Angle Steel Bar SS400 JIS
When purchasing and using this kind of angle bar, it is very important to understand its material characteristics and specifications.
Chemical Composition
The chemical composition of SS400 steel angle bar should comply with the regulations of JIS G 3112. Its main components include iron (Fe), carbon (C), silicon (Si), manganese (Mn) and other elements. Among them, the carbon content should be between 0.18%-0.28%, the silicon content should be between 0.12%-0.30%, and the manganese content should be between 0.70%-1.00%. In addition, angle steel should also contain certain elements of phosphorus (P) and sulfur (S) to increase its hardness and strength.
The mechanical properties of SS400 profile steel should comply with the regulations of JIS G 3112. Its tensile strength (σb) should not be less than 400N/mm², and its yield strength (σs) should not be less than 240N/mm². At the same time, the elongation (δ) of the hot rolled steel angle bar should not be less than 22%. These mechanical properties ensure that SS400 angle steel has high load-bearing capacity and durability in various application scenarios.
Mechanical Properties
Process performance
SS400 equal angle has good process performance and can be used for bending, straightening, shearing, stamping and other processing operations. At the same time, this kind of hot rolled steel profiles also have good welding performance and can meet various welding requirements. During the processing, attention should be paid to controlling the temperature and cooling rate to avoid cracks and deformation of the angle steel.
Corrosion Resistance
SS400 angle steel has certain corrosion resistance, but is prone to rust in humid environments. In order to improve its corrosion resistance, the surface of the angle steel can be coated with a layer of anti-rust paint. In addition, during transportation and storage, the angle steel should be kept dry and clean to avoid prolonged exposure to moisture.
In short, Japanese standard angle steel SS400 is a high-quality angle steel that is widely used in various construction, bridges, ships, automobiles and other fields. It is very important to understand its material properties and specifications when purchasing and using this type of angle steel. During use, attention should be paid to maintenance and upkeep to ensure its safety and service life.
