ASTM A283 Steel Plate

ASTM Steel is Recommended for 

Industrial and commercial structures, cabinets, enclosures and housings.

ASTM A283 is a low carbon steel that is strong and formable.

It is easy to machine and fabricate and can be securely welded by all welding methods.

ASTM A283 steel plate is used in riveted, bolted, and welded construction of bridges and buildings, and for buildings, including pre-fabricated buildings, warehouses, and industrial and commercial structures

As an ASTM A283 supplier, we will be glad to help you select the product that best suits your needs.


Two grades (C and D) for structural and general uses. ASTM A283 is a carbon steel for forming. It has a slightly higher ductility and a slightly lower strength than A36.

ASTM A283 Specifications 

  • Strength, Yield Strength ksi (MPa), Tensile Strength ksi (MPa): Strong, 65 (380-550)
    For higher strength and lower weight, consider High-strength, Low-alloy

  • Formability: % Elongation: Better, 23-25%
    For better formability consider Drawing Steel

  • Joining – Very Good
    The cheapest and easiest methods can be used: shielded metal arc welding (SMAW, or stick welding), gas metal arc welding (GMAW, or MIG welding), and oxyacetylene welding.  A283 steel is also commonly bolted and riveted for buildings and other structures.

  • Corrosion Resistance – Good
    Galvanized ASTM 283 will rust more slowly.  For longer life in harsh chemical conditions, consider Galvanized or Coated Steel

  • Chemistry A283 is a ‘plain’ steel without expensive alloying elements.

  • Cost – Relatively low. 
    Good when thinner, stronger, or more formable steels will not add value.
