BBN Steel supplies carbon marine steel plates designated AH32 and DH32 for shipbuilding applications. These plates conform to ASTM A131 and carry certifications from ABS, DNV, LR, GL, BV, NK, KR and RINA. The material composition is limited to a maximum of 0.18 % carbon, 0.50 % silicon, 0.90‑1.60 % manganese, 0.035 % phosphorus and sulfur, 0.20 % chromium, 0.08 % molybdenum, 0.40‑0.80 % nickel and 0.35 % copper. Mechanical properties include a minimum yield strength of 315 MPa, tensile strength between 440‑570 MPa and elongation of at least 22 %. Impact testing shows suitability down to zero degrees for AH32 and to - 20 °C for DH32.
The plates are offered in a range of thicknesses from 6 mm to 25 mm, which is typical for marine hull construction. Standard dimensions are supplied in 2 m × 6 m sheets, a common size in the industry. Surface preparation follows ISO 8501‑1 standard blast cleaning to Sa 2.5, a typical requirement for marine steel. BBN Steel can apply normalising heat‑treatment such as Z15, Z25 or Z35, and optionally zinc‑shop‑primer paint, aligning with standard marine coating practices.
Shipyards building vessels over 10 000 tons and offshore platform fabricators are the primary buyers of these plates. BBN Steel maintains three warehouses in Zhengzhou, Shanghai and Tianjin with a combined stock of roughly 10 500 tons, allowing rapid dispatch. Each plate is shipped with an EN 10204‑3.2 mill test certificate and can be inspected by a third‑party agency before loading.

The company specialises in exporting shipbuilding steel plates that meet ASTM A131 and carry multiple classification society approvals. Each plate is hard‑stamped with heat number, batch number, material grade and size, and is shipped together with an EN 10204‑3.2 mill test certificate. BBN Steel can arrange third‑party inspection and offers optional surface treatments such as normalising and zinc‑shop‑primer painting.
AH32 and DH32 are high-strength marine steel plates widely used in ship hull construction and offshore structural applications. These shipbuilding steel plates comply with ASTM A131 specification and are certified by major classification societies including ABS, DNV, LR, GL, BV, NK, KR, and RINA. The plates offer excellent weldability and impact toughness at low temperatures, making them suitable for ocean-going vessel hulls and marine engineering structures. Exported globally with Mill Test Certificate and third-party inspection available.

Before placing an order, verify the grade (AH32 or DH32), request the full chemical analysis report and confirm that the mill test certificate complies with EN 10204‑3.2. Asking for a sample of the surface finish or a recent inspection report can further assure that the material meets your project specifications.
Logistics should be coordinated with BBN Steel’s warehouses in Zhengzhou, Shanghai or Tianjin. Confirm the preferred Incoterm - FOB or CIF - and discuss expected lead times, which depend on stock availability and shipping route. Payment terms are typically negotiated directly with the supplier and may include a letter of credit or advance payment, so clarify these details before finalising the contract.
Arrange a third‑party inspection covering visual checks, non‑destructive testing and dimensional verification upon arrival. Documentation such as the mill test certificate, classification society approval and any additional quality certificates should be reviewed before acceptance. Maintaining these controls helps ensure the steel plates meet the stringent requirements of marine construction.
