Project BackgroundA leading energy and mining group in South Africa, specializing in coal-fired power generation and high-temperature metallurgical processing, faced critical challenges in ensuring the long-term reliability of key components operating under extreme thermal-mechanical conditions. Components such as boiler tubes, steam pipelines, turbine blades, and high-temperature furnace parts constructed from P91, P92, and 12% Cr heat-resistant steels were exposed to sustained high temperatures (550
