Development and investigation of new special steel

  • 1 Institute of metal science, equipment and technologies „Akad. A. Balevski” with hydro and aerodynamics centre, Bulgarian Academy of Sciences, Sofia, Bulgaria


New special high nitrogen steel used in arms industry is developed. The new steel and technology of its production are developed on the basis of the metallurgy under pressure. The mechanical properties by the results of the short -term strength and notchimpact strength tests are determined. The new steel has higher mechanical characteristics in comparison with conventional nitrogen free analogue. Non-destructive control is carried out. Dense structure without defects is established.
