SS400 steel: a common general structural steel widely used
Main properties of SS400 steel
Chemical composition: The chemical composition of SS400 steel is relatively simple, mainly composed of iron (Fe), carbon (C), and contains a small amount of manganese (Mn), silicon (Si), phosphorus (P) and sulfur (S).
Its low alloy composition makes it easy to process and weld, while maintaining sufficient strength and toughness.
Mechanical properties: Tensile strength: The minimum tensile strength of SS400 is 400 MPa, which can meet the strength requirements of most common structural parts. Yield strength: The yield strength of SS400 is about 245 MPa, which has good resistance to deformation. Elongation: The elongation of SS400 is high, usually exceeding 17%, indicating that it has good plasticity and toughness.
Processing performance: 40U steel is easy to cut, bend, weld and weld, suitable for a variety of processing techniques, and has good mechanical properties. Weldability makes it widely used in construction and manufacturing industries.
Corrosion resistance: S40 steel is generally corrosion-resistant, so it needs to be properly treated with anti-corrosion treatment according to environmental conditions, such as painting or galvanizing.
Construction Industry - SS400 steel is widely used in building structural components such as steel beams, steel columns, brackets and stairs. Its high strength and good processability make it an ideal choice for the construction industry.
