Precipitation Hardening High Strength Alloys , W. Nr. 2.4632 Nimonic 90 Bar

UNS N07090 Nimonic Alloy High Strength W. Nr. 2.4632 Precipitation Hardenable

Introduction

UNS N07090 is a precipitation-hardenable nickel-chromium-cobalt alloy having high stress-rupture strength and creep resistance at temperatures to about 1700°F (920°C). UNS N07090 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.
