T500HBW QT high toughness and yield ballistic steel plate
Description
High hardness armor with extraordinary toughness properties.
T500HBW ballistic steel is the world’s toughest protection plate, having nominal 500 HBW hardness, for use in vehicles, buildings and many more applications.
Benefits of T500HBW include:
• Market-leading steel protection
• Superior workshop properties
• Optimized solutions
• Perfect hardness/toughness balance, for combined penetration and blast protection
• Expertise in ballistic protection from VANFORGE
It offers vehicle designers new ways to increase protection using lighter weight designs.
T500HBW steel is not intended for further heat treatment.
Dimension range
T500HBW is available in thicknesses between 3.0 and 80.0 mm. Other dimensions to be agreed with VANFORGE.
Mechanical Properties
| Thickness (mm) | Hardness (HBW) | Charpy-V(1), 10x10 mm test specimen(2) Min. | Yield Strength Rp0.2 (min MPa) | Tensile Strength Rm (MPa) | Elongation A5 (min %) | Elongation A50 (min %) |
| 3.0 - 80.0 | 480 - 540 | 32 J / -400C | 1250 | 1450- 1750 | 8 | 10 |
(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.
Mechanical Testing
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 4 mm.
Tensile test according to EN ISO 6892 on each heat and thicknesses under 19.9 mm.
Ultrasonic testing
According to EN ISO 10 160 Class E3S3.

Delivery Conditions
The delivery condition is QT (Quenched and Tempered).
Fabrication and Other Recommendations
Welding, bending and machining
T500HBW ballistic steel is not intended for further heat treatment. If T500HBW steel is heated above 190 °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 190 °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.
