6、e Year Review and update of this specification.1. SCOPE1.1 FormThis specification covers a free-machining, corrosion-resistant steel in the form of bars, wire, forgings, and forging stock.1.2 ApplicationThese products have been used typically for parts which may be swaged or hot upset during fabrica

7、tion 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.2. APPLICABLE DOCUMENTSThe issue of the following documents in effect on the date of the p
