An (R) symbol to the left of the document title indicates a complete revision of the document, including technical revisions. Change bars and (R) are not used in original publicati
35、ons, nor in documents that contain editorial changes only. 8.2 Terms used in AMS are clarified in ARP1917. 8.3 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary; dimensions and properties in SI units and the Celsius temperatures are shown as the approximate eq
36、uivalents of the primary units and are presented only for information. 8.4 Purchase documents should specify not less than the following: AMS5046E Type number of composition desired Product form and size of product desired Quantity of product desired 8.5 Grain size The average grain size resulting f
37、rom using the appropriate test procedures per ASTM E112 will satisfy an ASTM No. 5 or finer grain size when the element defined in 3.3.2.2 as grain refiner is present. Other technical societies have adopted the verification of fine grain steel based on chemistry alone. Included are ASTM International (Documents A6, A20, and A29); American Society of Mechanical Engineers (Documents SA6, SA20, and SA29); American Bureau of Shipping; CSA Group (Canada); EuroNorm documents; American Association of State Highway and Transportation Officials.
