ASTM Standard List: Stainless Steels

---

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.
