Designation: A 395/A 395M – 99 (Reapproved 2004)
Standard Specification for
Ferritic Ductile Iron Pressure-Retaining Castings for Use at
Elevated Temperatures
1
This standard is issued under the fixed designation A 395/A 395M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope
1.1 This specification covers ductile iron castings for
pressure-retaining parts for use at elevated temperatures. Cast-
ings of all grades are suitable for use up to 450°F. For
temperatures above 450°F and up to 650°F, only Grade
60–40–18 castings are suitable (Note 1).
1.2 Valves, flanges, pipe fittings, pumps, and other piping
components are generally manufactured in advance and sup-
plied from stock by the manufacturer, jobber, or dealer.
1.3 For supplemental casting requirements, Specification
A 834 may be utilized.
1.4 The values stated in either inch-pound units or SI units
are to be regarded separately as standard. Within the text, the
SI units are shown in brackets. The values stated in each
system are not exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the
two systems may result in nonconformance to the specification.
NOTE 1—For service other than as specified in this section, reference
should be made to Specification A 536 for Ductile Iron Castings.
