Industrial Mower Blades

[Vincent Price]

Was just given a couple industrial mower blades. Totally forgot to take pictures before I left this morning. The are from what i was told a heavy duty state road mower. They are about 4 inches wide that taper on one end, 10 inches long, and an inch and a half thick. They weigh about 12 pounds a piece. I found a parent pending number but no other markings to determine if they may be good hardenanable steel or no . Haven't spark tested yet. Anyone else have any experience with this type of steel or any ideas as to what steel is generally used for this application?

10 cents a pound at the scrap yard and buy new known steel.

Mower blades would be good to practice with, but I don’t recommend investing the time and effort to attempt making a good blade.
