As of early January 2026, the mainstream market quotation for AH36 high-strength marine steel plates is 680-750 US dollars per ton (FOB China). The specific price is affected by factors such as thickness, certification, and order quantity. For AH36 in controlled rolling state (ABS\/CCS certified) with conventional thickness (0.39-1.18 inches), the quotation is approximately 700-720 US dollars per ton; due to the high rolling difficulty, the price of thin-gauge products (0.24-0.31 inches) increases to 730-750 US dollars per ton; the quotation for thick plates (1.18-1.97 inches) is 680-700 US dollars per ton. Non-standard products without classification society certification are 10%-15% cheaper, at around 600-650 US dollars per ton. Bulk orders (\u2265100 tons) can enjoy a 3%-5% discount.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

AH-36 steel is an internationally recognized high-strength hull structural steel specifically designed for marine and offshore engineering. It complies with standards such as ASTM A131 and GB\/T 712, and holds certifications from major classification societies including ABS, BV, DNV, and CCS. In its designation, “A” denotes the quality grade, “H” stands for high strength, and “36” indicates a minimum yield strength of \u2265355MPa (approximately 36ksi). With a tensile strength of 490-630MPa, elongation \u226521%, and impact energy \u226534J at 0\u2103, it features excellent weldability (CET \u22640.40%) and adaptability to marine environments. Widely used in critical structures like hulls, decks, bulkheads, and offshore platforms, it enables 10%-15% structural weight reduction while ensuring the safe service of ships under complex sea conditions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t
