SAE INTERNATIONAL AMS4154R Page 6 of 6 8.2 Hardness should be not lower than 135HB/10/500 or 140HB/10/1000, determined in accordance with ASTM E 10. Hardness has been used to verify that e

41、xtrusions have been properly processed, but an out-of-range hardness number is not always indicative of extrusions with out-of-specification tensile properties. Further analysis, including material composition verification, heat treat process parameter review, and/or tensile property measurement on

42、extrusions with 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 units are primary; dimensions and properties in SI units are shown as the approximate equivalents of the primary units and are presented only for infor

43、mation. 8.5 Purchase documents should specify not less than the following: AMS4154R Form and size or section identification of extrusions desired Quantity of extrusions desired Property and acceptance requirements from the cognizant engineering organization applicable to sizes outside the range listed in 1.1.1.
