Latham Steel, a well-respected manufacturer and supplier based in Hamilton, New Zealand, specializes in high-strength Rockstar 450 sheets and plates. These products are crafted for exceptional wear resistance and a long service life, even in the toughest industrial settings. Rockstar 450 is a quenched and tempered abrasion-resistant steel that boasts impressive hardness, excellent impact toughness, and reliable dimensional stability. Latham Steel is committed to maintaining strict quality control, ensuring precise thickness tolerances and a uniform surface finish on all plates. Perfect for heavy-duty applications that face constant abrasion and impact, Rockstar 450 is a dependable, cost-effective choice that enhances equipment longevity and boosts productivity in challenging environments.
Rockstar 450 steel is formulated with a blend of carbon, manganese, chromium, nickel, and molybdenum to achieve its remarkable hardness and wear resistance. It typically reaches a nominal hardness of around 450 HBW, thanks to advanced quenching and tempering techniques. This steel offers high tensile strength, excellent impact resistance, and robust protection against cracking and deformation under heavy loads. Its refined microstructure ensures consistent hardness throughout the plate. While it’s highly wear-resistant, Rockstar 450 also retains good weldability and formability when proper procedures are followed, making it ideal for crafting heavy-wear components.
