American Society for Testing and Materials (ASTM). Current edition approved Dec. 1, 2006. Published January 2007. Originally approved in 1957. Last previous edition approved in 2001 as B 409 – 01. 5 p. This specification covers UNS N08120, UNS N08890, UNS N08800, UNS N08810, and UNS N08811* 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
