Dynamic Armor 46100

Dynamic Armor 46100® is a high hardness ballistic steel plate specifically designed for lightweight armor applications that require maximum resistance to ballistic threats. As a specialty plate, it is available in thicknesses from 3/16” through 2” (4.7mm through 50mm). Dynamic Armor 46100® plate exhibits a superior combination of ballistic resistance, hardness, formability, weldability, toughness and flatness. It is produced using an optimum combination of carbon and alloy content, to offer a maximum resistance to ballistic penetration.

Ballistic Resistance

Dynamic Armor 46100® plate is designed to exceed the ballistic requirements set forth in the MIL-DTL-46100E specification; this includes previous revisions to the specification.

Hardness

Dynamic Armor 46100® plate has a Brinell hardness range of 477-534 and a nominal hardness of 500 BHN.

Production Size Capability

  • Dynamic Armor 46100® plate is produced in thicknesses from 3/16” (4.7mm) through 2” (50.8mm) and in widths from 72” through 120”.
  • Thicknesses of 5/16” and less have a maximum width of 96”.
  • Standard thicknesses include: 3/16”, ¼”, 5/16”, 3/8” ½”, 5/8”, ¾”, 1”, 1-1/4”, 1-1/2”, 1-3/4” and 2”.
  • Maximum length is 600”.
  • Standard pattern widths and lengths are 96” x 288”, 96” x 240” and 96” x 480”.
  • Metric and other sizes are available on inquiry (* – inquire on 3/16”, ¼” and 5/16” sizes for availability).

Thermal Cutting

Dynamic Armor 46100® plate can be thermally cut using conventional methods of laser, plasma, and oxy-fuel cutting techniques provided that the minimum plate temperature is +60°F prior to cutting.

Cold Forming

Following good shop forming practices and uniform load application, Dynamic Armor 46100® plate can be formed to a minimum radius of 4*t against a bend line transverse to the rolling direction and a radius of 6*t against a bend line that is parallel to the rolling direction, for thicknesses ≤5/16”. For thicknesses >5/16”, Dynamic Armor 46100® plate can be formed to a minimum radius of 6*t against a bend line transverse to the rolling direction and a radius of 8*t against a bend line that is parallel to the rolling direction.

Good shop practices include a minimum plate temperature of +60°F, grinding plate edges, conditioning and lubricating form dies and applying uniform bending force. The recommended minimum bottom die opening should be at least 16 times the plate thickness. Because of the enhanced mechanical properties of this plate, the bending forces required to form the plate will be greater and more plate “springback” can be expected to occur.

Welding

Dynamic Armor 46100®  plate can be welded using conventional welding practices such as SMAW, GMAW and SAW provided low hydrogen filler metal and welding practices are employed. Interpass temperatures should not exceed 400°F and post-weld heat treatment is not recommended if the original hardness levels are to be maintained.

Applications

Dynamic Armor 46100® plate is used in a variety of lightweight armor applications where maximum protection and resistance to ballistic threats is critical, such as armored personnel carriers, tanks, tactical combat vehicles, armored municipal & government vehicles, personal armored cars, armored cabs, etc.
