Cobalt Alloy, Corrosion and Heat-Resistant, Strip 20cr 15ni 40co 7.0mo 16fe Vacuum Induction Plus Consumable Electrode Melted Solution Heat Treated and Cold Rolled AMS5876C

This specification covers a high-strength, corrosion and heat resistant cobalt alloy in the form of strip 0.100 inch (2.54 mm) and under in specified thickness and 4.000 inches (101.60 mm) and under in specified width.

This strip has been used typically for springs requiring a combination of high strength up to 800 degrees F (427 degrees C) after aging, excellent corrosion resistance, and good fatigue properties, but usage is not limited to such applications. The alloy is nonmagnetic.
