Cobalt Alloy, Corrosion and Heat-Resistant, Round Wire 20Cr - 15Ni - 40Co - 7.0Mo - 16Fe Vacuum Induction Plus Consumable Electrode Melted Solution Heat Treated, Cold Drawn, and Aged
- Aerospace Material Specification
This specification covers a corrosion and heat resistant cobalt alloy in the form of round wire 0.140 inch (3.56 mm) and under in nominal diameter supplied in straight lengths.
This wire has been used typically for springs and torsion bars requiring a combination of high strength up to 800 degrees F (427 degrees C), excellent corrosion resistance, and good fatigue properties, but usage is not limited to such applications. The alloy is nonmagnetic.
Data Sets - Support Documents
The committee of Corrosion and Heat Resistant Steels and Alloys and Specialty Steels and Alloys, AMS Committee F, will prepare, coordinate, and revise documents related to corrosion and heat resistant steels and alloys and specialty steels and alloys technology, such as stainless steels and nickel and base alloys, through the participation of metals suppliers, users, and interested government agencies. Committee activities shall provide a forum for the cooperative interchange of ideas and experience of the participants, resulting in the publication of specifications that embody sound, established aerospace industry practices and requirements to serve the suppliers and customers of aerospace materials.
