The austenite grain size is generally very fine on all HSS due to the high amount of alloy which prevents grain growth, so yes. The carbide size is also small due to the mainly MC type carbides and the PM forming - however there is so much carbide that it is going to segregated into 5-10 micron clusters. There is also going to be a LOT of carbide. These steels can be a little tricky to sharpen because the edge can be very fragile, especially if you try to take it to a high polish.bearfacedkiller wrote:
Would this be fairly fine grained or not?
That chromium will go into solution (not be left as carbide) due to the very high soak temperatures used and thus you will find that :Would this be somewhat stainless even with only 4.75% chromium? What do cobalt and the other alloys do for stainlessness?
-this does not take a natural patina well
but it will not have enough chromium to resist strongly corroding environments and will have a mix of surface and pitting if left exposed to salt water and similar.
It would be similar to M4 for example.
In general :
-vanadium adds to wear resistance by forming MC primary carbides
-tungsten raises the secondary hardening and hot hardness by forming secondary MC carbides
-cobalt keeps ferrite (soft/weak) out of the final state (ideally is pure martensite)
Essentially yes, that is what it is made to do, replace those steels where they wear too fast or deform too easily. In knives though care has to be taken because at some point there is so much carbide in the edge that it will have issues being retained in the very thin cross sections of the edge and then it tears out rather than be worn. However this can be compensated by running higher edge angles and/or more coarse finishes as well.Would this behave more like the tool steels i'm familiar with only much harder?
In general I tend not to prefer full tang knives, it is a waste of steel to put it there as it does nothing functional (most people end up drilling it all out anyway).dgebler wrote:... how you are planning to have these knives assembled
I believe Kyley Harris (cKc knives) was the first maker to really speak out about very short tangs. His argument is that very short tangs on fixed blades are still much stronger than the same size tangs on folders.
If you have that as perspective it should be obvious that in general, unless you are snapping off folder handles on a regular basis then a solid pinned short tang will be easily strong enough.
I have not asked Jeremy exactly how he is doing it, he is talented enough to figure that out, I assume it will just be a pinned construction with a spacered handle.
