6、ises Properties (3.5.2) and Reports (4.4).1. SCOPE1.1 FormThis 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. (See 8.5.)1.2 ApplicationThis wire has been used typically for sp
7、rings and torsion bars requiring a combination of high strength up to 800 F (427 C), excellent corrosion resistance, and good fatigue properties, but usage is not limited to such applications. The alloy is nonmagnetic.2. APPLICABLE DOCUMENTSThe issue of the following documents in effect on the date
8、of the purchase order forms a part of this specification to the extent supplied herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified.
