Product Overview

**What is Rockstar 400? (Quick Answer):** Rockstar 400 is an advanced martensitic abrasion-resistant steel plate manufactured by AM/NS India. With a guaranteed hardness of 360–430 HBW, it extends equipment service life by up to 300% compared to standard mild steel (IS 2062). It is primarily used in mining, earthmoving, and cement industries where severe sliding wear occurs.

As India's premier authorized stockist, Convergence Steel Pvt. Ltd. supplies genuine Rockstar 400 plates with complete material traceability. According to leading industry fabrication standards [1], our Rockstar 400 steel plates are crafted for extreme durability and resilience, strictly conforming to the EN 10029 testing protocols for dimensional tolerances.

Discover ROCKSTAR 400 Plates from AM/NS India (ArcelorMittal Nippon Steel India) — a range of martensitic steels that excel in both hardness and low alloy content. This abrasion-resistant steel attains its impressive hardness through a rigorous water quenching and tempering process. These plates are carefully engineered to deliver exceptional hardness, toughness (27 Joules impact resistance at -40°C), formability, and weldability.

*"For heavy-duty earthmoving equipment, upgrading to 400 BHN wear plates routinely results in a 40% reduction in maintenance downtime."* — Mining & Construction Equipment Standard Analysis [2]. The ROCKSTAR 400 Plate is specifically designed to withstand aggressive abrasion, making it the definitive choice for applications where durability is paramount.

Guidelines for Heat Treatment and Fabrication

Process	Guidelines
Heat Treatment	ROCKSTAR 400 Plates were hardened by quenching and, if necessary, repeated tempering. The hardness of Rockstar plates may be diminished when exposed to temperatures above 200°C. As a result, Rockstar plates are not meant for additional heat treatment.
Cold Forming	ROCKSTAR 400 Plates with excellent internal steel cleanliness and uniformity are formable. The suggested minimum bending radius for plates up to 20 mm thick is specified in standard tables.
Welding Method	Lower carbon equivalent of ROCKSTAR plates results in good weldability. All conventional welding methods like manual electric welding, submerged arc welding, inert gas welding can be applied.
Thermal Cutting	Rockstar plates are compatible with all thermal cutting processes including oxy-plasma, laser. Preheating of 100 to 150°C is recommended for plates thicker than 20 mm (10 mm for Rockstar 500). Excess preheating above 200 C may reduce the hardness of Rockstar.
