Material Properties of Bulletproof Steel Plate
Bulletproof steel plate as a high-performance safety protection material, mainly has the following characteristics:
High strength and high toughness: Through the scientific alloy ratio and heat treatment process, the steel has excellent toughness while maintaining high hardness. It can withstand high strength impact and penetration.
Excellent elastic resistance: This type of steel plate is specially designed to defend against high-speed flying objects such as bullets. Its anti-elastic ability can reach a higher level of protection. For example, the protective capability of NP550 bulletproof steel plate has reached the level of C-level protection armored vehicles.
Good energy absorption and impact resistance: This steel plate can not only effectively resist direct impact, but also has good energy absorption capacity. It reduces the impact damage to the target.
Production Process of Bulletproof Steel Plate
Raw material selection and pretreatment:
The raw materials are usually alloy steel with high strength and high toughness, such as low-carbon alloy steel, stainless steel or special alloys. These materials have good impact resistance and processability.
Before the raw materials are put into production, they need to undergo strict chemical composition analysis and physical property testing to ensure that the quality meets the standards.
Smelting and casting:
High temperature smelting in an electric furnace or converter with precise control of melting temperature and time. This ensures that the alloying elements are evenly distributed.
Through continuous casting or die casting process, molten steel is cast into billets suitable for subsequent processing.
Hot and cold rolling:
In the hot rolling stage, the billet is heated above the recrystallization temperature for rolling. This can improve the plasticity and toughness of the material.
Then cold rolling is carried out to refine the grain and improve the strength and hardness of the steel plate through multi-pass rolling. At the same time, ensure that the plate shape is straight.
Heat treatment:
Quenching and tempering are the key steps in the manufacture of bulletproof steel plates. Quenching makes the steel plate obtain high hardness by rapid cooling, while tempering eliminates quenching stress by proper heating and insulation. This can improve the toughness and comprehensive mechanical properties of the material.
Surface treatment:
Bulletproof steel plate often needs surface treatment such as shot peening and rolling strengthening to improve its elastic resistance and surface quality.
For some high-end applications, workers will also perform coating treatment, such as galvanized, aluminum plating and so on. This enhances anti-corrosion properties.
