Abstract
The elevated-temperature fracture toughness of Incology 800H material for in-service furnace tubes was studied at 550° and 680°C. The elevated-temperature fracture toughness of Incology 800H material for in-service furnace tubes decreased with increasing temperature. The fracture toughness was 80-100 kJ/sq m at 680°C and higher at 550°C. The test results provided an important basis for the safety assessment of short-term elevated-temperature fracture of in-service furnace tubes.
