when chromoly reaches its max weight it snaps.

and both can take the same weight that is why the hi-tensile steel frame is thicker.
and gas pipes are made of copper !
There's no such thing in science called, "maximum weight" with respect to chromoly steel, or "hi-tensile" steel for that matter. The weight of the object made of steel (regardless as to the type), is just simply the mass (m) multiplied by the acceleration of gravity (g). W=mg
* Some gas pipes are made of Cu and some are made of something very close to cast iron, but loosely referred to as..."steel". Most households have "steel" pipes.
What do you mean, "they both can take the same weight"?
Are you referring to a force applied to the different steels?...If so, then you're wrong.
The hi-tensile steel needs to be made thicker, if it's going to approach the strength of chromoly steel.
