MECHANICAL PROPERTIES Table I lists minimum yield strength, minimum ultimate tensile strength, and minimum elongation values. Yield strength, ultimate tensile strength, and elongation property values are determined with standard test method ASTM B557. This table also includes hardness screening criteria values, indicated in parentheses. As applicable, minimum electrical conductivity values are also specified. TABLE I
