Research group headed by Dr. Ra Ju Hyon, head of Faculty of Metal Engineering, succeeded in the production of stainless steel on domestic natural resources, thus greatly contributed to the realization of the production of stainless steel Juche-orientated.
Dr. Ra Ju Hyon carried out further research on the production of ferrous-alloys from Nickel and Chrome, which are essential for making all alloys but rare in our country and at last succeeded in the production of ferrous-alloys from domestic resources.
The research group applied new scientific and technological method to produce ferro-nickel and ferro-chrome from domestic raw materials. They made stainless steel melting trial and successfully produced stainless steel of good standard.
Succeeding in the trial production, a real possibility to produce enough stainless steel urgently needed in several fields of the national economy was obtained.
