Plate Armor

Plate armor is formed from specially-hardened steel and is used to provide protective covering in a wide range of applications. Some common characteristics of plate armor include weldability, formability, ballistic protection and flatness.

Industry Information

Plate Armor

While plate armor is most often used in the military for combat and defense purposes, there are many non-military applications that include the protection of government officials, private citizens and even some energy and industrial facilities. Able to be configured for specific applications, plate armor can be used on individuals as body armor, particularly when it is light-weight, for both military and civilian use. However, it is more common for plate armor to be used as structural components such as gun shields, personal armored vehicles, guard booths, safe rooms, riot shields and military vehicle door panels. In order for plate armor to be utilized by the United States military, it must undergo ballistic testing. The Defense Federal Acquisition Regulation Supplement dictates certain conditions that armor plating and other equipment must meet before it is used by military personnel and members of other government branches and agencies.

There are several different hardening processes that steel plate undergoes in order to be fabricated into plate armor. Two common processes are quench hardening and tempering. Both methods of metal heat treating, quench hardening involves heating the steel to a critical temperature and then cooling heated steel at a sufficiently rapid rate so that it minimizes any damage to the internal microstructure as well as avoiding warpage and residual stresses. Typically performed subsequent to quench hardening, tempering is used to make the steel more suitable for usage, since the quenching can make the steel too hard and too brittle to meet the stringent regulations. Thus, in tempering the metal is reheated to a certain temperature, held for a specific amount of time, and then cooled using air. While this does decrease the hardness of the steel, it also reduces its brittleness. Other methods of metal hardening often performed on plate armor include high energy beam hardening, face hardening and case hardening. In addition, there is self-hardening steel that is intrinsically hard without having to undergo any type of additional heat treatment.
