RINA A420, D420.E420, F420, Steel Plate
The RINA A420, D420, E420 and F420 steel plates offered by Henan HZZ Iron and Steel Co., Ltd. are high‑strength hull structural steels certified by the Registro Italiano Navale for marine construction. Each grade provides a minimum yield strength of 420 MPa and impact toughness suitable for service temperatures down to - 60 °C. The plates are supplied hot‑rolled, with standard thicknesses from 6 mm to 150 mm and widths up to 4 000 mm. Mill test certificates accompany every shipment to confirm compliance with RINA specifications.
The alloy composition typically contains carbon 0.15‑0.20 %, manganese 0.5‑1.0 % and silicon up to 0.5 % to achieve the required strength and ductility, which is standard for marine hull steel. Tensile strength for these grades usually falls between 560 MPa and 680 MPa, providing a safety margin for structural loads. Surface treatment is applied to improve corrosion resistance in saltwater environments, a common practice for shipbuilding steel. Thickness tolerance of ±0.5 mm and flatness within industry standards ensure ease of welding and fitting on large vessels.
Shipyards, offshore platform constructors and naval repair facilities are the primary buyers of these plates. Henan HZZ can arrange FOB or CIF shipping from Zhengzhou, and the supplier notes flexible minimum order quantities to accommodate both prototype and bulk projects. Payment is typically handled via L/C or T/T, subject to confirmation with the supplier. Interested parties should request the latest mill test certificate and verify the grade code before finalising the order.
