It is the use to which the material is put that determines its suitability. Based on the question as stated, no reliance can be placed on any answer in this forum!

  • For example, were the material to be turned into a pressure vessel, then the Engineer/Surveyor for the company that supplies burst/collapse indemnity insurance cover for the vessel should be the first point of contact for an enquiry like this, and certainly not any random bunch of strangers one might just happen to come across on the internet - the latter is not liable for the vessel when it goes BANG!
  • The properties of materials at various temperatures can be found by using an internet search engine. Is Google not available in that part of the world?

If SS416 is brittle and shatters at -65dC, then tissue paper is stronger. Why would anyone be surprised?

For one source regarding the low temperature abilities of SAE 51416, see the below reference.

I suggest you discuss this matter with a materials engineer who is familiar with properties of 400 series stainless steel at cryogenic temperature. Be prepared to discuss the history of your parts, the manufacturing methods, and the heat treating history. Also, be aware that gun barrels are made from this material. I doubt that anyone wants their barrels to fail at low temperature.

Water ice and most types of stone would also be pretty good.
