Abstract

Disclosed is a high-strength high-toughness and wear-resistant composite steel plate, comprising a substrate layer and a composite layer of which a single side or double sides are composited on the substrate layer. The substrate layer is a carbon steel layer and the composite layer is a ultra-high manganese steel layer with a content of Mn element in the composite layer being about 16.00-25.00 wt. %. Further disclosed is a manufacturing method for making the high-strength high-toughness and wear-resistant composite steel plate. With high strength and hardness, high wear resistance and high toughness, the high-strength high-toughness and wear-resistant composite steel plate has excellent comprehensive performance.
