Abstract

Form This specification covers two types of free-machining, corrosion- and heat-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 the use of a free-machining grade of steel requiring corrosion resistance similar to the 18-8 type of steel and that will be subjected to high temperatures during fabrication or in service, but usage is not limited to such applications. This steel is not intended for parts to be brazed at temperatures higher than 1350 °F (732 °C) or to be fusion welded. Classification The steels covered by this specification are classified as follows: Type 1 - 18Cr - 10.5Ni - 0.26S - 0.60Cb Type 2 - 18Cr - 10.5Ni - 0.14P - 0.25Se - 0.60Cb Unless a specific type is specified, either type may be supplied.
