A11 and CPM 10 V

#1

Post by Skidoosh »

Please clarify my understanding. The Micromelt A11 and CPM 10V are essentially the same steel. One made by Carpenter the other by Crucible, correct? My A11 mule is the same steel as CPM 10V?

They are very similar. There are a few versions of A11, aside from the Micromelt A11, but they are all virtually identical. Unless someone does a cut test with these steels, it should all feel the same between 10V and A11.

K390, which is supposed to be an "upgraded" A11, is the most different in composition. I still doubt anyone would notice a difference between any of these, as far as edge retention goes. How they sharpen, what kind of edge they take, edge strength, and corrosion resistance, might be the only noticeable differences. I have heard that CPM 10V is less prone to corrosion than K390, and I would assume the 3 versions of A11 on this graph, would be similar to 10V, given how close their compositions are.

I know you did not ask about the other versions of A11 or K390, but I got carried away. I blame the extra free time many of us now have. :D

Essentially, yes.

According to Michael Christy - K390 is just slightly more tough at the expense of ultimate edge retention
