SS400 is one of the most commonly used hot rolled general structural steel.SS400 steel plate, JIS3101 SS400 steel plate, under JIS3101 standard, we can regard SS400 steel plate as Carbon and low alloy steel SS400 steel plate is one mainly of Carbon and low alloy steel, SS400 steel plate would be used to built containers which can bear low temperature sea water.
SS400steel plate sheet is a kind of steel for general structure,and it is used in ship,house,bridge making and so on.This kind of steel plate sheet SS400 has some features,like its heat condition,excellent freezing,even structure with pressure resistance and its good mechanical properties.
This specification of SS400 steel plate covers carbon structural steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes.
Heat analysis shall be used to determine the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, and copper. Tensile strength, yield strength, and elongation shall be evaluated using tension test and must conform to the required tensile properties.SS400 is a Japanese standard steel whose material is 1.0037.
