Technical | Hot rolled | ||
Thickness tolerance | ±0.15mm | ||
Application | To prevent the hull from being corroded by chemical corrosion, electrochemical corrosion and sea life and microorganisms.It is used in make ship body ,decks etc. | ||
Due to the harsh working environment of the ship, the hull shell is subject to chemical corrosion of seawater, electrochemical corrosion and corrosion of marine organisms and microorganisms; the hull is subjected to large wind and wave impacts and alternating loads; the shape of the ship is complicated by processing methods, etc. Steel for hull structure is strictly required. First of all, good toughness is the most critical requirement. In addition, high strength, good corrosion resistance, weldability, forming properties and surface quality are required.
For marine steel plate, China Classification Society standard is three strength grades and four quality grades.
The yield strength of A36, D36, E36 and F36 is not less than 355N/mm^2, and the tensile strength is 490~620N/mm^2. A, D, E and F respectively indicate that they can be at 0° and -20° respectively. Impact toughness that can be achieved at -40°, -60°
