Elgiloy alloy(Co40CrNiMo) , AMS 5833, UNS R30003
Chinese 3J21, YB/T 5253-93

Note:
This Cobalt-Chromium-Nickel alloy also known as Elgiloy? Gives a combination of high strength, ductility and good mechanical properties and is age hardenable. Phynox also has excellent fatigue life, corrosion resistance in numerous environments and is non-magnetic. This alloy is recommended where a high resistance to corrosion and / or low relaxation at temperatures up to 380C are required.
