ASTM Standard List: Stainless Steels

7 min read • Updated July 2026 • Normas e classificação › Normas globais de materiais

Abstract

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.

Overview of ASTM Standards for Stainless Steels

ASTM specifications reflect a consensus among producers, specifiers, fabricators, and users of steel mill products. The ASTM designation system for metals uses a letter (A for ferrous materials) followed by an arbitrary sequential number. For instance, A548 applies to cold-heading quality carbon steel wire for tapping or sheet metal screws.
