PRODUCT DETAILS

Elgiloy®

UNS R30003 
W.Nr 2.4711

Elgiloy® is a non-magnetic Cobalt-Chromium-Nickel-Molybdenum alloy having a unique combination of very high strength,excellent corrosion resistance and high fatigue strength. 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 and can operate at cryogenic temperatures up to 850°C (454°C). Applications include springs, torsion bars, seals, medical devices & implants and orthodontic wire
