It will be a sample of a material I'm developing for use in high
pressure hot oxygen for rocket engines.
(I finally got the explosives licensing sorted today! Yippee! :) I have
to say that both the Wiltshire Police especially, and also the HSE, were
very helpful, no "jobsworth"-ing, which was extra-good as neither had
come across the situation before)
I haven't made the sample yet, what size and shape would be good?
Expected yield strength will be around 300 MPa / 40 ksi, but this is no
more than a guess. It's a near-net-shape technology , and a pig to
machine, so I'll have to make a sample especially. As small as
practicable please, as it's kinda expensive (ouch).
Posting is no problem. It will take a week or so to make a sample once I
know the size and shape needed.
 I will give details eventually, but not now, it's still in
development. Not very useful unless you want to work in hot HP oxygen
