You're right. All mu metal undergoes annealing in a hydrogen atmosphere. The latest mu metal sub's use cobalt instead of nickel and then super cool it to cryo temps immediately so that the cobalt stays amorphous like glass. You find it listed as metglas in catalogs.Cobalt has always been more permeable than nickel. Danger is that it can saturate.
