ASTM standards are developed through consensus among producers, specifiers, fabricators, and users of steel mill products. The ASTM designation system for metals consists of a letter (A for ferrous materials) followed by a sequential number, with each designation applying to specific products or testing methodologies. This article presents a comprehensive list of ASTM standards covering ferroalloys, various other materials, and relevant terms and definitions. It serves as a reference for industry professionals seeking guidance on material specifications and standardized terminology.
ASTM International develops widely recognized standards for materials and products used in the steel industry. The ASTM designation system for metals uses a letter to indicate the material family—A for ferrous materials—followed by an arbitrarily assigned sequential number. For example, ASTM A548 refers to cold-heading quality carbon steel wire used for tapping or sheet metal screws.
