450HBW Impact Toughness Protection Bulletproof Steel Plate Quenched And Tempered
Description
Combines ballistic properties with impact toughness.
450HBW ballistic steel is a medium-hard protection plate combining ballistic properties with impact toughness, at 8‑16 mm (0.315‑0.630″) thick and 400‑480 HBW.
450HBW ballistic steel is not intended for further heat treatment.
Dimension Range
450HBW ballistic steel is available as plate in thickness between 8.0 - 16.0 mm.
Mechanical Properties
| Thickness (mm) | Hardness Min - Max (HBW) | Yield Strength Min (min MPa) | Tensile Strength Min (MPa) | Elongation A5 Min (min %) |
| 8 - 16 | 400 - 480 | 1000 | 1150 | 8 |
Impact Properties
| Test temperature | Min. impact energy test Charpy-V 10x10 mm test specimens (1) |
| -40 °C | 20 J |
(1) Impact testing transverse to rolling direction, average value of three tests. Single value min. 70% of specified average.
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.
Charpy impact test according to EN ISO 148, 1 test/20 ton.
Tensile test according to EN ISO 6892 on each plate and thickness <19.9 mm.
Chemical Composition (ladle analysis), %, max
| C | Si | Mn | P | S | Cr | Ni | Mo | B |
| 0.25 | 0.70 | 1.50 | 0.015 | 0.010 | 1.0 | 2.0 | 0.7 | 0.005 |
The steel is grain-refined.
Phosphorous and sulphur are not intentionally alloying elements.

Fabrication and Other Recommendations
Welding, bending and machining
450HBW ballistic steel is not intended for further heat treatment. If 450HBW ballistic steel is heated above 180 °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.
