Magnetite (Fe 2 O 4) is formed in a boiler circuit under anaerobic conditions and is very stable, dense and uniform at high temperatures (greater than 400 F). Between 250 F and 400 F, magnetite forms less rapidly and is porous and irregular. Below 250 F, magnetite forms very slowly. Webhematite layers up to 15µm thickness inside the tubes do not act as insulation. They clearly show the process of long term overheating on the outside of boiler tubes which in turn leads to the initiation of flaws.
