Alloy 7040, UNS A97040, ASTM B209
AIMS 03-02-023
TEMPER TYPES
7040 is supplied in mostly below of tempers:
- T7451 - Solution heat-treated, stress-relieved by controlled stretching and then artificially overaged (between T73 and T76). The products receive no further straightening after stretching.
- T7651 - Solution heat-treated, stress-relieved by controlled stretching and then artificially overaged in order to achieve a good exfoliation corrosion resistance. The products recieve no further straightening after stretching.
SUPPLIED FORMS
7040 is supplied in plate.
