A633 Carbon Steel Plate

ASTM A633 steel includes four grades: A, C, D, and E, of which the thickness of grade C can reach 4 inches and the thickness of grade E can reach 6 inches. ASTM A633 steel specification is based on the standard specification for standardized high-strength low-alloy structural steel plate, which requires high notch toughness under low temperature conditions.
