Press Quenching 01 Steel

As expected, the 3" x 2" x .25" Thick test piece did not fully harden.

Austenitizing temp was 1460F, soak time @ temp was 20 minutes.
Pressed between two large, 2" thick Al plates @60F, in foil packet.

As quenched hardness was Rc36

Sample was subsequently reheated at the same temp/cycle, and oil quenched to Rc63 to verify the steel type.

If I had some thin stock, I would try it again, but, I think the results might be only slightly better.
