Waspaloy® is a high-strength, nickel-based superalloy known for its excellent high-temperature mechanical properties and corrosion resistance.
It is widely used in demanding applications that require strength retention and performance at elevated temperatures, such as gas turbine engines, aerospace components, and high-temperature
structural applications.
Waspaloy® exhibits impressive mechanical properties, capable of achieving a tensile strength of 1103 MPa (160,000 psi) and a yield strength of 724 MPa (105,000 psi) in the age-hardened condition.
Heat treatment of Waspaloy® typically involves solution annealing at a minimum of 1038°C (1900°F). This treatment optimizes the alloy’s mechanical properties and helps eliminate any residual stresses.
Waspaloy® offers excellent resistance to high-temperature oxidation and corrosion. It can withstand aggressive environments, including sulfuric acid, nitric acid, hydrochloric acid, saltwater, and oxidizing/reducing conditions. This corrosion resistance makes it suitable for applications exposed to various corrosive
atmospheres.
