Bulletproof steel plates are generally used in bulletproof and explosion-proof projects, such as bulletproof doors, bulletproof helmets, bulletproof vests, and bulletproof shields; Bank counter, confidential safe; Anti riot vehicles, bulletproof cash carrying vehicles, armored personnel carriers, combat vehicles, submarines, landing boats, anti smuggling boats, helicopters, etc. Introduction to bulletproof steel plate of Shanghai Qiaoxiao Protective Materials Co., Ltd.:
Armored bulletproof steel imported from Sweden: PRO500. [1]
Bulletproof steel plate Four features of PRO500 armor plate:
1. Careful design of alloy composition: low alloy microalloying enables the performance to be maximized and has the best process performance.
2. Refined raw materials: repeated refining inside and outside the furnace; The harmful gases and impurities are stirred to the minimum; It can be welded and cold bent.
3. Precision hot-rolled plate type: minimum thickness tolerance; Maximum two-way flatness.
4. Automatic spray quenching: fine microstructure and uniform hardness distribution.

Manufacturing process of PRO500 armored bulletproof steel plate: [1]
1. Welding performance: the carbon equivalent of PRO500 steel is between 0.50-0.62, indicating that this steel has good welding performance. The heat input during welding is about 1.5-2.5KJ/mm. Using domestic welding materials can also obtain high-quality welding workpiece.
2. Cold bending: follow the following points to avoid cracks during cold bending, please call our company for consultation.
3. Relation between bending inner radius and steel plate thickness: steel plate thickness mm: ＜ 6. Bending angle ＜ 90 °, indenter radius R/steel plate thickness t, R/t: 4.0, fulcrum spacing w/steel plate thickness t, W/t: 10.0
Thickness of steel plate mm: ≥ 6 ＜ 20. Bending angle ＜ 90 °, indenter radius R/steel plate thickness t, R/t: 8.0, fulcrum spacing w/steel plate thickness t, W/t: 12.0
