PRODUCT PARAMETERS
Overview
NIMONIC alloy 90 (UNS N07090/W. Nr. 2.4632) is a wrought nickel-chromium-cobalt base alloy strengthened by additions of titanium and aluminum. It has been developed as an age-hardenable creep- resisting alloy for service at temperatures up to 920°C (1688°F.） It is widely used and a well proven alloy in high temperature conditions. Some typical applications for Nimonic® 90 include turbine blades, discs, forgings, ring sections, hot-working tools and other extreme environments.
