Thanx for the info. I'll admit Peter had it right. I live in nuclear submarine country and I was having this discussion last night with a couple of reactor engineer friends of mine. I hadn't considered that pressure is necessary to raise the temperature of steam and thought it was merely dependent on the amount of energy you put into the system. I was a little bass-ackwards in my thinking since water can drop below 32 degrees once it completely freezes and I figured the opposite would be just as true for steam.
