Users should note that this specificationcontemplates mechanical property gradients.1.3 The values stated in inch-pound units or SI units are tobe regarded separately as standard. Within the text, the SI unitsare shown in brackets. The values stated in each syste

5、m are notexact equivalents; therefore, each system must be used inde-pendently of the other. Combining values from the two systemsmay result in non-conformities with the specification. Inch-pound units are applicable for material ordered to this Speci-fication and SI units for material ordered to th
