ASTM Standard Carbon Steel Plate Supplier | Diverse Thickness Options

ASTM standard carbon steel plates conform to specifications set by the American Society for Testing and Materials (ASTM), widely used in North America and internationally for projects adopting U.S. engineering standards. ASTM A36 is one of the most common standards for structural carbon steel plates, specifying a minimum yield strength of 250 MPa and tensile strength of 400 550 MPa, with good ductility and weldability. Other key standards include ASTM A572 for high strength low alloy steel and ASTM A516 for pressure vessel plates. Chemical composition control is rigorous, with limits on carbon (typically ≤0.29% for ASTM A36), manganese, phosphorus, and sulfur to ensure processability and performance. Mechanical properties are defined by tensile tests, yield point determination, and elongation measurements, with optional impact testing for toughness evaluation. ASTM plates are produced using various melting processes, including basic oxygen furnaces and electric arc furnaces, followed by hot rolling and, if necessary, heat treatment. They are widely used in construction (building frames, bridges), manufacturing (machinery bases), and infrastructure (highway components). The ASTM certification process ensures material consistency and traceability, with mill test reports provided for each batch. International projects often specify ASTM standards for compatibility with U.S. based design codes and ease of procurement, making ASTM standard carbon steel plates a global benchmark for quality and reliability.
