Forge heat treat on cpm d2.

For the more complex steels, send it out until you get an oven.

For the forge, just grab some simpler steels.

1080/1084 or 5160 or other sping steels.

I've had good results from 15n20 in my forge.

52100 does benefit from a more precise heat treat in an oven, buy if you have a decent eye, a thermocouple or a heat gun you should be able to do a passable heat treat.

Are you forging steel?

No I'm not forging. I mean, I could try forging. I started doing this because I wanted to be able to make knives out of high carbide steels, so I never really bothered to even think about forging.

I mean, I can buy something simpler and try. I honestly just don't think my heart will be in it.

I want to clarify I typed that post before I saw yours DeadboxHero DeadboxHero .

Your post did make me feel a little better about it. I wouldn't care so much, but right now I'm literally putting everything I have into this. It's my dream, and I kept putting it on the back burner because I would tell myself "I don't have this", or "I dont have that" I'm literally living paycheck to paycheck working in the drug addiction industry during the week, and sharpening and fixing up knives on the weekends. Then basically every waking moment I'm not doing that right now I'm trying this knife thing. So the costs that go into starting this thing seem so insurmountable. It can be discouraging.

Ok. I'll send it out. I have some cpm 10v I haven't touched yet. I was doing the cpm d2 first to see what would happen.

I guess I should decide what to ask them to do with it. I was going to shoot for 1400 for 10 or 15 minutes, and then austenize at 1950 for 20 or 30 minutes, then plate quench with the dry ice cooled plate quench vise, then put it into the dry ice slurry. Temper 2 times at 350 maybe.

So maybe ask them to substitute liquid nitrogen for the dry ice, and ask them to do that?

No worries,

You should listen to D DevinT

I learn lots of things from him, he has been making knives longer than the 35 years I've been alive and has pioneered lots of things like stainless damascus among many things and is very humble so he'll never brag about his accomplishments to let you know why you should take his advice.

Don't interpret his terse responses as being rude, thats not his intention and we are very fortunate to have him here sharing.

When you send out for HT you won't have the liberties to select specific temperatures but they will give you an option for a desired HRC range.

I'm sure some folks can recommend some heat treatment services for you.

I know. That's another reason I kinda was hurt, and defensive. Its corny to say this, but I look up to you, and devin, among others. You're one of the reasons I wanted to start making knives.

I've watched everything you've put out. I've read pretty much everything larrin wrote, I've seen his stuff on yt too. Before this post I would lurk on this forum too reading up what others have done with their steels.

If anyone knows anyone around houston tx that does ht. Lmk.

OK listen, you are human everyone here is human, if you see someone else do something there’s no reason you can’t do it either!
I’ve had plenty of times that I messed up or couldn’t get something in the first few tries, and I think to to myself that I can’t do it, but then I realize that others have done it SO I CAN TO! and then I work the problem and figure it out, I have not had a problem that I can’t figure out.

So, you’ve got this, especially if you love doing it.

Good luck my friend! and happy knife making.
 
Send your knives to JT for heat treat. He's knife specific and everyone raves about his quality.
You can find him here...
And while there may have been some terse replies, there's hardly a soul in this discussion with a motive other than helping you avoid mistakes we may have already made.

The microstructure is not your worry with D2 and a forge. D2 benefits greatly from a very precise temperature, for an extended time, 20-30 minutes. Short of that level of precision, you probably would have been better off with a simple carbon steel.
Wait for your oven, get some stainless foil and quench plates, and save your tool steels for when you can optimize their strengths.

This. You don't forge high alloy steels. Jesus Christ it's forged 5000x from the factory. If you don't have the equipment - spend the money or don't do it. Or do it and make people like me get more customers. You don't forge heat treat anything. 52100 is difficult with that chromium content.

Don't get me wrong. I was never arguing in favor of a forge over an oven for any reason. It was more me saying that I was using a forge, because I didn't have another option. Besides sending it out, but I'm stubborn, so I wanted to try myself.

No man you are not stubborn. You're learning. There's a difference. You want to learn. A lot of people don't. I've been doing this since October but my background in materials science chemistry physics etc. Makes the process go a lot faster. The only steels I would recommend TRYING to forge austenitizing and torch tempering are very basic carbon steels. The alloying is what makes the HT much more complicated on a scientific level. All you are trying to do is lock carbon into lathe and plate martensite (the latter is not what you want). I'm not going to get into it but Larrin from KSN explains things I think in a way that's easy to understand. I would highly recommend starting there and reading his book, John D Verhoevens "Steel metallurgy for the Non-metallurgist". And then start to spend money. Just my .02

Also the datasheet is just a guideline.

Peter's Heat Treating is probably cheaper but it's large vac furnace so. Not ideal temperature control but they'll cycle it properly.
 
Grain size could be better from what I saw there but it's pretty damn decent. I can tell exactly how it split. I'll let everyone else who wants to make money off ya back on here. Information should be free. It is if you dm me - I'll help you acquire some reading material that I personally have read and recommend doing so if you are going to be playing with steel. It's a lot simpler than most materials I'm used to LoL

No, Peter's isn't cheaper for small quantities. And they torch straighten warps.

Really? I didn't know that! LoL thanks for the information. I mean. It can be done with a torch I usually blue back shit so.

But yes I get your point. Im assuming I could ask for angle iron or something. Brad's a pretty good guy. **And no I'm not affiliated with them or adverting for them whatsoever** It's just where I have my shit treated in bulk cause evenheat takes half a year to arrive. Do have access to a lb18 but. It's not mine so. Also for those without Rockwell testers they'll test for you (I'm assuming we all have Rockwell testers)
 
Bos Heat Treating is still going at Buck knives, just sent 23 blades there. I usually go to Jarod for HT (especially with carbon steels oil quenched steels due to Bos limitations on length for those), but one of the blades in the batch was borderline for fitting into his cryo freezer. Texas Knife will temper everything to the same rockwell, (58-59 IIRC), so if you want a higher HRC on your blade, you are out of luck.

Oh my an opinion got someone butt hurt. Remove me. Please. This shit is no different than the rest of the retarded internet
 
Fine. One month for now. You can make it permanent by not returning...or you can decide to return and treat others here with the same respect you'd want for yourself.
