A283 Grade A steel is a low carbon steel grade specified under the ASTM A283 standard, widely recognized for its excellent weldability and moderate strength. This steel grade is primarily used in structural applications where high strength is not a critical requirement. 

A283 Grade A carbon steel offers a good balance of strength and ductility, making it suitable for low-pressure environments. Its low carbon content ensures easy formability and weldability, distinguishing it from higher-strength steel grades. this material is an ideal choice for fabrication projects requiring minimal heat treatment.

Chemical Composition of A283 Grade A

The chemical composition of A283 Grade A ensures its suitability for structural purposes with limited alloying elements. 

Element Carbon (C) Manganese (Mn) Phosphorus (P) Sulfur (S) Silicon (Si) Copper (Cu)
Content (%) ≤ 0.14 ≤ 0.90 ≤ 0.035 ≤ 0.040 ≤ 0.40 ≥ 0.20 (if specified)

Mechanical Properties of A283 Grade A

The mechanical properties of A283 Grade A make it suitable for moderate load-bearing applications.

Property Tensile Strength (MPa) Yield Strength (MPa) Elongation (%)
Value 310-415 ≥ 165 ≥ 27 (in 200mm)
