Title (EN) MARTENSITIC STAINLESS STEEL STRENGTHENED BY COPPER-NUCLEATED NITRIDE PRECIPITATES
(FR) ACIER INOXYDABLE MARTENSITIQUE RENFORCÉ PAR DES PRÉCIPITÉS DE NITRURE NUCLÉÉS AU CUIVRE
Abstract: front page image
(EN)A martensitic stainless steel alloy is strengthened by copper-nucleated nitride precipitates. The alloy includes, in combination by weight percent, about 10.0 to about 12.5 Cr, about 2.0 to about 7.5 Ni, up to about 17.0 Co, about 0.6 to about 1.5 Mo, about 0.5 to about 2.3 Cu, up to about 0.6 Mn, up to about 0.4 Si, about 0.05 to about 0.15 V, up to about 0.10 N, up to about 0.035 C, up to about 0.01 W, and the balance Fe and incidental elements and impurities. The nitride precipitates may be enriched by one or more transition metals.
(FR)Un alliage d’acier inoxydable martensitique est renforcé par des précipités de nitrure nucléés au cuivre. L’alliage comprend, de manière combinée, en pourcentage pondéral, d’environ 10,0 à environ 12,5 Cr, d’environ 2,0 à environ 7,5 Ni, environ 17,0 Co au maximum, d’environ 0,6 à environ 1,5 Mo, d’environ 0,5 à environ 2,3 Cu, environ 0,6 Mn au maximum, environ 0,4 Si au maximum, d’environ 0,05 à environ 0,15 V, environ 0,10 N au maximum, environ 0.035 C au maximum, environ 0,01 W au maximum, le solde étant constitué de Fe, d’éléments contingents et d’impuretés. Les précipités de nitrure peuvent être enrichis par un ou plusieurs métaux de transition.
