Liam Steel, based in Manila, Philippines, is a reputable manufacturer and supplier known for its top-notch High Carbon Steel C55 Sheets and Plates. These products are crafted for outstanding hardness, strength, and wear resistance, making them perfect for applications that require high surface durability and robust mechanical strength. With a commitment to advanced technology and rigorous quality control, C55 Steel Sheets and Plates find their place in various sectors, including industrial, automotive, and engineering. Liam Steel guarantees consistent quality, precise dimensions, and timely delivery, establishing itself as a dependable partner for industries in need of durable, high-performance carbon steel materials for heavy-duty and precision manufacturing tasks.
High Carbon Steel C55 Sheets and Plates are primarily made up of carbon (0.50–0.60%), manganese (0.60–0.90%), and silicon (0.15–0.35%), along with small amounts of phosphorus and sulfur. This specific blend gives the steel its notable hardness and strength after undergoing heat treatment. It boasts a tensile strength ranging from 700 to 850 MPa and a yield strength of about 400 MPa, along with excellent wear resistance and moderate toughness. C55 steel can be hardened and tempered to achieve the desired mechanical properties, making it ideal for producing components that need high surface hardness and dimensional stability.
