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. It has high hardness and its 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 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 steel the ability to resist wear, including from high impact, but it also reduces its malleability.
