Monel for Cryogenic Applications

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.

Monel 400 Bolts in Seawater / Stress Corrosion Cracking

Q: I have some machinery exposed to salt water as well has drastic temperature swings. I’m concerned about corrosion but also a material that will become brittle.

A: Monel 400 bolts are an excellent material for salt water corrosion protection and is a go-to material for many marine applications. As far as temperature swings, Monel 400 can be utilized from subzero temperatures up to 1000F. In these kind of marine environments, Monel 400 fasteners would be very resistant to stress corrosion cracking and unlikely crack.
