High Carbon Steel C55 Sheets and Plates are made primarily from carbon steel, containing around 0.55% carbon, along with manganese and trace amounts of other alloying elements. This specific blend results in high hardness, impressive tensile strength, and notable wear resistance. While these sheets and plates have less ductility compared to low-carbon steels, they excel in applications that demand rigidity, strength, and the ability to maintain shape under heavy loads. They can also undergo heat treatment processes, which further enhance their hardness and mechanical performance.
