300HBW High Mechanical Quenched And Tempered Steel Plate Smooth Surface

300HBW hardening high strength low alloy steel ballistic steel plate

General Product Description

The low-alloy protection plate.

300HBW ballistic steel is a low-alloy protection plate, available as sheet in thicknesses of 3‑6 mm (0.118‑0.236″) and delivering a hardness of 260‑320HBW.

300HBW ballistic steel is not intended for further heat treatment.

Dimension Range

300HBW ballistic steel is available as cut-to-length sheet in thickness between 3.0-6.0 mm.
