Elmax tempering question

[donttrustthepig]

Hello everyone, I've been a member here for a while but this is my first post. I have a knife I would really like to make in elmax. I read that it like a cryogenic temper and how it gains you a few RC points, but is the crying treatment really needed? I couldn't find a straight answer on other fourms. Thanks in advance

I made two blades from Elmax without cryo treating. Elmax gains hardness about 60 HRc after properly HT. This is based on material specification. Users never have had problems with them.

Real gains in performance require complete understanding of the process otherwise you won't be successful.

 

[chumaman]

try to make a conclusion

 

[Jesenius]

These are very subjective tests. For example, Trapper II have DLC coating other two have not. 002 Lacko test was performed by hand, other two on jig.

 

[chumaman]

the conclusion is that those who are unable to do proper HT as they should always have excuses and justifications
example ... you mean that D2 is the same cryo and non cryo HT

 

[jdm61]

For Elmax, you need cryo for maximum performance and that means LN, not dry ice. That came straight from the BU rep at Blade.

I have no idea why You wrote about Yourself... anyway: I never wrote about subzero vs. non subzero are same, that is Your mystification. I only wrote about non subzero is good enough for ordinary use, that's all.

Your rationalization ...... 'good enough' and 'after properly HT' Talk more about how 'good' you are to present your work
I do not have to and do not want to agree with that

First off thanks for the feedback everyone, So essentially what I'm drawing from this is that you don't need a Cryo treatment, but to get the best performance from the steel you do need it.

The blade will cut without heat treating, but to get better performance from the steel you do need it. What level of performance are you satisfied with?

If you plan to sell the knife you should deliver the maximum performance and best craftsmanship possible. If the knife is for personal use, and you don't cryo, you will always wonder what the knife could have done.

Well said

1. I am hobbyist and no pro. When I turn to pro I probably will do cryo on my blades. For now it's not economic for Me.
2. I don't need present My work to You or here in general because it is useless. If You don't understand, go to point #1.
3. Go to point #1

I do not have to and do not want to agree with that

As You wish.

For others: links to pictures on some of My work You can see in My profile.

stupid is that I spam the topic but such bad examples as yours is too much in the knifemaking.
It is not a hobbyist, a professional or a company.... but presentations steel and deception of the public
In the profit race, everything has already been seen
your ego does not give you a clearer picture

Well, I was always curious to know what forces people to write words like You wrote here. I didn't discovered it and probably never will. I'm not a psychologist but You have to be very unlucky man if You need to go here and wrote this very "deep" sentences. You surely make beautiful knives besides Your criticism, please show Your work to us!

Append: You are spitting on My work and then You post here this?

It's a misunderstanding that knives that benefit from cryo do so just because of the hardness bump. While there is something to that, that hardness bump represents the reduction of soft weak structures in the steel that play hell with edge stability. Two Elmax blades at the same hardness and identical geometry may not perform the same, it depends on these structures.

Elmax needs cryo. If you can't do that you should select a different steel. This actually applies to most of the complex steels. Selecting a high end steel and doing a second rate job on the HT defeats the purpose of using the high end steel. Elmax can perform very very well, but there have been enough slack makers and manufacturers out there doing a poor job in the HT that it doesn't have the reputation it could.
