Nuclear submarine hull steel (HY-80)

One thing I meant to do yesterday — I talked about the various price of materials, the pound of weight saved in different industries, and I was going to hand around — [Tom produces a piece of steel.] this is a piece of steel from General Dynamics. It's HY80, a high-strength submarine hull steel, and it's a weld they gave me when I was down there about 30, 35 years ago. It represents two-dollar-a-pound type of material. You can make nuclear submarine hulls out of this.
