A cast steel with excellent workability, characterized in that not less than 60% of the total cross section thereof is occupied by equiaxed crystals, the diameters (mm) of which satisfy the following formula: D < 1.2 ×1/3 + 0.75, wherein D designates each diameter (mm) of equiaxed crystals in terms of internal structure in which the crystal orientations are identical, and × the distance (mm) from the surface of the cast steel. The cast steel and the steel material obtained by processing the cast steel have very few surface flaws and internal. defects.
L'invention concerne une pièce en acier moulé présentant d'excellentes aptitudes au formage, se caractérisant en ce que 60 % ou plus de la section transversale est constituée de grains équiaxiaux, selon la formule D < 1,2 <X1/3 >+ 0,75, dans laquelle D représente un diamètre (mm) d'un grain équiaxial dont la structure présente la même orientation que le cristal et X représente la distance par rapport à la surface (mm) de la pièce d'acier moulé. La pièce en acier moulé et le produit en acier produit par le formage de la pièce en acier moulé présentent une surface extrêmement réduite et d'infimes défauts internes.
