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

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

It certainly bends very easily when red hot. I suspect that the
resulting bend will be stronger if bent when red hot. I usually dunk
it in water afterwards, just to cool it down so I can hold it. I'm not
sure if that affects its strength, probably not.

Probably does.
Probably doesn't have much effect on its resistance to bending.

If it were high carbon steel it would make it hard and brittle.
You then need to temper it by heating it to a straw-blue colour before
letting it cool.
