ASTM A606/A606M-23 PDF

Full title and description

Standard Specification for Steel, Sheet and Strip, High-Strength, Low-Alloy, Hot-Rolled and Cold-Rolled, with Improved Atmospheric Corrosion Resistance (ASTM A606/A606M-23). This specification defines chemical, mechanical, and product requirements for HSLA sheet and strip produced for structural and miscellaneous applications where improved atmospheric corrosion resistance (weathering) and strength are desired.

Abstract

This specification covers hot-rolled and cold-rolled high‑strength, low‑alloy steel sheet and strip supplied in coils or cut lengths, offered in Types (including Type 2, Type 4, Type 5) or as Commercial Steel (CS), with requirements for chemistry, tensile properties, elongation, surface condition, and testing. It also addresses weldability and the use of SI or inch‑pound units.

Scope

The specification applies to high‑strength, low‑alloy sheet and strip (hot‑rolled and cold‑rolled) in coils or cut lengths with ordered thicknesses across the ranges described in the standard, intended for structural and miscellaneous purposes where weight savings or enhanced durability are important. The steels covered have enhanced atmospheric corrosion resistance and are furnished in specified Types or as Commercial Steel; the standard also clarifies unit systems, welding considerations, and testing requirements.

Key topics and requirements

• Chemical composition limits for carbon, manganese, phosphorus, sulfur and specified minimum copper and other alloying elements by Type (Type 2, Type 4, Type 5 and CS).
• Mechanical properties: minimum yield and tensile strengths and minimum elongation requirements specified for furnished product and grade (e.g., Type 4 grades commonly target ~50 ksi yield / ~70 ksi tensile for thicker hot‑rolled products, with lower values for some coil conditions — check the standard for exact grade/table values).
• Product forms and dimensional limits: coils and cut lengths; hot‑rolled vs cold‑rolled thickness ranges noted in the standard.
• Surface condition, edge condition, and testing requirements including tension testing and retest provisions.
• Guidance on weldability and the need to use suitable welding procedures based on composition and intended service.
• Reference to methods for establishing atmospheric corrosion resistance (see ASTM Guide G101) and related ASTM practices and appendices.

Typical use and users

Used by steel producers, coil and sheet fabricators, structural and civil engineers, architects specifying weathering/atmospheric‑resistant steels, procurement/specification writers, and industries requiring durable exterior steel (bridges, architectural facades, structural components, equipment housings). Producers and distributors also use the standard to confirm product properties for sale and supply.

Related standards

ASTM A606/A606M references and is often used alongside other ASTM specifications and guides for sheet and strip steels and weathering evaluation (for example, ASTM Guide G101 for atmospheric corrosion resistance assessment, and related sheet/strip specifications such as A6/A6M product definitions and other flat‑product standards). Users should consult ancillary ASTM product and testing standards for sampling, mechanical testing, and surface treatment requirements.
