Further analysis including material composition verificati

38、on, heat treat process parameter review, and/or tensile property measurement on product with “out-of-range hardness” may be necessary. 8.3 Copper temper designations are defined in ASTM B 601. 8.4 Terms used in AMS are clarified in ARP1917. 8.5 Dimensions and properties in inch/pound units are prima
