5 REFERENCES
The official reference for UNS numbers is Metals &Al-
loys in the Unified Numbering System, ASTM DS-56. This
document is periodically updated as various material spe-
cificationsare revised,added, or deleted by their sponsor-
ing organizations. Only UNS numbers published in this
reference appear in Section 11, Part A and Part B specifica-
tions, and in the various Section 11, Part D stress tables,
mechanical property tables, and physical property tables.
Nominal compositions are defined by various groups
within the ASME Code committee structure and there
are no published guidelines describing how these desig-
nations are developed.These designations have the great-
est relevance in the arrangement of ferrous materials and,
as indicated previously, the simplest way to obtain these
designations is to look in Section IX of the ASME Boiler
and Pressure Vessel Code and use Table QW/QB-422,
which is arranged by increasing specification number.
These start with the "SA"specificationnumbers, followed
by the "SB" numbers.
