Elgiloy
Elgiloy is a unique combination with extremely high strength, adhering to excellent formability, excellent corrosion resistance, and high fatigue strength in a non-magnetic cobalt chromium nickel molybdenum alloy. By aging cold rolling data, up to 25% of the rated strength can be added. Elgiloy is resistant to chemical stress corrosion and has high resistance to cracking, and as a result, it is selected for alloys in the most severe acids and environments. In seawater, Elgiloy alloy ® It is almost free from crevice corrosion and stress corrosion, and at a high strength level, even corrosion. Elgiloy operates over a wide temperature range: from low temperature to 850 ° F (at 454 ° C).
