If all else fails TACK weld a steel bar to the nut and really thwack it!

Then grind the weld off ..... Umm ...assuming you have another angle grinder.

Or you could be an animal .. just hit the disc edge with your hammer .... at a tangent to and in the same plane as your disc.... you should eventually make a nice nick in the edge that your hammer can really impinge on.

Dan ...Ive been in engineering and related trades ... as have many others on here ...for a long time.

As John says you will run the risk of breaking something if you use to much abuse.
Theres an Art to gentle persuassion.
