Standard Specification for Pearlitic Malleable Iron

Scope

1.1 This specification covers pearlitic malleable iron castings for general engineering usage at temperatures from normal ambient to approximately 750°F.

1.1.1 For continuous service at temperatures up to 1200°F design factors should be incorporated to compensate for possible property changes, as demonstrated by Marshall and Sommer and by Pearson.

1.2 Without knowledge of casting geometry and process details, no quantitative relationship can be stated between the properties of the iron in the various locations of a casting and those of a test bar cast from the same iron.

1.3 The values stated are in inch-pound units and are to be regarded as the standard. A complete metric companion specification A220M has been developed; therefore, no metric equivalents are shown in this specification.
