EN 10346 is a European standard for the technical requirements and testing methods of various types of steel sheets and strips. HCT780C-Z is a type of high-strength, hot-dip galvanized steel sheet commonly used in automotive manufacturing, construction, and mechanical engineering. The "HCT" designation represents high-strength steel sheet, "780" indicates a minimum yield strength of 780 MPa, "C" denotes a carbon-manganese steel, and "Z" stands for zinc coating.
HCT780C-Z features excellent corrosion resistance and good weldability, making it ideal for use in harsh environments. Its high strength and formability allow for greater design flexibility in the production of automotive components, such as chassis, structural members, and reinforcements. This type of steel sheet is also used in the construction of high-strength pipelines, bridges, and other infrastructure.
