel. Mirralloy. A TG&P shafting steel. Carpenter 158 (P-6). Oil hardening mold steel also used for machinery parts. Then there are the non ferrous metals. Having both trade names and common names. The Ampcos, Mic 6, German Silver (copper-nickel alloy) and others.

    Great job! I worked with various alloys during my career as a product developer and with all the ones you clearly explained here. Most of the steels I used needed wear resistance and impact resistance. As with any metal, the more exotic the alloy, the higher the cost and lower availability. I used the Machinery's Handbook as a guide for material selection for years. As with many resource materials today, it is available in digital form as well as print.

    As a former toolmaker - we used a lot of Bohler's 476 tool-steel - came in black coarse finish - that had to be removed first. It gave off a very definite 'stink' while machining and bright purple shavings - quite unlike anything else.

    I've always wondered if you could use one of those Xray spectrometers that gold dealers use to verify precious metals on steel? Machines like the XRF spectrometer or the Sigma Metalytics verifier can not only tell you the percentage of gold, but the percentage of what other metals may have been alloyed with it. Most often copper, silver, palladium, or zinc. And in the knife world you hear all sorts of numbering systems. Plus the word magnacut steel gets touted as top of the line.

    • @andrewc9902
      @andrewc9902 4 หลายเดือนก่อน

      XRF will pick up the other elements of interest in steel such as nickel cr mo si mn and tramp elements such as S and P and others (with varying degrees of accuracy at low percentage levels) but EF cannot pick up the most important element carbon. Some of the tools will try to basically guess what grade of steel it is given the ranges of other elements but for example, if you had a 4145 steel the tool might guess it as 4150 or 4140, but it doesn’t actually determine the Carbon you need a different tool for that.

    You left out M tool steels. Usually called High Speed steel used as a cutting tool. Probably one of the most important tool steels out there. M2, M3, and M42 are common.
    As for 5160, it's spring steel very common in leaf springs (6150 in coil springs) and if you're into knife making, 5160 is a nice material for sword blades.
    Been involved in manufacturing and metals my whole life, although carbon steels are more on the rare side. We work mostly with steels like Alloy20, Incoloy800, CD4, Duplex 2205, H-loy C, 440C, Nitronic50, 316L, Ferralium 255, etc., although 9310 and 8620 are not uncommon for pivot pins.
    Bottom line, it's nice to see other people out there who work with their hands AND their minds to make things. 🙂

      A36 steel usually references the specification ASTM A 36 it was purchased to , not the particular grade of steel however, it’s usually around 1020 1025 steel. That specification is driven by minimum mechanical properties not so much chemical limits, so the manufacturers have some flexibility as long as they meet mechanicals . It’s about the most entry-level steel one would purchase unless they wanted something softer like 1010 steel.

    His use of the term ‘tenths ‘ for the determination of the carbon level is colloquially appropriate and correct.
    Except the high carbon Cr bearing steels all steels are under 1%of carbon content so by saying a steel is a tenth of A ( ie 1) percent he is saying it’s a 1/10 of 1 percent - which is how it’s understood. absolutely no one ever describes the carbon content in terms of hundreds of percent except maybe some chemistry professors. In some places it’s just referred to as ‘points’ such as 25 point steel. Ie 1025
    Another way to describe it would be to say 1025 steel is .25 wt% carbon

A lot of steels are just the tenths ~ .2.3.4.5 . obviously in the machining world tenths hundreds thou 10 thou is critical but the chemistry callout terminology, for steel is more relaxed because people are not mixing up a batch of steel on the spot , but just eluding to standard stock such as 1018.

      You know it! I have a pre production prototype which has served me well for several years.

    Awesome explanation. Thanks!! What's 12L14? Where does high machine ability steel and weldable steel com into the mix...?

    • @jasonlonontoolmaker
      @jasonlonontoolmaker  4 หลายเดือนก่อน

      12L14 is a low carbon, free-machining steel. The addition of lead aids in it's machinability. Machinable and weldable are terms to describe different properties of steel, and are used to describe different grades of steel, but are not part of a specification.

    These videos are great! Thank you! I wish I was young enough to actually remember all of this but I put these into my favorites. I was wondering when you were gonna get to 4340 because that’s what my SBC crankshaft is. I have a Bridgeport mill and Clausing lathe. I’m a home hobbiest and love it! My mind is everywhere lol. I love learning. I’d like to melt down some cast iron to make a follow rest one day because somehow they lost it. Almost bran new 80’s machine. 12X40 VS-12. It has zero wear luckily. It still has the original belts on it too. I got lucky. I want to learn hardening steel and aluminum. Do you also work with aluminum? I think these kind of videos will do really well

  • @RobWhittlestone
    @RobWhittlestone 4 หลายเดือนก่อน

    Very interesting. Is there a list somewhere of all the first digit steel type designations? Knife manufacturers sometimes indicate the steel used in particular knives, it would be interesting to be able to decifer these. Similarly, there is a a designation system for aluminium alloys. Is there also a deciphering table somewhere for that?

    • @jasonlonontoolmaker
      @jasonlonontoolmaker  4 หลายเดือนก่อน

      Here is a link to a list of the first digits of the AISI / SAE carbon and alloy steel system I talked about in the video. www.theprocesspiping.com/wp-content/uploads/2017/12/sae-aisi-table.png

    Interesting and consise presentation, thanks a lot. I'd like to go deeper into this. Are there any (official) tables / standards available that provide detailed information on chemical composition of the grades, based on these 4 digits? I mean that just a glance and some memory should be enough to see that this grade will be fine, and the other one won't work. Getting through the masses of datasheets with % range of each element is not what I need or like. Any hint, please? Or how to ask google to get the links quickly? Thanks in advance.

    Thanks. Very informative. Curious though, I buy A36 steel for various projects. What does the A and the 36 stand for. Also, what is AR500 steel?

    • @boblawson1006
      @boblawson1006 4 หลายเดือนก่อน +7

      "write the grade on the steel..." Assumes your workmates can read... I marked a piece of material "tool steel, do not use" quite clearly, but one of the fitters ignored, or failed to read the marking, cut the material up to use as spacers... Then complained he found it hard to work... He'd selected it because it was a short piece of material, easy to carry to the saw... that it was expensive didn't matter to him...

    I think you'll find the main 'element' in carbon steel is 'Fe' Iron - the carbon content rarely goes above 1% and only up to 2% for knives and specialist cutting tooling.
