ASTM A395/A395M-99e1 PDF

1.1 This specification covers ductile iron castings for pressure-retaining parts for use at elevated temperatures. Castings of all grades are suitable for use up to 450F. For temperatures above 450F and up to 650F, only Grade 60-40-18 castings are suitable (Note 0).

1.2 Valves, flanges, pipe fittings, pumps, and other piping components are generally manufactured in advance and supplied 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.
