If I bend a piece of 1" x 1/8" ms flat into an 'L' shape, how do I

Would I heat it to 'red', bend it, then quench it in water/oil? Or
bend it cold, heat it, quench it?

Thanks for all the helpful replies.

I was thinking more of a bracket like this

They pretty much stay in shape under light loads. Are they just bent?

Yup, just mild steel bent in a press usually.

Bent in a press 'always'

about 10 tons will do that adequately.

You can just about do a strip of 1/8" in a vice with a block and a mallet.

You would need to avoid the vice jaw putting in a sharp corner in the
bend that could produce a stress fracture point. Put a piece of round
bar in the vice, as high as possible in the jaw on the side you are
going to bend towards. Diameter = thickness times 2 minimum.
