High-temperature applications refer to processes or environments where materials are exposed to elevated temperatures, typically above 200°C (392°F). These applications are common in industries such as metallurgy, aerospace, and power generation, where components must withstand extreme heat without losing their structural integrity or performance. Materials used in high-temperature applications include specialized alloys, ceramics, and composites designed to resist thermal degradation. Examples include superalloys used in jet engines and refractory materials in furnaces. Proper selection of materials is crucial to ensure safety, efficiency, and longevity in these demanding conditions.
