SS400 Black Steel Plates refer to the black - colored steel plates of the SS400 grade, which are common carbon structural steel plates specified in the Japanese Industrial Standard (JIS G3101)1. The relevant introduction is as follows:

 

 

Mechanical Properties: The minimum yield strength is usually ≥245MPa (it may vary depending on the thickness of the steel plate, for example, when the thickness is less than 16mm, the yield strength is ≥245MPa). The tensile strength is between 400MPa and 510MPa, the elongation is ≥26%, and the impact energy is ≥27J.

Physical Characteristics: It has good weldability, which is convenient for welding and other processing operations. It also has good cold - working performance and can be easily cut, bent, etc. However, its corrosion resistance is relatively poor, and appropriate anti - corrosion treatment may be required.

 

 

 

 

 

 

Production Process: It mainly includes smelting (using electric furnaces or converters, and adding appropriate alloying elements), continuous casting (pouring the molten steel into a continuous casting machine to form a billet), rolling (sending the billet to a rolling mill to obtain steel plates of different specifications), surface treatment (such as rust removal, painting, etc.).

Application Fields: Widely used in construction (such as steel - structure frames, beams, columns), machinery manufacturing (such as bearings, gears, transmission shafts), bridge engineering (such as bridge decks, piers), vehicle manufacturing (such as vehicle chassis, frames), petrochemical and other fields.
