The military advantages of AR500 armor steel plate

The dynamic rolling process of AR500 armor steel plates results in a smoother hardness gradient along its thickness, maintaining uniform ballistic performance even in 76.2 mm thick plates. In contrast, traditional armor is prone to stress concentration in welded areas.

AR500 steel's grain orientation optimization technology reduces the probability of crack initiation. Its high-manganese alloy-reinforced grain boundary structure forms a dense martensitic microstructure, achieving a hardness of HBW500. The microscopic network of carbides effectively disperses impact energy, extending fatigue life by more than three times.
