The components primarily utilize cold-rolled steel, manganese steel, and stainless steel, achieving the following properties through material modification:
Corrosion resistance: Electrolytic surface treatment enables resistance to salt spray environments.
Compressive strength: Work hardening via stamping increases the yield strength of manganese steel by over 30%.
Formability: Carbon content is controlled within the 0.11%–0.19% range to ensure plastic deformation capability.
A 2023 patented technology forms a novel alloy by adding elements such as zinc, aluminum, and nickel to the iron base, achieving a tensile strength in the 850 MPa range.
The application of an electrostatic carbon fiber coating technology reduces component weight by 15% while maintaining equivalent rigidity.
