well for starters i dont know for sure. but:
yes generally stell weakens as it gets hotter, and becomes softer.
when its cooler it becomes stronger, but more brittle
also something can be quite strong and yet very brittle, i know it sounds strange but glass for example is actually quite strong, but as most ppl know, quite brittle.
also a quick google threw up
Consdiering they use different materials in different temperatures for that very reason, they differ quite a bit.Right so there should be an average point of temperature that a certain material is most structurally sound right? Where its less likely to break when induced to kinetic energy. How much could different steels differ?
Like, steel at 240 degrees is weaker than at room temp, cause the heat energy weakens the bonds in the metal, or like when you hit it with liquid nitrogen and hit it, it will shatter, cause the bonds become weaker at those temps than at room temp.

Qaiphyx, you're overly simplifying the question of maximum strength. There's no one number that reaches a maximum, then decreases. The tensile strength decreases with increasing temperature, while the fracture toughness increases with increasing temperature. The optimum temperature will vary depending on load, load rate, geometry, even surface finish.
The bonds are not weaker at low temperature. Rather, the bonds are stronger and less ductile, and it becomes favorable for a crack to propagate right through the material instead of terminating in a plastically deformed area.
Certainly a huge amount! Take a look at any metallurgy textbook, I think you'll find it very useful in clearing up your questions.
