How "old" is the blade?  Today most blades are being manufactured in
China -- China blade manufactures say they are spring steel with a
hardness in the low to mid 40's Rockwell C.  -- Not mild steel.  Older
American blades also would be some type of lower cost spring steel.
Roger's 1060 is not a bad guess, some might even been 1045, as it was a
very common steel. 
Ultra heavy duty blades such as used on bush hogs 1/2 inch thick by 3
inch width are often 5160.
