Differential expansion is well known to most mechanical engineers - it frequently is the cause of leaks or issues.
However nuts and bolts suffering differential expansion so badly to cause a total failure I have never heard of. I would attribute at least half the blame to the original designer for not having enough dimensionality and/or strength margin on the threads.
600psi steam is only at a little over 225 degrees Celsius, which really isn't much thermal expansion for metals.
