CR420/780DP Purpose: Used for automotive structural components, stiffeners, and some inner and outer panels.
Automotive structural components: The high strength and high plasticity of duplex steel plates make them the preferred material for automotive structural components, such as doors, roof, underbody, front and rear bumpers, etc.
Airbag container: Dual phase steel plate has high strength and good formability, which can be made into a airbag container to ensure the effectiveness and stability of the airbag.
Motorcycle frame: Dual phase steel plate has high strength, high stiffness, and excellent formability, suitable for manufacturing components such as motorcycle frames.
Engineering machinery: The high strength and wear resistance of dual phase steel plates are suitable for components such as tires and tracks in the manufacturing of engineering machinery.
Home appliance products: The high strength and corrosion resistance of duplex steel plates are suitable for components such as the body and casing in the manufacturing of home appliances.
