Core performance characteristics of Docol 460HE

1. High strength foundation

Referring to the performance standards of similar high-strength steels (such as AH460), it is speculated that the yield strength of Docol 460HE is not less than 460MPa, and the tensile strength may be in the range of 550-700MPa, which meets the requirements of automotive structural parts for load-bearing capacity.

2. Excellent edge ductility

As a "high edge ductility" steel, it still maintains good plasticity in the edge area after punching, shearing and other processing, which can reduce the risk of cracking caused by stress concentration during the forming process, and is especially suitable for the cold stamping process of complex shape parts.

3. Good welding and formability

Advanced alloy design (such as low carbon + micro-alloying elements) may be adopted to support conventional welding processes such as arc welding and laser welding, and the strength loss of the welded joint is small; the yield strength ratio is low and the work hardening rate is reasonable, which is convenient for cold forming of complex geometric shapes.

4. Balance between lightness and safety

By improving the strength of the material, the thickness of the components can be reduced (10%-30% lighter than ordinary steel), while ensuring the collision energy absorption capacity, which is in line with the development trend of "lightweight and safety in parallel" in the automotive industry

Typical application scenarios of Docol 460HE

1. Automotive safety structural parts

Anti-collision beams and door anti-collision bars: use high strength and edge ductility to effectively absorb energy in collisions and reduce the risk of component breakage.

Chassis components: such as longitudinal beams and cross beams, which must meet the requirements of both load-bearing strength and molding process.

2. Precision machining field

Applicable to components with high requirements for edge accuracy and fatigue resistance, such as gears, transmission shafts, etc., and improve production efficiency through cold processing.

3. Potential expansion areas

Referring to the application scope of AH460, it may extend to bridges, marine engineering and other fields in the future, and its corrosion resistance and low-temperature toughness performance need to be further verified.
