    with proper bend radius you can bend N without cracking, as to strength, that's a good question, but lots of bent parts out there from N in factory and homebuilts, Normally your loads are in shear. (I think) but the stress experts can answer better.

    Yes, all the time. Generally with r=1.5t.

    It comprises the strength a heck of a lot less than making parts out of annealed steel.
