1.2519 is a chrome/tungsten cold work tool steel that is close to O-7. It is recommended for industrial blades, taps, dies, and reamers. typical composition:
C: 1.10
Si: 0.25
Mn: 0.3
Cr: 1.20
V: 0.20
W: 1.30
if you do some exploring, you will find the composition is almost the same as Hitachi Aogami1 or Aogami2. It seems about as easy to find. i guess you could call it super O-1 or 52100 on steroids. Roman Landes has commented that this is one of the finest non-stainless steels available for knives, that the tungsten and vanadium additions allow you to grind a very thin, razor sharp edge with extremely good edge retention(in the kitchen, not a steel for chopping wood or 3/4" manila twine)
I am going to try some as it appears to be a step above 52100/O1/A2 or CPM1v or CPM3V with a low temperature heat treat. why should the makers in the "Greater Eastern Coprosperity Sphere" be the only ones with super high carbon steel?
recommended heat treatfrom Bestar and Metal Ravne) I will probably use one of the pieces i ordered for testing
heat to 1475-1500F or 800C
quench in warm fast oil. one site also lists quench in brine. as quenched hardness Rc66-67
temper at 300F for 1 hour. cool. clean. Rc 65
temper at 350F for 1 hour. Rc63-64
I have found two sources:
Bestar LLC (770) 801-8855 american distribution site in Atlanta only size is 3/16" x 24 1/2" x 24 1/2"

if anyone has used this steel, any and all comments welcome
