In this study the hardenability, the cooling rates and microstructures of low alloy Cr-Mo and Mn-Mo steels were investigated. The cooling rate determines of amount of martensite structure. Hardenability test was carried out by Jominy method. Microstr

Izvršena je korekcija postojećeg kemijskog sastava čelika. Smanjen je sadržaj ugljika i vanadija, a povećan sadržaj mangana, osim toga dodan je niobij uz povećan sadržaj dušika i aluminija. Pozitivni rezultati istraživanja ostvareni su žar
