1.1 This specification covers ductile iron castings that are subsequently heat treated by an austempering process as defined in .<\/p>\n
1.2 The application of the austempering heat treatment extends the range of properties achievable in ductile iron castings.<\/p>\n
1.3 No precise quantitative relationship can be stated between the properties of the iron in various locations of the same casting or between the properties of castings and those of a test specimen cast from the same iron (see ). However, austempering heat treatment will tend to diminish any differences in mechanical properties.<\/p>\n
1.4 The production of castings, machining (if required), and the austempering heat treatments may be performed by different manufacturers, as covered in Section . The purchaser should establish by contract agreement, at the time of ordering, the responsibility of the various parties for meeting the specification requirements.<\/p>\n
1.5 The values stated in either inch-pound 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.<\/p>\n
