Hardness has been used to verity that product is properly processed
35、, but an “out-of-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 b
