OK ty
I found this on another forum.
"it's abrasion resistant steel . it's used for plow blades and such. they add Boron, Manganese, Nickel, and Chromium to make it wear resistant. this also complicates things when you want to "work" it or, weld it."
Sounds like it would be very difficult to forge it in the first place.....but Iam new to this so it would simply be a guess.
