40、t margin is for the convenience of the user in locating areas where technical revisions, not editorial changes, have been made to the previous issue of this document. An (R) symbol to the left of the document title indicates a complete revision of the document, including technical revisions. Change
41、bars and (R) are not used in original publications, nor in documents that contain editorial changes only. 8.2 Hardness on annealed product should be as shown in Table 5 below determined in accordance with ASTM E 18. Hardness has been used to verify that product is properly processed, but an “out of
42、range hardness number“ is not always indicative of product with “out of specification tensile strength”. Further analysis including material composition verification, heat treat process parameter review, and/or tensile property measurement on product with out of range hardness may be necessary. TABL
