High strength: Generally, the yield strength is above 300MPa.
High toughness: The elongation is required to be 15%-20%, and the room temperature impact toughness is greater than 60J/cm2. For large welded parts, higher fracture toughness is required
Good weldability: Due to its low carbon content, less alloying elements, good plasticity, and low hardenability, it is not suitable for quenched structure or cracks in the weld.
Good cold and hot pressing performance: good plasticity, low deformation resistance, and not easy to crack after pressure treatment.
Good corrosion resistance: It has higher corrosion resistance than carbon steel under various atmospheric conditions.
