ASTM A47/A47M-99(2004)

Standard Specification for Ferritic Malleable Iron Castings

ABSTRACT
This specification covers ferritic malleable castings for general engineering usage. The castings are classified as Grade 32510. The chemical composition of the iron shall be such as to produce the structural and mechanical properties required by this specification. Tension test may be machined from the standard cast bar to the required dimensions. The microstructure of the malleable iron shall consist of temper carbon nodules distributed through ferritic matrix and shall be free of excessive pearlite, massive carbides, and primary graphite. All castings, on visual examination, shall be sound and free of obvious shrinkage and porosity. The castings shall conform to the dimensions given by this specification.
SCOPE
1.1 This specification covers ferritic malleable castings for general engineering usage at temperatures from normal ambient to approximately 400°C (750°F).
1.2 No precise quantitative relationship can be stated between the properties of the iron in various locations of the same casting and those of a test specimen cast from the same iron (see Appendix X1).
1.3 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 with the specification.
