Elgiloy is a non-magnetic Cobalt-Chromium-Nickel-Molybdenum alloy having a unique combination of very high strength while maintaining excellent formability, excellent corrosion resistance, and high fatigue strength. Additional strength increases of up to 25% can be achieved through aging cold reduced material. Elgiloy is highly resistant to sulfide stress corrosion cracking, and as a result is the alloy of choice in the most demanding sour well environments. In seawater, Elgiloy is virtually immune to crevice and stress corrosion and pitting even at the highest strength levels. Elgiloy performs across a wide range of temperatures: from cryogenic up to 850°F (454°C).
