Title (EN) FERRITIC STAINLESS STEEL SHEET
(FR) TÔLE D’ACIER INOXYDABLE FERRITIQUE
(JA) フェライト系ステンレス鋼板
Abstract: front page image
(EN)The purpose of the present invention is to provide a ferritic stainless steel sheet with excellent weld shape and excellent corrosion resistance of dissimilar metal welds with austenitic stainless steel. Provided is a ferritic stainless steel sheet containing, in mass%, C: 0.003-0.020%, Si: 0.01-1.00%, Mn: 0.01-0.50%, P: 0.040% or less, S: 0.010% or less, Cr: 20.0-24.0%, Cu: 0.20-0.80%, Ni: 0.01-0.60%, Al: 0.01-0.08%, N: 0.003-0.020%, Nb: 0.40-0.80%, Ti: 0.01-0.10%, Zr: 0.01-0.10%, the balance being made of Fe and unavoidable impurities, and the components satisfying expression (1). 3.0≥Nb/(2Ti+Zr+0.5Si+5Al)≥1.5 --- (1). The element symbols in expression (1) represent the contents (mass%) of said elements.
(FR)Le but de la présente invention concerne une tôle d'acier inoxydable ferritique ayant présentant une excellente forme de soudure et une excellente résistance à la corrosion de soudures métalliques dissemblables avec de l'acier inoxydable austénitique. L'invention concerne une tôle d'acier inoxydable ferritique contenant, en % en masse, C : 0,003-0,020 %, Si : 0,01-1,00 %, Mn: 0,01-0,50 %, P : 0,040 % ou moins, S : 0,010 % ou moins, Cr : 20,0-24,0 %, Cu : 0,20-0,80 %, Ni : 0,01-0,60 %, Al : 0,01-0,08 %, N : 0,003-0,020 %, Nb : 0,40-0,80 %, Ti : 0,01-0,10 %, Zr : 0,01-0,10 %, le reste étant constitué de Fe et d'impuretés inévitables et les constituants satisfaisant à l'expression (1). 3,0 ≥ Nb/(2Ti+Zr+0,5Si+5Al) ≥ 1,5 --- (1). Les symboles des éléments dans l'expression (1) représentent les teneurs (% en masse) desdits éléments.
(JA)溶接部形状に優れ、かつオーステナイト系ステンレス鋼との異材溶接部の耐食性に優れるフェライト系ステンレス鋼板を提供する。 質量%で、C:0.003~0.020%、Si:0.01~1.00%、Mn:0.01~0.50%、P:0.040%以下、S:0.010%以下、Cr:20.0~24.0%、Cu:0.20~0.80%、Ni:0.01~0.60%、Al:0.01~0.08%、N:0.003~0.020%、Nb:0.40~0.80%、Ti:0.01~0.10%、Zr:0.01~0.10%、を含有し、残部がFeおよび不可避的不純物からなり、下記式(1)を満足する、フェライト系ステンレス鋼板。3.0≧Nb/(2Ti+Zr+0.5Si+5Al)≧1.5・・・(1)。なお、式(1)における元素記号は、その元素の含有量(質量%)をあらわす。
