1/8 hard 304 tube mechanical properties 1

[lewbloms]

Anybody know a source acceptable to the FAA for this information? MIL-HBK-5J only addresses annealed, 1/4, 1/2, etc. Some vendor's handbooks have it, but I have to have a better source.

The 'frational hardness' values relate to STRIP only. They are currently found in ASTM A666. You cannot apply these to tubing, they don't fit, and they don't exist in any tube specs.
When we do aircraft (or industrial for that matter) the specification always has specific tensile values in it.
I could give you some examples if you like, but the real task is select a specific AMS specification and use the tensiles listed there.

Corrosion never sleeps, but it can be managed.
