1.1 This specification covers ferritic malleable castings for general engineering usage at temperatures from normal ambient to approximately 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.).Note-A complete metric companion to Specification A47 has been developed-A47M; therefore, no metric equivalents are presented in this specification.
