Fabrication and Other Recommendations

Welding, bending and machining

550HBW ballistic steel is not intended for further heat treatment. If 550HBW 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.
