As far as I know you can only have an item break if its past +5.
Steady stops the Durability from reducing (past +5) and nothing to do with breaking.
You cannot lose the sos rating but XMoshe is right that if something breaks then throw it away, it is NOT repairable. Having Immortality on an item will stop it from breaking.
If an item breaks, it disappears completely, it doesn't become unrepairable.
