Abstract

Tests on type 09G2S steels in the heat treated condition showed that experimental melts treated with rare earth metals during smelting are much stronger and tougher at subzero temperatures (without being less ductile) than ordinary steels of this kind. The addition of rare earth metals (cerium) produces a substantial change in the nature of nonmetallic inclusions (collectors) and eliminates the segregation of sulfur which has a beneficial effect on the plasticity and certain other properties of steel. One of the possible ways of improving type 09G2S steels is by modifying their composition with trace additions of cerium and boron.
