If your bike is made of steel, then you should be ok. But I strongly suggest you take it to a bike shop as they’ll have a derailleur hanger tool that is specifically designed for the job. It’s really very difficult to get it completely straight without that tool.

I’ve bent a lot of steel ones back, only cracked one. Had to chase threads on a couple. Sometimes the hole will ovalize on you if you just use a crescent wrench. A couple of times I’ve found myself without the Park Tool derailleur hanger tweaker and just threaded the axle of a rear wheel into the hole and used that rear wheel to tweak the hanger. Having that axle threaded in helps keep the hole round.

Should bend back easily…..This time. More likely to break if it happens again.

I recommend that you take the wheel off, put the entire tab within the jaws of a bench vise, and then tighten the jaws to flatten the tab. If you don’t have a vise, place the tab concave side down on a flat surface, place a rigid plate on top of the tab (metal, wood, …), and then hammer it flat by hitting the rigid plate. I suggest that you do either of those rather than attempt to bend it back with an adjustable wrench where you risk bending it in other places as you apply force to straighten the existing bend.
