Description
What is ASTM A36 Steel Plate?
ASTM A36 steel plates are low-carbon structural steel plates commonly used in a wide range of structural applications. The A36 Material Specification developed by ASTM International specifies the mechanical properties and chemical composition required for structural steel. This low-carbon steel plate is commonly utilized in construction, bridges, shipbuilding, oil and gas industries, and general fabrication.
