I don't know anything about this steel. Could somebody fill me in on how well this stuff takes and holds an edge?

Thank you very much.
 
This is excerpted from a data sheet for the steel (linked below), from Crucible:

http://www.crucible.com/PDFs\DataSheets2010\dscruwearv12010.pdf
Carbon 1.1%
Chromium 7.5%
Vanadium 2.4%
Tungsten 1.15%
Molybdenum 1.6%

"CRU-WEAR is an air-hardening tool steel, heat treatable to HRC 60-65. Designed as an upgrade to D2, it offers better wear resistance, greater toughness and higher attainable hardness. Compared to the chemistry of D2, (D2 = 1.55% carbon, 11.5% chromium, 0.8% vanadium, and 0.9% molybdenum), CRU-WEAR has less carbon and less chromium, but more vanadium and tungsten. Both D2 and CRU-WEAR contain carbides for wear resistance, but CRU-WEAR has more vanadium carbides than D2. Vanadium carbides are harder than chromium carbides and are much more effective in providing wear resistance. Because CRU-WEAR contains less carbon than D2, its overall carbide volume is lower, making it tougher than D2. (Note: Although CRU-WEAR contains fewer total carbides, it has more of the type of carbides that are most effective for wear resistance.) CRU-WEAR’s higher attainable hardness results from the fact that it contains sufficient tungsten and molybdenum to cause a secondary hardening response, (up to HRC 65), which does not occur in D2. Finally, CRU-WEAR tempers at a higher range (900-1050°F) than D2 (400-600°F), so it is more compatible with a wide variety of surface treatments."

"Upgrade to D2,...offers better wear resistance, greater toughness and higher attainable hardness."

I hadn't heard of it before. But based on that criteria alone, it sounds like pretty good stuff.
 
Thanks guys:thumbup: I am (Hopefully) getting cru-wear mule in a trade and was interested in how the steel performed. Seems like it's a very nice, tough steel. I will have to ask the guy i am trading with to test the hardness with a file before anything happens. Thanks again guys.
