1.1 This specification2 covers austenitic ductile iron, Type D-2M, Classes 1 and 2, for compressors, expanders, pumps, valves, and other pressure-containing parts intended primarily for low-temperature service. 1.2 These grades of austenitic ductile iron are characterized by having their graphite substantially in a spheroidal form and free of flake graphite. They are essentially free of carbides and contain sufficient alloy content to produce a stable austenitic matrix down to −423°F [−252°C] (liquid hydrogen). 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.3.1 Within the text, the SI units are shown in brackets. 1.4 The following precautionary caveat pertains only
to the test methods portion, Section 11, of this specification:
Standard Test Methods for Tension Testing
of Metallic Materials Standard Test Methods for Notched Bar
Impact Testing of Metallic Materials (Includes all amendments and
changes 4/13/2023). Practice for Sampling Steel and Iron for
Determination of Chemical Composition (Withdrawn 1996) Test Methods for Chemical Analysis of
Steel, Cast Iron, Open-Hearth Iron, and Wrought Iron (Withdrawn
