    Tempering 1095 blades to blue

    using 1095 you should be able to get those blades up to the next file of hardness eventually. Dont be afraid to soak for 5 minutes before the quench
  2. According to the specs I looked up: 4140 is stated as requiring between 0.37-.44% carbon, while 4130 is at 0.28 - 0.33% So the variance isnt as broad as I suspected, because I assumed a near overlap in specs, but still 4140 is not going to get much harder than 4130. Fully hardened Brinell hardness of 197 for 1430 to 205 for 4140, The published maximum hardness is just a lab testing, and not a real world spec. I did get one report stating a maximum Rockwell hardness of 54 to 59 HRC for 4140

    What is this?

    My money is on Hoof jack

    here ya go
  5. my complaint about using boiling brine is its ability to cool before vaporizing issues
  6. I dont think that a boiling liquid is a good way to quench
  7. there is not much of a difference between 4140 and 4130, and surely not 9 RHC points worth, in fact the specs over lap a bit
  8. there is a more involved thread on this at

    First puukko. No1 Mk3.

    I suggest buying silver to use, most of the time those old coins are worth more as coinage than silver.

    Katana Forging; Traditional

    I enjoyed it very much, but a few things were off. Too bad the narrator doesnt know the difference between heating and smelting (around the 6 minute mark) then the comment about straw ash being used to prevent over heating is a bit out there as well as the tempers the blade by quenching statement, It is possible its all translation errors made in the English version of the readers text.

    How to Harden Tin/Bismuth Alloy?

    People have tried to help you, but you wont help yourself, Keeping your project a secret isnt helping. You are clearly not qualified to be teaching anyone about casting anything. Some of us got the idea your trying to get us to do a school homework assignment for you, Since you wont cooperate and tell us anything, this thread is now closed.

    How to Harden Tin/Bismuth Alloy?

    I dont understand how you expect to teach these kids how to do a thing you yourself clearly dont know much about?
  13. Could be from improper tempering or excessive grain growth

    Forge Welded Pattern Steel

    Have you looked at the knife making section to see how others do it?. I will relocate this lost post there for you

    Raindrop pattern welded billet

    of course stock removal will remove part of the pattern, since its a surface effect much like ladder pattern

    Favorite steel for an ax bit

    thats why we weld it before thinning

    1095 heat treat problem

    that depends on the steel being used, not all steel forges the same way

    Novice question

    too hard? what are you using to try to sharpen it, and what didnt you understand about tempering in the heat treating sticky?
  21. From Knifemaking 2.0 Another thermal process to address is called subzero quenching. The purpose of a subzero quench is to force the conversion of retained austenite after the initial quench into martensite, allowing us to get the metal tempered, rather than allowing it to remain as the brittle untempered martensite if it were allowed to convert on its own. The sub zero quench is mainly applicable to high alloy steels. The home freezer is not cold enough for more than half conversion. Crushed dry ice and acetone can result in a temperature drop to about -170°F (-110°C). A quench with liquid Nitrogen will result in a drop to about -300°F (-185°C) and is used for many stainless steels. the down and dirty way is to crush dry ice and place in an insulated container, along with the cleaned blade. Pour acetone into the container and allow to equalize. This process can be volatile, so take proper precautions. Never add dry ice to the acetone, it can explode. Liquid Nitrogen has less risk. Remove the blade after 30 seconds, and allow to reach room temperature. Do not lay it down until reaching ambient temperature. A hanger for the blade is good for this. You must use gloves and tongs, and be sure to wear face protection and long sleeves. Do not allow the metal to contact any bare skin. Either method requires a follow up with a tempering cycle to address the newly formed martensite. Most high carbon blade quality stainless steels require a hardening process that is atmospherically controlled and done at rather exacting temps that are hard to reach and hold for the time necessary in a home forge. But it is not out of reach of the dedicated smith. UPDATE it appears that there is a better way to do this, read down the page for the link for details
