TruSHIELD 500 Plate

Product and Application

TruSHIELD 500 armor plate, formerly Aegis Shield 500, provides excellent ballistic performance and an outstanding weight-to-ballistic-protection ratio. This quenched and tempered product excels in downstream fabrication processes like bending, laser cutting and plasma cutting. This product is used widely in the commercial vehicle armoring, explosion protection, military equipment and commercial body armor applications.

Available in thicknesses up to 0.500”, widths up to 60” and lengths up to 288”.

Fabrication, Bending, Post-Delivery Heating and Welding

Bending	Free bending should be performed utilizing maximum allowable bend radius to prevent cracking. TruSHIELD 500 plates 0.250” (6.35 mm) thick and less can be bent using a transverse radius of 4T and a longitudinal radius of 3.5T. Larger bend radius is recommended for thicker plates. Transverse radius is the bend line parallel to rolling direction.
Post-Delivery Heating	TruSHIELD 500 armor plate achieves its properties through quenching and tempering processes. Heating in fabrication (such as post-weld stress relieving) or in service must not exceed 400° F without risk of lowering the strength and hardness of the material.
Welding	TruSHIELD 500 armor plates can be welded by conventional processes such as SMAW, SAW and GMAW, provided that the weld procedures used are suitable for this grade and design of the welded structure, using low hydrogen conditions.

*These statements are general guidelines. CMC Impact Metals is not responsible for the results of any welding work performed.
