The authors investigated the mechanical and corrosion properties of high-chromium steel (25 wt.% Cr) particularly free of deleterious impurities (C + N < 0.02 wt.%), the so-called superferrites, additionally alloyed with 1-4% Ti or 1-2% Mo. The article shows that in principle it is possible and advantageous to alloy superferrites with titanium (1-2%). It was established that Ti and Mo reduce the corrosion rate of steel in solutions of H/sub 2/SO/sub 4/ and HCl in a broad temperature range. Steel alloyed with Mo (1-2%) or Ti (1-2%) is less prone to pitting in solution of FeCl/sub 3/ than steel 01Kh25TB (the initial unalloyed one) and a number of other industrial steels. An addition of 1% Ti greatly improves the technological properties of steel 01Kh25.
