Alloy 7040, UNS A97040, ASTM B209

AIMS 03-02-019

 

 

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.
