1.1 ,This specification2 covers UNS N08120, UNS N08890, UNS N08800, UNS N08810, and UNS N088113 in the form of rolled plate, sheet, and strip. Alloy UNS N08800 is normally employed in service temperatures up to and including 1100°,F (593°,C). Alloys UNS N08120, UNS N08810, UNS N08811, and UNS N08890 are normally employed in service temperatures above 1100°,F (593°,C) where resistance to creep and rupture is required, and they are annealed to develop controlled grain size for optimum properties in this temperature range.
