Luke Steel, located in Houston, Houstan, has built a solid reputation as a reliable manufacturer and supplier of top-notch High Carbon Steel C55 Sheets and Plates. They cater to a variety of industries, including automotive, engineering, toolmaking, and heavy machinery. With a focus on precision processing and strict quality control, Luke Steel provides C55 plates that consistently meet the high standards for strength, hardness, and machinability that these industries demand. Thanks to their cutting-edge facilities and dedication to customer satisfaction, they ensure that robust C55 sheets and plates are delivered on time, supporting essential projects that require high-performance steel with dependable quality.
High Carbon Steel C55 Sheets and Plates contain about 0.52–0.60% carbon and 0.60–0.90% manganese, which contribute to their impressive hardness, strength, and wear resistance. These plates typically boast a tensile strength ranging from 600–750 MPa and a yield strength of around 330 MPa. They also exhibit good toughness and can be heat-treated or surface-hardened for even greater hardness. The steel’s machinability and ability to be accurately formed or cut make it perfect for applications that require high durability and impact resistance.
