Dang Steel, a reputable manufacturer and supplier located in Da Nang, Vietnam, is dedicated to delivering top-notch High Carbon Steel C55 Sheets and Plates. Renowned for their exceptional hardness, strength, and durability, these steel products are in high demand across industries that require tough materials for heavy-duty tasks. Dang Steel prides itself on precision manufacturing that meets international standards, providing sheets and plates that perform excellently under stress, wear, and fatigue. With state-of-the-art processing facilities, prompt delivery, and competitive pricing, Dang Steel is a dependable partner for industrial clients seeking C55 steel solutions both locally and globally.
High Carbon Steel C55 Sheets and Plates generally consist of carbon (0.50–0.60%), manganese (0.60–0.90%), along with small amounts of silicon, sulfur, and phosphorus. This blend results in high tensile strength, remarkable hardness, and impressive wear resistance. The steel boasts a tensile strength of 600–850 MPa, Brinell hardness between 170–210 HB, and good toughness when properly heat-treated. While it’s not as weldable as low-carbon grades, C55 steel excels in machinability and dimensional stability. Its strength and surface hardness make it ideal for applications that demand durability and resistance to mechanical wear under dynamic loading conditions.
