BULLET-PROOF STEEL PLATE BY WELDING

摘要

The multi-layered buildup welding steel plate has good bulletproof property by retarding the advance of bullets and reducing the formation of cracks. The welding plates consist of the first buildup welding layer group having one or more than welding layer including one buildup welding layer of iron alloy with high hardness, and the second buildup welding layer group having one or more than welding layer including one buildup welding layer of iron alloy with high ductility. The welding plate is useful for armored structural material
