Abstract

Process for the treatment of a steel material, wherein the grains of which it is composed include a matrix into which precipitates are incorporated. The precipitates include at least one metallic element selected from a metallic element M, a metallic element M', a metallic element M″ or mixtures thereof. The microstructure of the steel is such that the grains are equiaxial and the average size of the grains being such that the average of their largest dimension 'Dmax' and/or the average of their smallest dimension “Dmin” is in the range 10 μm to 50 μm.
