Nickel Alloy K465 / ZhS6U
General Technical Characteristics
K465 (ZhS6U) is a heat-resistant cast nickel-based superalloy designed for components operating under high temperatures and mechanical loads. It features a polycrystalline equiaxed cast structure and is strengthened by the γ′ (gamma prime) phase, which provides high-temperature strength and resistance to creep deformation.
The alloy is primarily used in gas turbine components, including rotor and stator blades, guide vanes, and other parts of the hot section of aircraft and industrial gas turbine engines.
