High Temperature Strip
Product Details
Nimonic 90 high temperature alloy strip is a high-performance nickel-chromium-cobalt superalloy specifically engineered for the most demanding aerospace applications. As one of the premier creep-resistant alloys, it is renowned for its exceptional high-temperature strength, oxidation resistance, and thermal fatigue properties. These characteristics make it the ideal material for turbine blades and other critical hot-section components in jet engines and gas turbines.
This advanced superalloy strip combines outstanding mechanical properties with long-term structural stability at temperatures up to 920°C (1688°F), outperforming many conventional nickel-based alloys under extreme operating conditions. Whether used in military, commercial, or industrial gas turbines, Nimonic 90 delivers reliable and consistent performance in environments subjected to high temperatures and stress.
Nimonic 90 offers a highly desirable combination of properties that make it the material of choice for turbine blades and other critical aerospace components:
Superior Creep Resistance: Maintains strength under continuous stress at high temperatures, making it ideal for high-pressure turbine stages.
Excellent Oxidation Resistance: Forms a stable protective Cr₂O₃ oxide layer at elevated temperatures, preventing corrosion and material degradation.
High Tensile Strength: Capable of sustaining tensile strength up to 1000 MPa (145 ksi) at room temperature, which ensures durability and performance over time.
Outstanding Thermal Fatigue Resistance: Withstands repeated thermal cycling, maintaining integrity even during rapid heating and cooling cycles.
Age-Hardenable: Strengthened through gamma prime (γ') precipitation hardening, enhancing its mechanical properties and durability.
Good Fabricability: The alloy strip can be forged, machined, and welded with proper techniques, making it suitable for complex turbine components.
