The hardness requirements of electrogalvanized steel sheets vary according to different application scenarios. For example, the automotive and home appliance industries have higher hardness requirements for steel sheets, because the components used in these fields need to have better wear resistance and tensile strength; in the construction field, since steel sheets are mainly used for structural frames, the hardness requirements are relatively low.

‌The hardness of the galvanized sheet depends on the material and thickness of the base material and the thickness of the zinc layer. ‌

The hardness of the galvanized sheet is mainly affected by the following factors:

‌Material and thickness of the substrate‌: The material and thickness of the substrate are the key factors that determine the hardness of the galvanized sheet. Generally speaking, the harder the substrate, the harder the electro-galvanized steel sheet produced.
‌Thickness of the zinc layer‌: The thickness of the zinc layer is also an important factor affecting the hardness of the galvanized sheet. The thicker the zinc layer, the higher the hardness.
‌Heat treatment and external force impact during processing‌: Factors such as heat treatment and external force impact during processing will also affect the hardness of the electro-galvanized steel sheet.
The hardness requirements of electro-galvanized steel sheets are also different for different application scenarios. For example, industries such as automobiles and home appliances have higher requirements for the hardness of steel plates, because the components used in these fields need to have better wear resistance and tensile strength; in the construction field, since steel plates are mainly used for structural frames, the hardness requirements are relatively low. ‌
