Abstract

　母材および溶接金属が、質量％で、Ｃ：０．３％以下、Ｓｉ：２％以下、Ｍｎ：０．０１～３．０％、Ｐ：０．０４％を超えて０．３％以下、Ｓ：０．０３％以下、Ｃｒ：１２～３０％、Ｎｉ：６～５５％、希土類元素：０．２％を超えて０．６％以下、ｓｏｌ．Ａｌ：０．００１～３％およびＮ：０．３％以下を含有し、残部がＦｅおよび不純物からなり、かつ「（Ｃｒ＋１．５×Ｓｉ＋２×Ｐ）／（Ｎｉ＋０．３１×Ｍｎ＋２２×Ｃ＋１４．２×Ｎ＋５×Ｐ）＜１．３８８」の式を満足するオーステナイト系ステンレス鋼溶接継手は、Ｐ含有量が高く、完全オーステナイト凝固するにも拘わらず、耐溶接凝固割れ性に優れている。このため、溶接施工が要求される用途に幅広く適用することができる。なお、上記の式中の元素記号は、その元素の質量％での含有量を表す。
