This specification covers three types of a free-machining, corrosion-resistant steel in the form of bars, wire, forgings, and forging stock.
These products have been used typically for parts on which the amount of machining warrants use of a free-machining grade of steel requiring corrosion resistance similar to the 18-8 type of steels but not subjected to temperatures exceeding 700 degrees F (371 degrees C) during fabrication or in service, but usage is not limited to such applications.
