SS400 Japanese standard square tubing is a common type of structural carbon steel square tubing, widely used in construction, machinery manufacturing, bridge construction, and other fields. The "SS400" in its name represents the material grade in the Japanese Industrial Standard (JIS), where "SS" indicates general structural rolled steel, and "400" indicates a minimum tensile strength of 400 MPa. Square tubing refers to steel tubing with a square cross-section, possessing high bending and torsional resistance.
1. In terms of mechanical properties, SS400 square tubing has a yield strength of approximately 235 MPa and a tensile strength between 400-510 MPa. This strength level allows it to meet the requirements of most structural applications. The material also has a certain elongation, typically above 15%, indicating a certain degree of deformation capability.
2. In terms of chemical composition, SS400 square tubing mainly contains elements such as iron, carbon, manganese, and silicon. The carbon content is generally controlled below 0.3%, and the manganese content below 1.4%. This reasonable ratio of elements ensures the material's basic properties. It should be noted that the specific chemical composition may vary depending on the manufacturing process and requirements.
3. In terms of dimensions, GNEE produces SS400 square tubing in various sizes. Common side lengths range from 20mm to 400mm, and wall thicknesses are typically between 1.5mm and 16mm. Users can choose the appropriate size according to their actual needs. GNEE controls dimensional tolerances according to national standards or customer requirements.
4. Surface Treatment: SS400 square tubing can undergo various surface treatments depending on requirements. Common methods include hot-dip galvanizing, painting, and powder coating. These treatments improve the product's corrosion resistance and extend its service life. When selecting a surface treatment method, factors such as the usage environment and cost budget need to be considered comprehensively.
5. Application Areas: SS400 square tubing is mainly used in building structures, mechanical frames, and conveyor equipment supports. In the construction industry, it is often used as a component of steel structures in factories and space frames in stadiums. In the machinery manufacturing industry, it can be used to manufacture bases and support structures for various equipment.
