    Elgiloy®

    UNS R30003

    W.Nr 2.4711

    Applications

    Springs, seals, semiconductor components, orthodontics, medical devices, surgical implants, satellite communications equipment, and weapons systems.

    Description

    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).
