FIELD: flux-cored wires.
SUBSTANCE: invention relates to flux-cored wires for coating, and can be used to protect the surface of products operating under conditions of high-temperature gas corrosion during cyclic heating (thermal cycles). The flux-cored wire consists of a steel sheath and a core made of charge containing, wt.%: aluminum 15.0-20.0, chromium 2.0-6.0, titanium 0.5-1.5, yttrium 0.5 -3.0, iron is the base.
EFFECT: invention provides an increase in the resistance of products to gas corrosion due to the formation of stable oxide films, such as Al2O3, and other complex oxides, on their surface during high-temperature exposure.
