Product Description

R30003 Shock and Corrosion resistant Superelastic Alloy High Hardness

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.
