SS400 Steel Pipe

SS400 Hollow Section Steel pipe is a Japanese standard steel, which is equivalent to Chinese Q235 steel. It includes rectangular hollow section steel pipes and square hollow section steel pipes.

Product Specification

SS400 Steel Tube is a kind of carbon structural steel pipe with a yield strength of 400MPa. According to the Japanese standard JIS G3101, SS400 is one of the most commonly used steel grades for general structural purposes.

The chemical composition of SS400 Steel Tube includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), and trace amounts of other elements. The maximum percentage of carbon is 0.22%, while the maximum percentage of manganese is 1.60%. The minimum percentage of phosphorus is 0.050%, and the minimum percentage of sulfur is 0.050%. The trace amounts of other elements include copper (Cu), chromium (Cr), nickel (Ni), and molybdenum (Mo).

The mechanical properties of the SS400 Steel Tube are as follows: a tensile strength of 400-510 MPa, a yield strength of 235 MPa, and an elongation of 21%. These properties make SS400 Steel Tube suitable for various applications in different industries.

The SS400 Steel Tube has several advantages over other types of steel pipes. It has a high strength-to-weight ratio, which means that it is strong and lightweight. It is also resistant to corrosion and abrasion, making it ideal for use in harsh environments. Additionally, it is easy to weld and machine, which makes it a popular choice for fabricators.

The SS400 Steel Tube is commonly used in the construction industry for building frames, bridges, and other structures. It is also used in the automotive industry for manufacturing exhaust systems, fuel lines, and other components. Other applications include furniture, pipelines, and machinery.
