ASTM A131 Ship Building Steel Sheet.Ship building steel sheet refers to the thin steel sheet and thick steel plate produced with special structural steel for shipbuilding and used to manufacture the hull structure of ships sailing in ocean, coastal and inland waterways. Structural steel for shipbuilding includes low-alloy steel and carbon steel, and the end of the steel number is marked with C (boat). Carbon steel has 2C, 3C, 4C and 5C, and low alloy steel has 12MnC, 16MnC, 15MnTiC, 14MnVTiReC and other steel grades. The thickness is 2.5~50mm. Ship plate steel grades include A, B, D, E grades of general strength and AH32, DH32, EH32, AH36, DH36, EH36 grades of high strength; A and B ship plates of general strength can meet the requirements of Due to the requirements of technology and mechanical properties, the production process is relatively simple; while the production of D, E and high-strength ship plates needs to be realized by means of controlled rolling and controlled cooling process or heat treatment process with relatively complete equipment and equipment. At the same time, the internal steel purity requirements of the supplied billets are relatively high, especially the content of S, P, N, 0, H, etc. in the steel must be strictly controlled.

The steel plate is a flat steel that is cast with molten steel and pressed after cooling.
The steel sheet is flat, rectangular and can be directly rolled or cut from wide steel strips.
The steel plates is divided according to the thickness, the thin steel plate is less than 4 mm (the thinnest is 0.2 mm), the medium-thick steel plate is 4-60 mm, and the extra-thick steel plate is 60-115 mm.
Steel sheets are divided into hot rolling plate and cold rolling plate according to rolling.
1. Hot Rolled Steel Plate
Hot rolling processing methods include hot rolling, forging, extrusion and other methods.
2. Cold Rolled Steel Plate
Cold rolling processing methods include cold rolling, cold drawing and cold drawing, cold bending, cold extrusion and other methods.
The cold rolling method is to continue processing the hot rolled steel below the recrystallization temperature to make it cold rolled steel. Using cold rolling processing method can improve the mechanical properties of steel, and obtain products with high dimensional accuracy and certain smoothness.
