882

UNS #T20811

882 is a 5% chromium high temperature alloy possessing extremely high strength at temperatures up to about 1000°F (538°C). The steel is used in critical structural components which require strength in excess of 260 ksi (1793 MPa) at ambient temperatures, or high creep and rupture strength in the 800/1200°F (427/649°C) temperature range. Is is also used in a wide variety of hot working tools.
