Abstract
It is an object to provide a stainless steel flux-cored wire in which the amount of hexavalent chromium in fume can be reduced while maintaining the weldability excellent. The stainless steel flux-cored wire contains, as percentage to the total mass of the wire: Cr: 11-30 mass %; metal Si, Si oxide and Si compound: 0.5-4.0 mass % in total in terms of Si [Si]; fluorine compound: 0.01-1.0 mass % in terms of F [F]; TiO: 1.5 mass % or above; ZrO+AlO: 3.2 mass % or below; Na compound, K compound and Li compound: 0.50 mass % or below in total of each of an amount in terms of Na [Na], an amount in terms of K [K] and an amount in terms of Li [Li]; and satisfies {([Na]+[K]+[Li])×[Cr]}/([Si]+4.7×[F])≤10, where [Cr] represents Cr content.
