High-Temperature Alloys: Applications and Specifications
High-temperature alloys are essential in industries requiring exceptional resistance to heat, corrosion, and mechanical stress. These alloys are commonly used in gas turbines, oil drilling, marine engineering, diesel engines, internal combustion engines, and the chemical industry. Typical applications include turbine disks, turbine blades, condensers, superheater tubes, and machinery components subjected to high temperatures and corrosive environments.
Casting Superalloys
Casting superalloys are crucial for manufacturing high-temperature components such as gas turbine parts, chemical and textile industry guide vanes, nozzles, entire impellers, molds, and other oxidation- and corrosion-resistant machinery parts.
