You guys asked about ats-314, so i found out... it will also be updated on z-knives steel chart soon too (i shared this with him as well)
Carbon(C)1.0
Chrom(Cr)15
Molibdenum(Mo)1
Vanadium(V)0.1
Cobalt(Co)1.4
We have it in the ryusen fukakuryu series at 61hrc. It was mostly hair shears before, but after testing, they found it just slightly behind sg2 in terms of edge retention, but much better than vg-10... in some tests it was on par with sg2. Its also easier to sharpen and gets sharper than vg10, without being much more brittle (slightly though). Sadly, its an expensive steel... up there with many other powdered steels like sg2. Now I've had a bit more time with it... sharpening, in use, etc. I've come to enjoy it a lot.
They said this:
ATS-314 is a stainless cobalt alloy steel. To a carbon steel, Chrome is added to increase wear-resistance and Carbon is added for edge taking ability. This is a type of stainless steel Hitachi steel co. developed. By adding cobalt to the alloy, it can have a great hardness as well as wear-resistance. It is, however, a very expensive option and also difficult to work with to make knives. However, we believe this steel is a well-balanced steel for kitchen knives while having a structural stability, toughness, sharpness, wear resistance and stainless.
