Matt,
I was told Cro Mo was heavier by David Crower, he was referring to their crankshafts and rods. He told me the percentage difference, but of course I forgot it. Their steel cranks are lighter than their Crome Molly cranks when machined in identical ways.
I have not tried to verify it, but from the site you quoted by clicking on the metric weight link:
1018 0.2843218 /cu in
4130 0.2835992 /cu in
4340 0.2835992 /cu in
That's a fraction of a percent difference but Crower had told me it was several percent. Now I'm confused...Last edited by David Pozzi; 08-01-2005 at 09:47 PM.

As you know, Chrome Moly is a generic name for high Chromium and high Molybdenum content steel. Crower is using 4340, and from what I could tell, it's the exact same weight as 4130. Even the 5xxx series steels that I randomly looked at weighed the same. Nitriding didn't have any effect on weight.
I'd like to know what Mr. Crower was refering to! I also wonder if I'm getting bogus numbers.-Matt
