High protection HBW 500 steel - Quardian 500
High protection HBW 500 steel is a protection plate steel that combines excellent properties in ballistic resistance with high strength and an average hardness of 500 HBW.
High protection HBW 500 steel (Quardian 500) is used in the applications such as armoured limousines, hbw 500 steel patrol vehicles, hbw 500 steel shooting stands, valuable transporters, and protected buildings. Thismaterial complies with NFA 36-800-THD2, MIL DTL 46100E,EN 1522, VPAM PM 2007.
High protection HBW 500 is supplied in the following range:
• Thickness: 3.6 - 40 mm
• Width: 1500 - 3100 mm
NLMK Clabecq carries on the extension of its dimensional program of Quardian 500 in order to propose quickly athickness range from 3.2 to 50 mm.
High protection HBW 500is delivered as quenched and tempered
Note:Brinell hardness test, HBW according to EN ISO 6506-1, is performed 1 - 2 mm below the plate surface once per heat treatment individual
