The properties of high-nitrogen steels are briefly reviewed, along with their production technologies. High-nitrogen steels are preferable to traditional steels in many respects: specifically, their yield point is four times higher, with a distinctive combination of other properties; expensive alloying elements such as Ni, Mo, Co, and W are required in smaller quantities, if at all; and effective...
The development of iron and steel production is briefly reviewed. Metallurgy under gas pressure appeared at the end of the twentieth century. Even at this early stage, some significant benefits of metallurgy under pressure over traditional metallurgy and vacuum metallurgy have been established, such as fourfold increase in yield point with reduced consumption or elimination of some expensive alloying...
