ASTM A279 is a standard specification for high-speed tool steel, which is a type of steel alloy used for making high-speed cutting tools, such as drill bits, saw blades, and milling cutters. This specification covers the requirements for high-speed tool steel in the form of bars, billets, and forgings. In this article, we will provide an overview of the ASTM A279 standard, its chemical composition, mechanical properties, and applications. Astm A279 Pdf
