Rockstar 450 sheets and plates are designed to withstand abrasion, featuring quenched and tempered martensitic steel that excels in tough, wear-heavy environments. With a hardness range of **425–475 BHN**, they strike a balance between hardness and toughness, along with excellent weldability and formability — making them a top choice for heavy-duty and abrasive applications. ([bhaveshsteel.ae][1])
The typical chemical makeup of Rockstar 450 includes carbon (up to ~0.30 %), manganese (max ~1.60 %), silicon (max ~0.70 %), chromium (up to ~1.00 %), nickel (up to ~0.60 %), molybdenum (up to ~0.60 %), and trace amounts of phosphorus, sulfur, and boron — varying with thickness — to ensure the necessary hardness and wear resistance while maintaining weldability. ([saisteelengg.com][2]) In terms of mechanical properties, a 20 mm plate usually shows a yield strength of about **≈ 1150 MPa**, tensile strength around **1350 MPa**, elongation of roughly 12%, and retains good impact toughness even in subzero conditions (e.g., ~30 J at –20 °C).

Thanks to these impressive characteristics, Rockstar 450 sheets and plates are widely utilized in heavy-duty and wear-prone settings: from mining and construction machinery (like buckets, excavators, and dump-truck liners) to crushers, chutes, hoppers, conveyor systems, concrete-mixing drums, and other industrial equipment that faces abrasion, impact, and heavy wear.
