On a boiler, what is the most dangerous effect of a scale

Scale build up in a boiler water-space is a big "no-no" and will generally result in a failure of the boiler material through two primary mechanisms - The scale will allow under-deposit corrosion to take place which can result in pitting and severe loss of boiler material ultimately leading to a failure i.e. explosive leak of steam and water from the boiler.
