Some cheap bars will just increase the diameter to make it more "sturdy" or to increase the wt capacity. Then there are high quality bars where they can keep the bar thin (think less than 30mm), and they usually use a PSI rating instead of a wt capacity.
You're probably gonna want to google for the details. I'm sure I'm pissing someone off by generalizing such a specific topic lol

My question is what makes some bars have a higher weight capacity? They all seem to be made of chrome-plated steel and they all weigh the same. Are the bearings maybe the limiting factor? Any reason not to try to load more than 310 lbs on this?

I think I was trying to get a stake out of the ground or something, and figured a barbell would be fine - but it bent right towards the middle.
I was able to bend it back by removing the collars and running it over with my truck (with a few weights under one side), and now the bend isnt even noticeable. Since bending it Ive squatted ~400 lbs and it is still fine. I was worried it was gonna bend right back after.
Not sure if mine is the same as the one linked here, but im guessing they are pretty similar.
For $30 I'll buy another crappy bar and spray paint it for outdoor use. If you are doing Olympic lifts or can do a LOT of weight this bar probably isnt for you. Im guessing 90%+ would be fine with this bar.
If you want to spend $$$ Rogue boneyard barbells (scratch and dent) are selling for like ~200 - so its a LOT more money for a bar that the average person wont be able to tell the difference. https://www.roguefitnes
That doesn't mean any oly bar is going to snap, just saying that for the same diameter piece of metal, the ability to handle more weight without damage is going to come from using an alloy that can be hardened and isn't delivered dead soft.

Small nitpick: plastic deformation occurs when the stress exceeds the material's yield strength. The Young's Modulus is a material property and merely describes how much the material will deform under specific stress within the elastic deformation range on stress-strain curve.

Yield stress is typically used to define the point at which permanent deflection can occur.
Ultimate stress is when static load creates fracture.
Steel can be alloyed, work hardened, heat treated, etc to increase strength all while leaving size the same.
This isn't a perfect explanation but it's a little less misleading..
