JIS G3106 SM400A is a low-carbon structural steel, belonging to the hot-rolled steel in the Japanese Industrial Standards (JIS), widely used in buildings, bridges, ships, vehicles, and other structural components.
Mechanical Properties: It has good ductility. Stable performance, suitable for structural applications requiring medium strength.
Welding Performance: Due to its low carbon equivalent, SM400A has excellent welding performance, suitable for various welding methods (such as manual arc welding, gas shielded welding, etc.), without preheating or only requiring slight preheating.
Processing Performance: Easy to cut, form, and process, suitable for cold bending and hot working.
Corrosion Resistance: As an ordinary low-carbon steel, SM400A has general corrosion resistance, and protective measures are needed when exposed to humid or corrosive environments.
Other Characteristics: Good toughness and impact resistance, suitable for use in normal temperature environments. Relatively low cost, high cost-effectiveness.
