11 HIGH TEMPERATURE EXPANSION JOINTS Expansion Bellows designed for 900°C (1652°F). In this project temperature and flexibility were the main items of concern. Particularly challenging was the selection of material with sufficient resistance, strength and flexibility needed to ensure smooth and safe operation. The material selected were Alloy 188. This material belongs to the alloy family chosen for equipment used in super demanding applications in e.g., space exploration missions, such as equipment landing on Mars. This Alloy material family can withstand the high temperatures when entering the Martian atmosphere. Shipping industry Europe 2021-4721-01014
