High strength:Generally, the yield strength is above 300 Mpa.

High toughness: the elongation is required to be 15% - 20%, and the impact toughness at room temperature is greater than 60J / cm2. For large welded components, higher fracture toughness is required

Good weldability: Because of its low carbon content, less alloy elements, good plasticity and low hardenability, it is not suitable to appear quenching structure or crack in the weld.

Good cold and hot pressure processing performance.:Because of its good plasticity and small deformation resistance, it is not easy to crack after pressure processing.

Good corrosion resistance: It has higher corrosion resistance than carbon steel under various atmospheric conditions.
