Abstract

Otelul aliat Cr-Ni-Mo-Mn-Cu conform inventiei se caracterizeaza prin aceea ca în scopul cresterii plasticitatii la forjare sau laminare la cald si al coborarii sensibilitatii fragilizare contine 0,15....0,18% azot 0,02....0,05% aluminiu si sub 0,005% sulf.The Cr-Ni-Mo-Mn-Cu alloy steel according to the invention is characterized in that in order to increase the plasticity for forging or hot rolling and lowering the fragility sensitivity it contains 0.15 to 0.18% nitrogen 0.02. ... 0.05% aluminum and less than 0.005% sulfur.
