That would work in much of the world on paper. Not that the world sees the upper range as ambient. The metal may well approach the upper range during a sustained heat exposure.
Wonder what the safety factor actually is?
There are three basic types of temperature exposures:
One, a journey. Got super hot, or cold for a while, then returned to moderate, or acceptable range.
Two, excursions. Got extreme and stayed there for a non trivial time. (Scaled to the properties of whatever it is)
Three, wild ride! Journeys all over the place.
In addition, these can be one off events, or cyclic.
Windows get a kind of cyclic ride in many places. A bond holding "for a while" always has the question of what "while" really means.
Microfractures due to highly localized stress and strain, pre loaded in as an artifact of welding, would be my primary concern.
