Feasibility study on developing high-nitrogen steels by refining in suspended state under high pressure

  • L. Zhekova
  • Ts. Rashev


High-nitrogen steels are finding increasing use in the industrially developed nations. However, they are still not being used to their full potential. Among the reasons are the time and money needed to develop new grades of high-nitrogen steels. This article reports on the progress made in this area by the Institute of Metallurgy of the Bulgarian Academy of Sciences. As an example, it describes the quick and efficient process followed in developing a new nickel-free low-manganese austenitic stainless steel obtained by refining in the suspended state under pressure.
