dps9999 Posted November 12, 2015 Author Share Posted November 12, 2015 oh also i am new to this so bear with me do i need to anneal or normalize the steel from where its at now before i harde or straight to harden.....is so does one need to be done right after other (same as above) Quote Link to comment Share on other sites More sharing options...
Justin Carnecchia Posted November 13, 2015 Share Posted November 13, 2015 Normalize 3 times then harden, temper immediately after hardening. Not sure what the exact heat treat specs would be, personally I go just above non-magnetic, hold it a bit and then quench in oil. May not be getting the maximum performance from the steel, but it makes a decent blade. For your tempering temperature, you will need to experiment a bit to find the best balance of hardness and toughness. Quote Link to comment Share on other sites More sharing options...

If I was a gamblin man, I'd bet he was referring to one of his lengthy posts teaching knife making. He goes in depth in each of them and even with the pictures missing they are still a wealth of information. Quote Link to comment Share on other sites More sharing options...

Steve Sells Posted November 13, 2015 Share Posted November 13, 2015 how about the sticky posted at the top of this page? One would assume if you wanted to know about heat treating and there is a post pinned to the top of the page on that subject, one would have taken the time to read it. I sure aint going to retype it every time a person wants to know... Quote Link to comment Share on other sites More sharing options...
dps9999 Posted November 13, 2015 Author Share Posted November 13, 2015 thanks w pearson...........steve i dont see ANY sticky pins by you on the top of this forum page the only 2 that are there are "blacksmithng on history channel by frosty" and "new knife maker by rich hale" not saying its not on some other page but if you click knife making from the main page there is nothing by you or with a heat treating title ...now if wpearson is right with his link (havent click it yet but i would tend to think its right ) your post is not at the top of this page it is in another section of the forum wich honestly i didnt even bother looking at that section as another forum i was on a while ago had a section similar to that and it was all about people looking for knife making classes they can go to locally wich i already know there ar none near me so again.... quoting you "how about the sticky posted at the top of THIS page?".......not on this page Quote Link to comment Share on other sites More sharing options...

Steve Sells Posted November 13, 2015 Share Posted November 13, 2015 this entire section is about heat treating for blades, !!! I give up trying to help. Quote Link to comment Share on other sites More sharing options...
dps9999 Posted November 13, 2015 Author Share Posted November 13, 2015 ok steve your right ill admit when i am wrong i have been reading entirely to much i thought i posted this in bladesmiting/knife making .....sory didnt want to upset you can some one ansswer me one question...with a 1080/15n20 is it nesssacary to normalize 3 times before hardening i ask because i keep hearing that it will cause alot of scale and crap on the blade wich i dont want to deal with unless i have to as the blade is already shaped and a general primary bevel put on i dont want to have to sand or grind so heavy it messes that up Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted November 13, 2015 Share Posted November 13, 2015 Have you tried heating it in a piece of horizontal pipe with an end closed off and a good layer of real charcoal on the "floor" to cut the O2 down? Have you tried heating it wrapped in heat treating foil with an O2 scavanger? Quote Link to comment Share on other sites More sharing options...
dps9999 Posted November 13, 2015 Author Share Posted November 13, 2015 no i havent done any HT with this blade yet,, i keep hearing different opinions some say that normalizing is needed some say its not and then i hear that it causes ALOT of crap on the blade. i mean i know how to controll the atmosphere (as i did creating this blade) you think that will be enough. maybe brushing it when it comes out. i dont mind a lil i am going to have to deal with that no matter what but i just dont want it so bad i end up screwing up the shape tring to get it back off....also should i clean between each step...normalizing ,hardening, temper....this is the first time HTing in a propane forge Quote Link to comment Share on other sites More sharing options...
Justin Carnecchia Posted November 13, 2015 Share Posted November 13, 2015 The temperature used for heat treating shouldn't create excessive scale, especially given the typically short time span involved in heat treating. Just try to heat the blade evenly, and don't go to far above non-magnetic and you'll be fine. Quote Link to comment Share on other sites More sharing options...
gearhartironwerks Posted March 25, 2016 Share Posted March 25, 2016 Cruising around and coming on this late as usual, but have some suggestions: Using a propane forge to ht, buy a thermocouple and a pid temp reader to manually control the temp. A needle valve for your gas line will refine the process. Prior to the quench, I like to thermocycle 2-3 times to refine the grain, then I normalize for stress relief. This seems to minimize warping. Soak time is important. I like to heat to 1500 and soak 5 min prior to quenching, especially with 1095/L6 combos. 1095 is a hypereuctectoid steel and is not very forgiving. By doing this, I consistently get 64 hrc, then temper back. There are no shortcuts for consistency. I tried. John Gearhart Ironwerks Quote Link to comment Share on other sites More sharing options...
