The invention discloses a wear-resistant surfacing flux-cored wire. The wear-resistant surfacing flux-cored wire consists of a flux core and a low-carbon steel-tape sheath coating the outer side of the flux core, wherein the flux core comprises the following components: Cr, C, Ti, Nb, Zr, B, W, Mo, Si, Mn, Mg, Cu, Ni, Sr, Sm, Sc, Y, Eu, and the balance of Fe and inevitable impurities. The wear-resistant surfacing flux-cored wire is reasonable in composition and high in bonding strength with base metal, a surfacing layer is favorable in toughness, hardness, creep resistance and wear resistance, and the service life of hardware is prolonged.
