A number of framebuilders will not replace a steerer tube. The heat required to get the relatively massive steerer tube and fork crown up to working temperature three times (once to install the original steerer, once to remove the original steerer, and once to install the new steerer) has been known to weaken the area resulting in rather dramatic failure.
