ROCKSTAR Abrasion Resistant Steel is a high-performance product from JSW Steel, designed to meet the rigorous demands of the mining, construction, and material handling industries. Available in specialized grades including ROCKSTAR 400, 450, and 500, these plates are manufactured using a state-of-the-art quenching and tempering process at JSW's advanced facilities. This process ensures that the plates possess a fine-grained microstructure, providing a perfect synergy of high surface hardness and exceptional internal toughness. ROCKSTAR is specifically engineered to resist the severe wear caused by the impact and sliding of hard minerals, significantly reducing the frequency of equipment failure.

The versatility of JSW ROCKSTAR 400/450/500 lies in its superior workshop-friendly characteristics. These plates are developed with a controlled chemical composition that ensures excellent weldability and easy cold-forming, allowing for the fabrication of complex structural components without compromising material integrity. Because of its high strength, ROCKSTAR enables the design of lighter equipment that can carry higher payloads, thereby optimizing fuel efficiency and reducing operational costs. It is the preferred choice for liner plates, crusher parts, excavator buckets, tipper bodies, and conveyors, offering a reliable and cost-effective solution for India's infrastructure and industrial sectors.



ROCKSTAR 400/450/500 Plates Features

  • » Indigenous Engineering Excellence: Developed by JSW Steel, ROCKSTAR represents India's premier homegrown solution for extreme abrasion resistance, tailored for local industrial conditions.
  • » High Surface & Core Hardness: Precision quenching and tempering ensure the Brinell hardness is maintained consistently from the surface to the core, providing uniform wear protection throughout the plate's life.
  • » Superior Impact Energy Absorption: Engineered with a fine-grained microstructure that allows the plates to withstand heavy shock loads and impacts without cracking, even in high-stress mining environments.
  • » Workshop Friendly (Easy-Weld): Formulated with a low carbon equivalent to ensure excellent weldability using standard techniques, significantly reducing the risk of heat-affected zone (HAZ) softening.
  • » Excellent Bendability: Despite its high hardness, ROCKSTAR offers superior cold-forming properties, allowing for easy folding and bending into complex shapes like excavator buckets and tipper bodies.
  • » Enhanced Equipment Payload: The high strength-to-weight ratio allows for the use of thinner plates without sacrificing durability, leading to lighter machinery and higher operational efficiency.
  • » Predictable Service Life: Designed to last 3 to 4 times longer than standard structural steels, effectively minimizing maintenance downtime and lowering the total cost of ownership.
  • » Strict Quality Control: Every plate undergoes rigorous testing for flatness, dimensional accuracy, and ultrasonic integrity to ensure compliance with international AR steel standards.
