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.
