@Barmoley All excellent points I just wanted to expand a bit on the ideas because bringing this wear resistance discussion out of controlled testing and into the real world things look a tiny bit better for White class steels and considerably more bleak for AS and 1.2562 (the other tungsten alloy steels have a decent toughness boost which helps them in comparison to the white class steels).
The testing abrasive used is a very common abrasive in food although in higher volumes.
As far as a softer abrasive is concerned I would expect to see steel with higher cementite volumes perform better. While the tungsten low alloy steels would benefit less due to lower volumes of cementite. If anything it's possible that you would start to see something like 26c3 outperform AS in terms of wear resistance. You might even see 26C3 bounce up to the same level as 52100 although this somewhat depends on the nature of the relationship between abrasive and carbide hardness (something talked about extensively in sharpening).
The only scenario I could see the tungsten alloy steels perform better is if the test moved to a harder abrasive where the cementite became even less relevant. But even then the difference would be marginal the low alloy tungsten steels have MC carbide volumes of 2% or so max. This is rather interesting with apex ultra coming down the line as it seems that steel gets its wear resistance in a similar fashion to 52100 (through enrichment of the cementite) rather then any sort of MC carbide formation.
