I found this big old disk for practically nothing at the junkyard. I cut of a couple teeth off and got rid of the welded on cutting edges.
Cut small strips and heated to non magnetic, quenched one in oil and other in water. File test is good and pieces snapped when put in a vice and bent with pliers.

You can see that the unheated part is bent and the heated quenched part has snapped.

You reckon this is good enough steel for a blade? Grain look ok?
Was thinking of making a pole axe / halberd as an experiment. Maybe do some differential hardening on the edges only.
