Nimonic 90 UNS N07090 Age Hardening Creep Resistance High Strength Ni-Cr-Co Alloy

Nimonic 90 Precipitation Hardenable Ni-Cr-Co Alloy with High Strength

Introduction

Nimonic 90 is a precipitation-hardenable nickel-chromium-cobalt alloy having high stress-rupture strength and creep resistance at temperatures to about 1700°F (920°C). Nimonic 90 also has good resistance to high-temperature corrosion and oxidation. Nimonic 90 is used for blades and discs in gas turbines, hot-working tools, and springs.

Characters

• High stress rupture strength and high creep resistance at high temperatures
• Good resistance to high-temperature corrosion and oxidation
• Age-hardenable
• High temperature dynamic applications

Application

The alloy is used for turbine blades, discs, forgings, ring sections and hot-working tools. Also used to make Aerospace fasteners.
