FIELD: metallurgy.SUBSTANCE: invention relates to a flux-cored wire. Flux-cored wire comprises a steel sheath and a powdery blend, comprises components in following ratio, wt%: fluorspar 1.0-2.0; ferrochrome 20.0-24.0; ferromolybdenum 0.5-2.0; boron carbide 4.0-12.0; iron powder 0-16.5; steel shell - balance. Ferro-materials and pure metal powders are used for production of flux-cored wire. Composition of charge varies depending on deposition method including coefficients of transition of alloying elements in weld metal.EFFECT: higher wear resistance of weld metal, operating at abrasion in contact with corrosive medium.1 cl, 2 tbl |
