if this doesn't fit the mandate of your groups. I won't repost if I
don't get an answer. Thank you, though, for your time in advance.

I'm trying to find a formula or a chart that'll help me figure out
average/ideal steel strengths given a bar of a certain diameter. For
instance, how thick of a rod of steel would a person need to keep it
from buckling when a super-human applied a ton of pressure. I realize
there are different types of steel, purities, etc., which is why I
thought there might be a kind of slide-rule-esque chart for figuring
X-type for Y-weight is Z-thickness.

Any help would be appreciated. I've Googled and checked Wikipedia, but
the best they seem to have is related tooling equipment and melting
points, respectively, which is interesting but not what I need. Again,
thank you in advance for your help!

Did you really, truly google "steel strength"? I just did and got
1,890,000 hits.

The quality of the steel usually doesn't enter into the solution until

you get into very SHORT columns--the limiting factor is the L/r ratio--
(which is the length / by the slenderness ratio.. long skinny columns
fail by buckling)---Short fat columns fail by deformation at their Yield
Strength--similar to the same size bar in tension.

This is a very simple explanation for a problem that might require quite
a bit of mathematical calculations.

Great now can u sort out some good useful ones as the o/p obviously is a
busy sole and doesn't have time to sift through the results.

Exactly; Google for Euler buckling and once you understand that you may be
able to formulate a better question.
