Mars® 500: High hardness Armor

Mars® 500 is a high-hardness (typical 500 HBW) protection steel offering the optimal combination of ballistic resistance and workability for the following applications:
– Very light to medium-weight vehicles structures
– Add-on armour of any thickness for usage up to heavy tanks.
– Boxes, containers, shelters, reservoirs, door frames, etc.


INDUSTEEL: Mars® 500
Mars® 500 can be ordered according to one of the following standards:

• France : NF A 36-800 THD 2
• USA : MIL-DTL-46100

Chemical composition – Ladle analysis – MAX Weight%

C S P Si Mn Ni Cr Mo B
≤ .31 ≤ .002 ≤ .010 ≤ .5 ≤ 1 ≤ 1.8 ≤ 1.6 ≤ .6 ≤ .003

Chemical composition depends on thickness range (particularly on Ni and Cr contents) and, possibly, on customer’s specification
