Title (EN) WELDED METAL AND WELDED STRUCTURE CONTAINING SAID WELDED METAL
(FR) MÉTAL SOUDÉ ET STRUCTURE SOUDÉE CONTENANT LEDIT MÉTAL SOUDÉ
(JA) 溶接金属、および該溶接金属を含む溶接構造体
Abstract:
(EN) A welded metal which satisfies a predetermined component composition, and wherein if N (particles/mm2) is the number of carbide particles present in the welded metal and having a circle-equivalent diameter of 0.1 μm or more and n (particles/mm2) is the number of carbide particles present in the welded metal and having a circle-equivalent diameter of 0.1-0.4 μm, N is 1.2 × 106 (particles/mm2) or more and N and n satisfy formula (1). n/N > 0.8 (1)
(FR) L'invention concerne un métal soudé qui satisfait une composition de constituant prédéfinie. Si N (particules/mm2) est le nombre de particules de carbure présentes dans le métal soudé et ayant un diamètre équivalent au cercle de 0,1 μm ou plus et n (particules/mm2) est le nombre de particules de carbure présentes dans le métal soudé et ayant un diamètre équivalent au cercle de 0,1-0,4 μm, N est égal à 1,2 × 106 (particules/mm2) ou plus et N et n satisfont la formule (1). n/N > 0,8 (1)
(JA) 所定の成分組成を満足する溶接金属であり、該溶接金属中に存在する円相当直径が0.1μm以上の炭化物粒子数をN(個/mm)、円相当直径が0.1~0.4μmの炭化物粒子数がn(個/mm)としたとき、前記Nは、1.2×10(個/mm)以上であり、前記Nと前記nは、下記式(1)を満足する溶接金属。 n/N>0.8 ・・・(1)
