according to www.matweb.com
mild steel
0.284 lb/in³
chromoly
0.284 lb/in³
Moly cages are lighter because your allowed by NHRA to use a thinner wall.

Physical properties can differ greatly though depending on manufacturing and heat treatment i.e. tensile strength, yield, toughness etc.

The place I use to work at is a dealer for Performance Automotive K-Members, the Spohn one looks like it is constructed very similar with more gussets.
The PA moly one was a lot lighter, you're talking .083 vs .120 wall tubing. My moly K-member is 17 LBS. I don't know the exact weight of the mild steel K-member but if felt twice as heavy as the moly one. The stock one was 42 LBS. The moly one is well worth the price increase IMO. It says right on Spohn's site that the moly has .083 tubing and the mild steel is .120.
I dropped 105 LBS when I changed everything, PA K, PA A-Arms, PA Rack, Spohn coil over conversion with shock towers. (this was a 3rd gen)
IMO, all of Spohn's stuff is better quality than what I've seen from PA. If I was buying one right now I'd definitely buy the Spohn.
