Standard Specification for Austenitic Ductile Iron Castings for Pressure-Containing Parts Suitable for Low-Temperature Service [Metric] (Withdrawn 2001)
01-01-2001
12-31-2010
1.1 This specification covers austenitic ductile iron, Type D2M, 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 -252oC (liquid hydrogen).
1.3 This specification covers only SI units and is not to be used or confused with inch-pound units.
Note 1--This specification is the metric counterpart of Specification A571.The following precautionary caveat pertains only to the test method portion, Section 11, of this specification:This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
