MT46S MagnaMax SE Testing Thread

[Sterling454]

when will we know the composition of this steel ?

We removed the composition of the steel from the website. Larrin said that; 1) our listing did not include all of the elements, and 2) We should wait to list the composition of the steel until a formal listing in published publicly.

Sal, does that mean you would prefer that I not share the composition contained in the insert included with my MT46P?

Hi Sterling,

That is correct. Larrin said that the chemical composition listed earlier was not correct. We've been asked to remove the listings until we can get the correct formula from Larrin.

sal

Thank you the confirmation, I'll keep it to myself.

Wow, this is quite interesting. Would this then mean that the performance out of this Mule is not to be expected out of future MagnaMax models?

With the ongoing interest in this Mule/MagnaMax in general, would/could we see another Mule Team run once Erasteel gets their production of MagnaMax underway, with the proper chemical composition?

[Larrin]

Crucible produced two heats of MagnaMax. Spyderco used the second for the "MagnaMax" mule. The more limited "Proto X" mule used the first heat. There were some small modifications attempted between the first and the second. These were prototype heats for analysis to determine if the steel hit the property targets, and the remaining steel was sold to those willing to experiment with it.

There will be minor differences in composition between the Crucible heats and the final material made at other mills, though there are also minor differences between any two heats made by the same company.

This clarification is much-appreciated @Larrin! Thanks for everything you're doing for blade steels!

[Evil D]

@Larrin Correct me if I'm wrong here but wasn't there a hardness difference between the MagnaCut Mule and the later production folders? Or was it even after the folder production started?

That would be a question for Spyderco not me.

@Larrin , is the composition listed on the paperwork with the magnamax mule correct? If not, can you tell us the specific differences?

I can discuss the composition after the patent attorney lets me know the patent application has been accepted.

Anyone have any stats on the HRC of these? Given the info released by Larrin so far, I'd be interested to know what it is. looks like 2nd batch has the potential to dominate the charts if at the right HRC, at the cost of a little corrosion resistance.
3 days daily use now. Looks like when I got it, granted, it's just been a cardboard destroyer.

[Sterling454]

It's so nice getting this info from the horse's mouth!

@Larrin, I eagerly await a full YouTube video from you diving into MagnaMax in depth. I'm also really looking forward to the next additions to your charts on KnifeSteelNerds with MagnaMax and Pop's ProCut. I, among many others, regularly reference your data and am so thankful for your contributions to the knife community.

I tested mine under the scale area and got 64.9 and 65 on the nose. Not sure about everyone elses.

Thanks Larrin. My reading on this seems to lead me to believe that the second "MagnaMax" heat for this Mule release was unintentionally quite a bit further out of compositional specification within the tolerances that were aimed for. Is this so, and why the composition has been redacted?

*Edited for clarity.

*Edited for clarity.

Larrin has stated elsewhere that Magnamax heat 2 was out of spec for the steel. Instead of the additional chromium requested, there's +0.25% more carbon. Seemingly resulting in higher toughness at equivalent hardness than heat 1, and higher hardness at equivalent austenitizing temps (@2200f heat 1 hit approx 64.5 HRC and heat 2 hits just over 66HRC). At 64.2 ish HRC heat 1 hits approx 6t-lbs toughness and heat 2 hits 7.7ft-lbs ish. I'm eyeballing them where there's a decimal though. and Larrin also estimated the corrosion resistance to be in the range of M390, S45Vn and Elmax which was less than what he was going for. Further info is on the patreon it seems, but I'm going on what has been said publicly on youtube.
I guess to sum up, traded better toughness/edge retention for corrosion resistance

I’ll take that trade off

Honestly? Same. In my *uneducated* opinion it seems in this state to be a tougher (for equivalent HRC) and more stain resistant K390. Whereas the goal is to be at k390 performance with Magnacut stainlessness.
I don't really chase stain resistance in my knives. So for me this lands in the sweet spot

Thanks, Sal! Appreciate it!

[Fireman]

Thanks Dr Larrin. What I’m hearing is that people who receive these mules are really in the beta testing and that is an awesome privilege we get to test the steel to give feedback. Thank you so much Dr. Larrin/Sal. What I’m also hearing is that the first melt was probably smaller and will be hen‘s teeth Valuable for collectibles and the second melt will be just slightly shy of hen’s teeth for collectors and should be valued, but still appreciated and tested, but we truly have something special with this Mule Team. Thank you so much!!! Now to get to testing once my scales are finished

Crucible produced two heats of MagnaMax. Spyderco used the second for the "MagnaMax" mule. The more limited "Proto X" mule used the first heat. There were some small modifications attempted between the first and the second.

So what I am reading here guys, is I need to go ahead and buy the MagnaMax SE off ebay so I can have my way with it.
