T440HBW hardened high toughness penetration and shock resistance ballistic plate for blast protection
Blast protection plate.
T440HBW ballistic steel combines excellent penetration and shock resistance.
It offers vehicle designers new ways to increase protection using lighter weight designs.
Benefits of using T440HBW ballistic steel include:
• Superior workshop properties
• Optimized solutions
• Perfect hardness/toughness balance, for combined penetration and blast protection
• Expertise in ballistic protection from VANFORGE
T440HBW ballistic steel is not intended for further heat treatment.
T440HBW ballistic steel is available in thicknesses between 4.0 and 80.0 mm.

(1) Average of three tests. Transverse to rolling direction. Single value min. 70 % of specified average.
(2) For plate thicknesses under 12 mm sub-size Charpy-V specimen are used. The specified minimum value is then proportional to the specimen cross-section.
Brinell hardness test according to EN ISO 6506-1 on each heat treatment individual.
Charpy impact test according to EN ISO 148 on each heat and thicknesses from 6 mm.
Tensile test according to EN ISO 6892 on each heat and thicknesses.
According to EN ISO 10 160 Class E3S3.

Fabrication and Other Recommendations
Welding, bending and machining
T440HBW ballistic steel is not intended for further heat treatment. If T440HBW steel is heated above 170 °C after delivery from VANFORGE no guarantees for the properties of the steel are given.
Nitriding or surface coating may be carried out if the temperature is below 170 °C.
Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on the product. Grinding, especially of primer coated plates, may produce dust with high particle concentration.
