WIPO Patent Application WO/2021/002259
Kind Code:
A1
Abstract:
Provided are: an austenitic stainless steel flux cored wire from which a welded metal having excellent cryogenic temperature toughness can be produced; a welded metal having excellent cryogenic temperature toughness; and a welding method. An austenitic stainless steel flux cored wire in which a flux is filled in a steel-made shell, wherein the flux cored wire contains Si, Mn, Ni, Cr, C, P and N in amounts each falling within a specified range relative to the entire mass of the wire, with the remainder made up by Fe and unavoidable impurities, and X1 which is calculated in accordance with formula (1) is 17.5 to 22.0 inclusive. (1) X1 = [Ni]W+0.5×[Cr]W+1.6×[Mn]W+0.5×[Si]W+15×[C]W
In formula (1), [Ni]W, [Cr]W, [Mn]W, [Si]W and [C]W represent the contents (% by mass) of Ni, Cr, Mn, Si and C, respectively, relative to the entire mass of the wire.
