Special AlloysSheet/Plate
Description (English)
NIMONIC Alloy 90 is supplied in the heat-treated condition of 1975°F air cool plus 1300°F, producing yield strength of 800 MPa, tensile strength of 1234 MPa, elongation of 33%, and hardness of HRB 38. The alloy is manufactured to AMS 5829 standard. The combination of cobalt solid-solution strengthening and Al + Ti precipitation hardening delivers superior mechanical properties at elevated temperatures. NIMONIC 90 is widely specified for the most demanding hot-section components in aerospace gas turbines, rocket engines, and critical high-temperature structural applications where maximum strength-to-weight ratio and thermal stability are required.
