What is EN 46100:


EN 46100 is a technical specification that defines the requirements for ballistic-resistant steel plates specifically designed for use in military vehicles and applications. This article aims to provide an in-depth understanding of EN 46100, including its composition, properties, testing methods, and applications. By the end of this article, you will have a comprehensive knowledge of EN 46100 and its significance in the field of military armor.

Composition and Properties

EN 46100 steel is primarily composed of iron, carbon, and various alloying elements such as manganese, chromium, and nickel. The precise composition may vary depending on the manufacturer, but it typically has a carbon content ranging from 0.15% to 0.25%. These alloying elements enhance the material's strength, hardness, and toughness, making it suitable for ballistic protection.

The properties of EN 46100 steel are determined through rigorous testing. It exhibits high hardness and tensile strength, enabling it to withstand severe impact and deformation without failure. Additionally, it possesses excellent resistance against penetration from small arms fire and shrapnel, providing effective protection to personnel and equipment inside military vehicles.

Testing and Certification

To ensure the quality and performance of EN 46100 steel, it undergoes various tests according to international standards. These tests include ballistic limit, detonation resistance, and fragment simulation projectile tests. The goal of these tests is to measure the steel's ability to resist penetration, minimize spallation, and maintain structural integrity under different ballistic threats.

Once the steel passes these tests, it can receive certification according to the specific level of protection it provides. Certification levels range from BR4 to BR7, with BR7 offering the highest level of ballistic resistance. This certification allows military organizations to accurately select and procure the appropriate EN 46100 steel for their specific needs.


EN 46100 steel finds widespread application in armored vehicles, providing crucial protection to military personnel during combat operations. It is used in the manufacturing of vehicle hulls, bulletproof windows, doors, and other vital components that require strong ballistic resistance.

In addition to military applications, EN 46100 steel is also utilized in civilian applications where high levels of ballistic protection are required. These include bank security systems, safe rooms, and body armor for law enforcement agencies.

Overall, the exceptional properties and performance of EN 46100 steel make it an indispensable material in the field of military armor and civilian ballistic protection solutions.
