Aatir Steel is a well-respected manufacturer and supplier of High Carbon Steel C55 Sheets and Plates, proudly based in Cairo, Egypt. The company is committed to delivering top-notch steel products that blend strength, precision, and durability, perfect for demanding industrial applications. Aatir Steel’s C55 Sheets and Plates are crafted to meet international quality standards, providing outstanding hardness and wear resistance. With a strong emphasis on advanced processing techniques and ensuring customer satisfaction, Aatir Steel caters to various industries, including engineering, automotive, construction, and machinery manufacturing, guaranteeing long-lasting performance and reliability in every product they offer.
High Carbon Steel C55 Sheets and Plates are made from iron with a carbon content of around 0.55%, along with trace amounts of manganese, silicon, phosphorus, and sulfur. This medium-to-high carbon mix boosts hardness, tensile strength, and wear resistance while still allowing for good machinability. After undergoing proper heat treatment, C55 Sheets and Plates achieve remarkable surface hardness and mechanical stability. They exhibit moderate toughness and limited weldability, making them perfect for components that need to withstand high strength and resist deformation under stress or impact in heavy-duty applications.
