ARMORING PART FOR A VEHICLE

Abstract

An armoring part for a vehicle includes a steel plate made of at least partially hot formed and press hardened armor steel and having a hardness of 380 to 760 Vickers (HV). Applied on at least one side of the steel plate is a coat which is made of a metal material which is softer than a metal material of the armor steel. The coat is a thermally applied layer and has a hardness of 10 to 230 Vickers (HV).

Claims
