ASTM Standard List - Structural and Constructional Steels Standards: Part One

---

Introduction to ASTM Standards

ASTM specifications represent an industry consensus among producers, specifiers, fabricators, and users of steel mill products. The designation system employs a letter-number combination, where 'A' denotes ferrous materials, followed by sequentially assigned numbers. For example, A548 specifically applies to cold-heading quality carbon steel wire for tapping or sheet metal screws.

Standard Classification System

The following comprehensive table presents structural and constructional steel standards, organized by standard number. Each entry includes the latest version date, full description, and current status.

Key Categories of Standards

Railway and Transportation Standards

These standards encompass specifications for rails, joint bars, and related components essential for railway infrastructure. Notable examples include A1 for Carbon Steel Tee Rails and A2 for Carbon Steel Girder Rails.

Structural Steel Applications

Standards addressing construction and building applications, such as A6/A6M for general requirements of rolled structural steel and A36/A36M for carbon structural steel, form a crucial category for the construction industry.

Spring Steel Specifications

Multiple standards address various spring steel applications, from A227/A227M for cold-drawn mechanical springs to A229/A229M for oil-tempered mechanical springs.

Standard Status Categories

• Active: Current standards in regular use
• Withdrawn: Standards no longer in effect (with withdrawal date noted)
• Replaced: Standards superseded by newer versions (with replacement standard noted)
