C 0.46, Mn 0.4, Si 1.0, Cr 8.0, Ni 0.3, Mo 1.3, V 0.4

Working hardness 55 plus

I like it a lot and have made several blades by grinding them in the hard state but if I can find the name for the steel I can anneal them and actually drill and saw and grind like a normal person. Can't find the appropriate resource on the net.

If you can help, please do! Thanks. Check out the chrome and moly!

Don't have to know the name of the steel to anneal it. This procedure will work for just about any alloy:

Hold at 1275 for 2 hours, cool at the rate of 25-50 degrees per hour to 1000 degrees, air cool from there.

Looks a lot like H13, except the chromium and carbon are too high, and the vanadium is too low:

I've saved a big .pdf from Timken Latrobe with like hundreds of steel compositions listed. (I'd be happy to email it to you if you'd like to look through it in more detail.) I thought sure I'd found it until I got to the nickel column... But so far A8 Modified (they call it TLS Chipper Knife) is the closest I've seen. Nominal elements are listed as: C 0.5, Si 0.95, Mn 0.45, W -, Cr 8.0, V 0.45, Mo 1.3, Ni -. How much does that .3 Nickel affect things?
 
This grade is what is more commonly referred to as a Chipper Knife steel and is used extensively in the lumber/paper&pulp industry. very tough wear resistant grade.
Soft annealing - heat up to 1600 degrees F -equalize - then cool in furnace @ 25 degrees per hour down to 1200 degrees F then cool freely in air. This annealing cycle is time consuming so it would be Ok to heat to 1600 degrees -hold for one hour then turn off your electric furnace and let the steel cool down inside the furnace to room temp.
 
Thank you thank you thank you! I knew I could anneal it but it's the hardening and tempering that I run in to trouble with not knowing the alloy designation.

Possum please send me that file wnease@hotmail.com

Thanks again!
