Title:
FLUX-CORED WIRE
Document Type and Number:
WIPO Patent Application WO/2022/050400
Kind Code:
A1
Abstract:
The present invention provides a flux-cored wire for stainless steel welding having good welding workability. This flux-cored wire for arc welding has a steel outer sheath filled with flux. Per total mass of wire the flux-cored wire contains Cr: 16.0-22.0 mass%, Ni: 6.0-11.0 mass%, Mn: 0.7-2.6 mass%, Si: 0.1-1.1 mass%, Zr: 0.2-0.8 mass%, Fe: 45.0-65.0 mass%, TiO2: 5.0-9.0 mass%, SiO2: 0.1-2.0 mass%, and ZrO2: 0.5-3.0 mass%, and is restricted to Bi: less than 0.0020 mass% (including 0 mass%). The value of parameter A, which is expressed by A=[Si]+2×[Zr], satisfies 1.4-2.5.
