[en] Effect of low additions of rare earth and refractory metals upon anticorrosion properties of iron-chromium steel Kh25T is studied. It is shown that titanium-containing Kh25T steel containing optimum amounts of cerium and niobium is quite perspective for its use in chemical industry as corrosion-resistant one. Cerium and niobium promote to size reduction and redistribution of excessive phases of titanium nitrides and titanium carbonitrides etc. Structural chan.oes caused by the effect of cerium and niobium, ensured increase of corrosion resistance of titanium-containing Kh25T steel by a factor of 2-3
