Super Bainite Armour Steel

A readily machinable ultra-high hardness steel designed for armour plating

Appliqué armour for fighting vehicles is both expensive and adds weight to the platform. Super Bainite Steel is a low cost ultra-high hardness steel that provides an alternative to current protective armour plate. During live fire trials it has demonstrated performance matching that of current high hardness armour steels and some ceramic armours.


  • Ballistics performance meets the same European and NATO standards as Armox® 600 and MARS® 300
  • Half the weight for the same level of protection compared with Rolled Homogeneous Armour (RHA)
  • Low cost alternative due to its low chrome and nickel composition
  • Readily machinable in pearlite state or final form using conventional tooling
  • Simple manufacturing process
