Rockstar 400 Plates
Overview
Rockstar 400 Plates are high-hardness, low-alloyed martensitic steels, known for their exceptional abrasion resistance. These plates achieve their hardness through an intense water quenching and tempering process. Available in three nominal hardness levels—400, 450, and 500 BHN—Rockstar plates are designed to provide a blend of high hardness, toughness, and good formability.
