Product Description

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 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.

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.
