Balanced Mechanical Properties
Yield Strength: 350-550 MPa, meeting general structural load-bearing requirements.
Tensile Strength: 650-880 MPa, balancing strength and ductility.
Elongation: 8-25%, ensuring resistance to brittle fracture under deformation and suitability for cold forming processes.
Fatigue Strength: 275 MPa, suitable for environments subject to cyclic loading.
Excellent Processability
Cold/Hot Rolling Adaptability: Higher surface precision can be achieved through cold rolling, while hot rolling is employed for mass production of thick plates.
Superior Weldability: Low carbon content reduces the risk of welding cracks, eliminating the need for complex preheating treatments.
Cutting and Stamping Performance: The material's moderate hardness facilitates easy drilling, cutting, and stamping operations.
Diverse Surface Treatment Options
Corrosion Protection: Treatments such as galvanizing, painting, or electrophoretic coating can extend outdoor service life.
Bright/Black Surface Finishes: Selection depends on application requirements; bright finishes are ideal for direct processing, while black finishes retain an oxide layer for rust prevention.
