ASTM specifications represent a consensus among producers, specifiers, fabricators, and users of steel mill products. ASTM’s designation system for metals consists of a letter (A for ferrous materials) followed by an arbitrary sequentially assigned number. These designations often apply to specific products, for example A548 is applicable to cold-heading quality carbon steel wire for tapping or sheet metal screws.
This article contains a list of standards that covers among other things:
