SAE AMS5641G

This specification covers a free-machining, corrosion-resistant steel in the form of bars, wire, forgings, and forging stock. These products have been used typically for parts which may be swaged or hot upset during fabrication and on which the amount of machining warrants use of a free-machining grade of steel, but usage is not limited to such applications. Corrosion resistance is similar to that of the standard 18-8 type steel.
