Impact resistance of bulletproof steel plates
The impact resistance of a steel plate depends on its material, thickness, and workmanship. For example, a 10mm thick Q235 steel plate can withstand a direct hit from a 9mm pistol bullet (kinetic energy 500J)
Sep-12-2025
The core reason for the high price of bulletproof steel plates lies in the dual pressures of raw material costs and production processes. Taking NIJ Level III bulletproof steel plates as an example, they require high-strength alloy steel or ceramic compos
Sep-05-2025
The origins of bulletproof steel plates can be traced back to the rolled homogeneous armor of World War I tanks. During World War II, nickel-chromium alloy steels increased their protective effectiveness by 125% through carburizing and hardening. However,
