Fabrication and Other Recommendations

Welding, bending and machining

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