Frequently Asked Questions

  • What is armor plate steel?


    Armor plate steel is an abrasion resistant steel plate that is manufactured to perform under military conditions. Armor plates have high hardness and their thickness and other mechanical and physical properties vary according to the application. Typical applications include armored vehicles, body armor, battle tanks, and many other armored military uses.

  • What type of steel is used in body armor?


    AR500 is a very common steel armor plate that is used in body armor. It is a specific kind of abrasion resistant steel with a high surface hardness, also called Brinell Hardness, of 477-534. This hardness gives the armor steels the ability to resist wear, including from high impact, but it also reduces its malleability.

  • How are armor plate used?

    Armor plates are rigid plates made from abrasion resistant steel plates that are designed to provide protection against various types of threats, such as bullets, shrapnel, or explosives. They are commonly used in personal protective equipment (PPE) and armored vehicles to enhance the safety and survivability of individuals in high-risk environments, including military operations, law enforcement activities, and civilian security.

    Armor plates can be made from different materials, depending on the level of protection required and the specific application. The most common material is steel plate because of its durability and historical use in armor applications. They provide good protection against ballistic threats.

    Armor plates are typically designed to be inserted into carriers or vests, such as plate carriers or bulletproof vests. These carriers hold the plates securely against the wearer’s body, ensuring proper coverage and minimizing movement during use.

    It’s important to note that the effectiveness of armor plates can vary based on factors such as the thickness and quality of the plate, the specific threat being faced, and the velocity and caliber of projectiles. Different standards and ratings, such as NIJ (National Institute of Justice) standards, are used to assess and certify the performance of armor plates in specific scenarios.
