Does flange bolt expansion processing affect its strength?

Does diameter expansion of the bolt holes on the flange surface affect its strength?
Within a certain range, it shouldn’t be a problem; it’s feasible
It does have an impact; the internal structural stress in your Flangeqiang has changed
It depends on the extent of the diameter expansion and the application requirements, but in principle it is not allowed, as it will definitely reduce the strength of the flange
