Title (EN) CORROSION AND CRACKING RESISTANT HIGH MANGANESE AUSTENITIC STEELS CONTAINING PASSIVATING ELEMENTS
(FR) ACIERS AUSTÉNITIQUES À HAUTE TENEUR EN MANGANÈSE, RÉSISTANT À LA CORROSION ET À LA CRAQUELURE ET CONTENANT DES ÉLÉMENTS DE PASSIVATION
Abstract: front page image
(EN)Improved steel compositions and methods of making the same are provided. The present disclosure provides advantageous corrosion and/or cracking resistant steel. More particularly, the present disclosure provides high manganese (Mn) steel compositions having enhanced corrosion and/or cracking resistance, and methods for fabricating high manganese steel compositions having enhanced corrosion and/or cracking resistance. Methods for fabricating high manganese steel compositions (e.g., via passivation) having enhanced corrosion and/or cracking resistance are also provided.
(FR)La présente invention a pour objet des compositions d'acier améliorées et leurs procédés de fabrication. La présente invention concerne un acier avantageux résistant à la corrosion et/ou à la craquelure. La présente invention concerne plus précisément des compositions d'acier à haute teneur en manganèse (Mn) ayant une résistance à la corrosion et/ou à la craquelure améliorée, ainsi que des procédés de fabrication desdites compositions. La présente invention concerne également des procédés de fabrication desdites compositions, par exemple par passivation.
