Samuel Steels, based in Abuja, Nigeria, has built a solid reputation as a reliable manufacturer and supplier of Rockstar 400 Sheets and Plates. These products are celebrated for their remarkable hardness, strength, and resistance to wear. Designed to thrive in tough conditions where durability and impact resistance are key, each sheet and plate from Samuel Steels is crafted to meet international quality standards. The company prides itself on delivering products that blend precision, toughness, and longevity. With state-of-the-art production facilities and a strong commitment to customer satisfaction, Samuel Steels serves various industries, including mining, construction, material handling, and heavy machinery, providing dependable and high-performance steel solutions.
Rockstar 400 Sheets and Plates are made up of a mix of carbon, manganese, chromium, nickel, and molybdenum, all of which contribute to their impressive hardness and strength. With a nominal hardness of 400 HBW, these plates offer excellent wear and abrasion resistance. Their tensile strength falls between 1250 and 1450 MPa, showcasing superior yield strength and impact toughness. A specialized heat treatment process gives the steel a fine-grain microstructure, enhancing its formability and machinability while keeping its hardness intact. These mechanical properties make Rockstar 400 perfect for environments that experience heavy impact and abrasive conditions.
