This is totally untrue. The most common method of making something
"very hard on the outside and left soft on the inside" is by case
hardening which can be done to any iron alloy regardless of how it is
formed.

You must remember that his manufacturing experience may have been
before carbon was discovered.

On the another hand I would love to see the forging press that punched
out the frame for an old LeBlond gear head lathe, say something with a
20 foot bed.
