FIELD: metallurgy.
SUBSTANCE: invention relates to ferrous metallurgy and is to be utilised for manufacture of carbon and low-alloyed steels characterised by enhanced resistance to cold and various types of general and local corrosion. The modifier contains the following components (wt %): calcium - 12.0-20.0%, rare-earth metals - 25.0-39.0%, silica - 1.0-41.0%, magnesium - 0.5-3.0%, iron - balance with the rare-earth metals content complying with the condition REM=(1.5-2) (Ca+2xMg) where REM, Ca and Mg represent content of rare-earth metals, calcium and magnesium accordingly.
EFFECT: invention provides for enhancement of steel resistance to corrosion due to formation of modified non-metallic corrosively inactive inclusions without affecting its workability and physico-mechanical properties including strength and resistance to cold.
