Rockstar 400 (Essar, India Make)

Abrasive resistant weldable steel plates have an excellent combination of hardness, abrasion resistance, formability, weldability, toughness and flatness to meet fabrication demands and application requirements. Designed for through- hardness, Rockstar 400 has relatively low carbon equivalent for superior weldability and is supplied in quenched and tempered condition. The specially designed tempering cycle renders formability with minimal effect on hardness. Rockstar 400 is suitable for yellow goods application in mining and construction markets such as crushers, body liners for truck beds, buckets, hoppers, chutes, excavators and conveyor troughs. Concrete mixer drums, trash truck bottoms, bucket lips, street sweepers and dump trailers are among other applications.
