Let's take standard chromoly and Reynolds 953 as comparison.
Chromoly UTS is 900 MPa
953 UTS is over 2000MPa
You can get a wall thickness that's half that of chromoly with 953 and it's still as durable as the twice as thick walled chromoly tube.
You translate that tensile strength to material strength and you can then calculate how said piece can deal with in terms of kilograms of force.
Are you suggesting thinner 853 (or whatever other high end) tubing is as durable to impact as thicker 4130 double butted tubing?
If so, i could link article after article showing that isnt thebcase. Thinner higher quality tubing has anhigher tensile strength which allows it to be thinner and therefore lighter, but it isnt as durable in that yes it more easily dents if thw same impact on the same part of the frame were done to it and the basic 4130 chomoly.
