High-Temperature Alloys

High-Temperature Alloys 

High-temperature alloys are materials engineered to withstand elevated temperatures while maintaining their mechanical properties, resistance to oxidation and corrosion, and structural integrity. These alloys are used in extreme environments where materials are subjected to thermal stresses, such as gas turbines, jet engines, and industrial furnaces.
The primary categories of high-temperature alloys include superalloys, heat-resistant steels, and refractory metals. These materials are specifically designed for applications in industries like aerospace, power generation, automotive, chemical processing, and more.
