SS400/SS330 JIS Black Carbon Steel Coil
In the grade of Japanese steel (JIS series), ordinary structural steel is mainly composed of three parts: the first part indicates the material, the second part indicates different shapes, types, uses, and the third part indicates the characteristic number, which is generally the lowest tensile strength. For example: SS400 - the first S means Steel, the second S means "Structure" (Structure), 400 tensile strength lower limit of 400MPa The same way SS330 means tensile strength of 330MPa

Product details

ss400 is a kind of marking method of Japanese steel material and a kind of judging standard. Foreign standard structural steel is often classified by tensile strength, such as SS400 (Japan is so marked), of which 400 means that the minimum value of σb is 400MPa Ultra-high strength steel refers to σb≥1373 Mpa steel.Due to moderate carbon content, good comprehensive performance, strength, plasticity and welding properties have been better matched, the most widely used.

SS330 is a kind of high strength, corrosion resistance and wear resistance steel, because of its excellent properties, it is widely used in machinery manufacturing, construction engineering and shipbuilding. The tensile strength of SS330 is as high as 400-540 mpa, which is a high-strength steel with good mechanical properties. At the same time, SS330 has good plasticity and toughness, which can meet different material processing and process requirements.

SS490 is a hot-rolled pickling steel strip widely used in general structural applications. It is known for its exceptional strength, durability and versatility and is suitable for a variety of construction projects. SS490 is produced by a hot rolling process and then pickled to remove surface impurities and oxide layers, resulting in a clean and smooth surface finish. This steel strip has good weldability, machinability and formability, and is easy to manufacture and assemble.

SS490 Chemical composition:

(C) : up to 0.22%, (Si) : up to 0.25%, (Mn) : up to 1.40%, (P) : up to 0.035%, (S) : up to 0.035%

SS490 Mechanical Properties:

Tensile strength: 490-610 MPa

Yield strength: minimum 275 MPa

Elongation: minimum 16%

These values indicate the strength and ductility of SS490. The steel strip shows moderate tensile strength, which refers to its ability to resist tension without breaking. Yield strength represents the level of stress at which a material begins to permanently deform, while elongation measures the amount of deformation a steel can withstand before it fails.
