Boiling water is (effectively) never hotter than 100c, so the inside of the egg never gets hott enough to turn water into steam. When the egg touches the bottom for too long it gets heat conducted straight from the metal of the pot allowing some of the water in the egg to boil and burst the shell.
Why did my egg explodes while boiling?
Eggs have an air chamber at the bottom. Boiling them means the air inside expands and causes an explosion if you did not put in a pin prick to help the air escape the egg.
