talonite

No, if I recall correctly. Talonite gets its hardness from the carbides in the matrix. It's a cobalt chromium alloy and doesn't contain any iron. Because of that it doesn't respond to conventional heat treating methods. At least that's what I remember reading when I had a passing interest in the stuff a few years ago.
 
Elkins45,
Thanks, that is kind of what I thought too. I also noticed that some of my talonite blades are very soft and bend easily but this does not bother the ability for the blade to cut.
 
tallonite is hardened it is age hardened, mid 40s Rc is as hard as it gets. elkins45's is right the carbides do all the work. Can I ask why your concerned? maybe I can give you some more info
 
I have to work in forest for couple months and it rainy here in Thailand. I will choose small fixed blade for edc and talonite is my first choice. I'd read many about talonite, good ability to hold the edge, never rust, can't chop. But I confuse why hardenest is low hrc. And should I use talonite knife for edc?
 
I thought the matrix of Talonite was lower 50s HRc. In any case it's fairly soft and the edge tends to roll over.Between that and the expense people lost interest in the blades.
 
Tallonite stellite 6BH, is composed of a cobalt matrix which is not very hard, about 44-49 HRC, and suspended carbides. Tallonite gets its wear resistance from the massive amount of large suspended carbides. Tallonite will take a rather toothy edge that is deceptively sharp. It excels at cutting soft materials, like flesh, or cardboard but since it is not very hard the edge may roll on a hard wood, so chopping is out, but edge rolling is much easier to fix than chipping. So for a small slicer tallonite is awesome, it would be O.K. for an edc, but I would probably take along another blade.

here is a data sheet http://www.hpalloy.com/alloys/brochures/HPACOBALT6B.pdf
6B, and 6BH are the same alloy H stands for hardened, age hardened.

interestingly Tallonite will not corrode. ever. (well it will if in sustained contact with highly concentrated acids, that would probably kill you before you noticed any corrosion) it is not magnetic like steel, and it's coefficient of friction is much lower than steel-its slippery. Oh and its really expensive both raw material cost, and cost of working with the stuff.

does anybody know if Carbide Processors still sells the stuff?
 
Cavitation erosion ! I knew I had involvement with those alloys back in time !
 
Why not something like CPM154? Seems to be a more logical choice for something getting used and is stainless. Should, with a little maintainance, be fine in a humid/wet environ.

It also seems to form a strange rubbery purple coating when you use it to cut through a banana tree. This leaves no permanent mark on the blade, just thick coating, I've seen it on some other alloy steels as a film, but on talonite it builds up extremely thick in a short period.
