Graphitization of charcoal
WebGraphitization is a microstructural change that occurs in carbon or low-alloy steels exposed to temperatures of about 425–550°C for several thousand hours. Applications involving prolonged exposure at this temperature range, such as economizer tubing, high-pressure steam pipes, and other components, are prone to this form of embrittlement.
