ASTM A597/A597M-14 PDF

1.1 This specification covers tool steel castings having chemical compositions similar to those of the standard wrought grades.

1.2 Several grades are covered and are designated by chemical composition shown in Table 1.

1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. Inch-pound units are applicable to material ordered to Specification A597 and SI units for material ordered to A597M.
