Is Monel usable at cryogenic temperatures?
Not only does Monel offer excellent high strength at temps to 1000F, it is also usable in subzero temperatures. Monel 400 has demonstrated good toughness and ductility in US Navy Tear Tests down to -320F. In addition, K500 bolts offer increased strength, with little loss to ductility and toughness down to the temperature of liquid hydrogen.
