AEB-L

I have found a stress reliving step really helps with warp issues. Was looking at Peter's heat treat yesterday and they now perform, and charge, a mandatory stress relieving step for AEBL and other similar warpy steels.
 
Thank you Lorien Lorien , but I already have the tools you suggested and am completely capable of using them and regularly do. Joseph Bandeko Joseph Bandeko & D DevinT provided the useful reason and terminology I needed for direction so I can use those references effectively & efficiently. I haven't been at this since 2005 like you have, and if the answer is "just look at KSN" for every question then this wonderful forum wouldn't need to be here. We all start somewhere, and a <10 knives made schmuck like me probably isn't going to know the finer points of difference between European steel mills and their proprietary recipes. YMMV, of course.
 
This reminds of a teacher I had in elementary school. She would tell me to look it up in the dictionary if I didn't know how to spell a word. "How in the goddamn hell can I look it up if I don't know how to spell it?", I asked, or something like that.
Now we are spoiled by Google inferring what we mean even if it's wildly misspelled.

You probably need a mentor. Forums are a good place to start but makers have differing opinions about lots of things which makes things difficult.

We’re lucky that Larrin has done all of that research and has written about it for the benefit of the knife community.

I've been a member of Bladeforums since 2005. I've been making knives for about a year, and have made only a couple dozen at that.
Now, I don't know what kind of tools or knowledge you have- in fact, I don't know you at all. I'd thought that suggesting checking out KSN would be helpful. You told me it wasn't helpful. At that point, in retrospect, I should've left this party instead of being butt hurt by having my advice thrown back in my face.

I went to KSN and typed AEB-L into the search bar which brought up a lengthy article that addresses your question somewhat. I used that article as my launch pad not long ago for better understanding this steel and its analogs.
I then typed 'difference between 13C27 and AEB-L' into Google and found more links that detailed specific differences.

Anyway, it doesn't matter and I don't mean to steer this thread off a cliff. I'll bow out now.

I’ve thought about doing this, just not quite sure what protocol to follow, I’ll have to do some more research on the matter, perhaps the wonderful D DevinT or Larrin Larrin have some recommendations on the matter?

Wish I had a mentor! Instead this teenager has to do a ridiculous amount of research to make up for it (well kind of makes up for it), lol.

Sure it would be helpful checking out KSN .I read over and over some article there . BUT to get answer on that simple question he asked ALL of us should need to make search on KSN to get that same answer . The question was asked here and the answer should be HERE , do you agree with that ? It is obvious that frequency of visits of this part of the forum has decreased. This is one of the reasons for that. A man asks something and what he gets in response, go there and see. Instead of opening topics for entertainment / I hate I love / to increase member visits , you could have answered his question to which many of us would like to read answer .............. Sorry for of topic !

"Delivery is everything" is an old catchphrase that can be heard in many disciplines, i.e., comedy, marketing, advertising, communications, etc..
It simply means that how you present something is as important as the content itself. Present it wrong and the content is far less likely to matter.
It is especially pertinent in today's online world.

when in doubt, use 1200F, and furnace cool, usually overnight.
bring furnace to 1200 F, put the blade in, turn off the furnace in an hour or so, goto sleep, wake up the next morning to a stress relieved blade

I’m not quite that stupid, I’m just asking who it was addressed to.

I did not in any way suggest you are stupid and I find it unnecessary for you to say. I was answering an obviously vague question. Our ages are far apart; I had no idea if a young person would be familiar with the phrase or not, so I explained its meaning. If that offends you, ask clearer questions.

My comment was an observation on the tenor of the thread, saying that a comment intended as sincere was not well understood because of its delivery. It could just have readily been a wiseass comment. It's a reminder that words on social media are best when delivered with care.

Hope that answers your question. Merry Christmas or Happy Hannukah or whatever Season's Greetings apply to all! :)

Not offended at all!

Merry Christmas to you as well! And to everyone else for that matter!

For stress relieving I use a 500 ramp to 1200 degrees F and then soak for 2 hours, oven cool. I find it helps with not only AEBL but also thinner PM steels that might like to warp. I perform the stress relieving step when I have finished working on knife blank and it is ready for heat treat.
 
Sounds like the consensus is to soak at 1200 F and slow cool, my only question to this is, how will that effect the microstructure and thus change the final austenitize/soak etc? Or because it’s only 1200 F will it even change the microstructure at all?
Again thank you so much to everyone for helping me!

There are many more knowledge than myself but I think 1200 F is low enough not to effect any of the steel properties. Most all steel data sheets mention using a similar stress relieving step if needed.
