Form
This specification covers three types of a free-machining, corrosion-resistant steel in the form of bars, wire, forgings, and forging stock.
Application
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 steels but not subjected to temperatures exceeding 700 °F (371 °C) during fabrication or in service, but usage is not limited to such applications.
Classification
The steels covered by this specification are classified as follows:
Type 1: 18Cr - 9.0Ni - 0.28S
Type 2: 18Cr - 9.0Ni - 0.14P - 0.28Se
Type 3: 18Cr - 8.5Ni - 3.5Mn - 0.28S
Unless a specific type is ordered, any type may be supplied.
