600HBW quenched high hardness alloy steel ballistic plate
Description
The ballistic protection steel with extra-high hardness
600HBW ballistic steel is a ballistic protection steel of extra-high hardness, nominal 600 HBW, available in thicknesses of 3‑6 mm (0.118‑0.236″).
600HBW ballistic steel is available as cut-to-length sheet in thicknesses of 3‑6 mm (0.118‑0.236″). Delivered in quenched condition, 600HBW ballistic steel is not intended for further heat treatment.
Dimension Range
600HBW ballistic steel is available as cut-to-length sheet in thickness between 3.0 - 6.0 mm.
Mechanical Properties
| Thickness (mm) | Hardness (HBW) |
| 3.0 – 6.0 | 570 - 640 |
Mechanical Testing
Brinell hardness test according to EN ISO 6506-1 on each heat treatment individual/coil.
Hardness is measured on a milled surface 0.3 - 2 mm below plate surface.

Fabrication and Other Recommendations
Welding, bending and machining
600HBW ballistic steel is not intended for further heat treatment. If 600HBW ballistic steel is heated above 150 °C after delivery from VANFORGE no guarantees for the properties are given.
Appropriate health and safety precautions must be taken when cutting, welding, grinding or otherwise working on the product. Grinding, especially of primer coated plates, may produce dust with high particle concentration.
