Car door and window parts: Car doors and windows also need to use dual-phase steel materials to improve their protective performance, especially key parts such as front door anti-collision beams, which need to use high-strength dual-phase steel such as HC250/450DPD+Z Material.

How is the front door anti-collision beam of HC250/450DPD+Z galvanized?

HC250/450DPD+Z steel is used as the anti-collision beam of the front door of the car, and the surface is usually treated by hot-dip galvanizing to improve the anti-corrosion performance of the steel and prolong the service life.

Hot-dip galvanizing is a method of covering the surface of steel with a zinc layer. The process mainly includes the following steps:

Pickling: remove oxides and dirt on the steel surface for subsequent treatment.

Soaking: Soak pickled steel in a hot-dip galvanizing bath containing zinc salts to allow it to react with liquid zinc.

Drying: Take out the galvanized steel from the immersion tank, and let it dry naturally or dry to make the zinc layer on the surface uniform and firm.

Through hot-dip galvanizing treatment, the surface of HC250/450DPD+Z steel can be covered with a uniform, dense and corrosion-resistant zinc layer, which can effectively improve the corrosion resistance and service life of the steel. At the same time, the galvanized layer can also improve the mechanical properties of the steel, increase the tensile strength and yield strength of the anti-collision beam of the front door of the car, and enhance its anti-collision ability.
