What is graphitisation? TWI

Graphitisation is a microstructural change which can occur in carbon or low alloy steels that are exposed to elevated temperatures, between approximately 425°C and 600°C, for long periods of time. It is most often encountered in boiler tubes and related equipment that have experienced service temperatures in this range for several thousand hours.
