This specification covers UNS N08120, UNS N08800, UNS N08810, and UNS N08811 in the form of hot-worked and cold-worked rod and bar. Alloy UNS N08800 is normally employed in service temperatures up to and including 1100?F (593?C). Alloys UNS N08120, UNS N08810, and UNS N08811 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. The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
