SAE AMS 5625D-1990 (SAE AMS5625D-1990)

Steel Bars, High Expansion, 9.5Ni 5.5Mn (0.55-0.65C) Cold Finished ( Reaffirmed: Apr 1994 Nov 2004 Apr 2008 )

This specification has been declared ?NONCURRENT? by the Aerospace Materials Division, SAE, as of March 2000. It is recommended, therefore, that this specification not be specified for new designs. ?NONCURRENT? refers to those materials which have previously been widely used and which may be required on some existing designs in the future. The Aerospace Materials Division, however, does not recommend these as standard materials for future use in new designs. This specification covers a high-expansion steel in the form of bars 1.063 inch (27 mm) and under in nominal diameter or distance between parallel sides. Primarily for bolts and screws requiring a coefficient of thermal expansion approaching that of aluminum alloys. This steel is hardenable only by cold working.
