BISPLATE UHH 600
BISPLATE Armour UHH 600 steel is a quenched and tempered steel armour plate suitable for use in both military and civil applications where light weight and resistance to ballistic projectiles is required.
The chemical specification of BISPLATE Armour UHH 600 steel conforms to the requirements of MIL-DTL-32332, although somewhat tighter, so as to optimise the material’s performance.
Chemical analyses are taken on a per-heat basis.
BISPLATE Armour UHH 600 steel has a hardness range of 570 - 640 HBW with a nominal hardness of 600 HBW

Chemistry
The chemical specification conforms to the requirements of MIL-DTL-46100, although it is tighter than the requirements of that specification so as to optimise the material’s performance. Product chemical analyses are taken on a per-heat basis. Chemical analysis is as follows:
