摘要：

Reliability and durability of pipeline valves are largely determined by the resistance of weld sealing surfaces of its shut-off valve, which in its turn depends on the weld metal properties. To improve the durability of valves a new composition of a high chromium flux-cored wire with a boride compounds complex (BN, TiB2, ZrB2) producing weld composite metal is developed. It is stated that the formation of the martensitic matrix with a reduced structural fragments average size due to appearance of dispersed boride-nitride phases in this metal has resulted in high coating hardness and wear resistance.
