Standard Specification for Vacuum-Treated Steel Forgings for Generator Rotors
|Publication Date:||1 March 2006|
|ICS Code (Iron and steel forgings):||77.140.85|
This specification covers vacuum-treated basic electric steel forgings for generator rotors.
Supplementary requirements are provided, both in this standard and in Specification A 788/A 788M, for use when additional testing, inspection or processing is required by the purchaser.
The values stated in either inch-pound or SI (metric) units are to be regarded separately as standards. Within the text and tables, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other. Combining values from the two systems may result in nonconformance with the specification.
Unless the order specifies the applicable "M" specification designation, the material shall be furnished to the inchpound units.
A Summary of Changes section appears at the end of this standard.
