So is Chromoly steel better than 1020 steel? I read somewhere that its best to use 1020 but Im not really sure. I wish I could find a source where they compare all of the different steels by weight and strength. That would be amazing lol.

Chromemoly seems to be getting replaced by 1020 in a lot of applications. I think 1020 is a bit more expensive, but its not as difficult to weld.
as far as metallurgy, here is a very basic primer for you:

That second link discusses tensile strength, but under the "see also" there are links for the other physical properties of materials.
