'...can you temporary disrupt the property's of MU-steal?...'
.
If you are referring to the ferromagnetic properties then the answer is yes, those properties can be temporarily disrupted by heating above the curie point ~ 870F
.
.
'...how does MU-steal behave during high velocity stress. ie as a spinning disk?...'
.
If I am understanding your question correctly... an object made of Mu metal will behave similarly to a like object made of 300 series stainless when subjected to the same physical stresses.

BTW, I'm not sure that Mu metal really qualifies as a steel, since it is only about 15% iron. I'd call it a nickel alloy.

just a clarification I don't want to heat it. my question is more along the line, can you pas a current through it and disrupt its magnetic shielding property's. like a switch.
I was going to cut slots in it. heating it to 870F might be a viable option, do you know if i can heat parts of it and destroy the ferromagnetic properties in those spots altogether.
If you pass a current through it and the resulting heat is not sufficient to increase the temperature above the curie temp, then it shouldn't change from ferromagnetic to paramagnetic. A new current would lead to magnetic flux in accordance with the right hand rule convention.
.
I don't know what would happen to the ferromagnetic properties if you applied high voltage very high frequency AC to Mu-metal thin enough for skin effect not to be a major concern.....I'd be interested if you dig anything up on this.
.
The change due to heating is reversible (therefore not 'altogether', in the sense I believe you to be asking) passing through the curie temp.... ferromagnetic to paramagnetic on the way up, reversing back to ferromagnetic on the way back down.
