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.
High-strength hull structural steel is divided into strength grades according to its minimum yield strength, and each strength grade is divided into A, D, E, F4 grades according to its impact toughness.
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°
The marine ship building steel sheets is mainly used for producing boats body and decks. This kind steel is good at preventing hull from being corroded by chemical corrosion, electrochemical corrosion and sea life and microorganisams.
Our company can provide relevant quality inspection certificates such as SGS, MTC, etc., to serve you with the best quality, large warehouse and competitive price.
