Product Description

R30003 AMS 5876 D Corrosion and Heat-Resistant Cobalt Alloy Cold Rolled Strip



R30003 is a "super-alloy" consisting of 39-41% Cobalt, 19-21% Chromium, 14-16% Nickel, 11.3-20.5% Iron, 6-8% Molybdenum, and 1.5-2.5% Manganese. In China it is called Co40CrNiMo, 3J21-3Jxx is a series of elastic alloys.
It is used to make springs that are corrosion resistant and exhibit high strength, ductility, and good fatigue life. These same properties led to it being used for control cables in the Lockheed SR-71 Blackbird airplane.
UNS R30003 meets specifications AMS 5876, AMS 5833.
Due to its chemical composition, R30003 is highly resistant to sulfide stress corrosion cracking and pitting, and can operate at temperatures up to 454°C.


A-ONE ALLOY is proud to be able to supply R30003 products that meet the requirement of AMS 5876 D and AMS 5833 and ISO 5832-7.
