Q: I have an deep space application that may experience varying temperatures from extreme highs as well as cryogenic. I’ve been told about A286, but can it be used at cryogenic temperatures too?
A: Yes, A286 can be used at cryogenic temperatures down to -320 where it will remain ductile and offer excellent strength, as well as non-magnetic properties. In addition A286 bolts are usable to 1300F/700C. Without knowing the specific temperatures of your application I cannot say for sure A286 bolts would be the right fit but this should give you some guidance.
