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.
WebType 1. Heat for carbonisation is generated by allowing part of the wood charged to burn to provide the heat to carbonise the remainder. The rate of burning is controlled by the amount of air admitted to the kiln, pit, mound or retort.
