Change bars and (R) are not used in original publications, nor in documents that contain editorial chang

35、es only. 8.2 Hardness of extrusions should be not lower than 80HB/10/500 or 85HB/10/1000, determined in accordance with ASTM E 10. Hardness has been used to verify that extrusions are properly processed, but an out-of-range hardness number is not always indicative of extrusions with out-of-specifica

36、tion tensile properties. Further analysis, including material composition verification, heat treat process parameter review, and/or tensile property measurement on out-of-range hardness, may be necessary. 8.3 Terms used in AMS are clarified in ARP1917. 8.4 Dimensions and properties in inch/pound uni

37、ts and the Fahrenheit temperatures are primary; dimensions and properties in SI units and the Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information. 8.5 Purchase documents should specify not less than the following: AMS4173F Form an

38、d size or section identification number of extrusions desired Quantity of extrusions desired. Whether Type II tubing is required (Where no type is specified, Type I shall be supplied) Whether Temper T6510 extrusions are required Whether Class 1 or Class 2 solution heat treatment is required.
