Abstract
1. Crystallization of corrosion-resistant 18-8 type steels with additions of titanium ceases with eutectic transformation. First from the liquid there is separation of titanium carbosulfide eutectic, and then at a lower temperature titanium carbide eutectic forms. 2. In 18-8 type steels even with a small carbon and sulfur content a considerable amount of eutectic forms as a result of dendrite liquation of sulfur and carbon. In ingots and castings during cooling after solidification carbides and carbosulfides hardly separate from austenite. These inclusions may only precipitate after high-temperature heating of the steel (to 1200–1340°C), with which a considerable amount of eutectic titanium carbides and carbosulfides dissolves in austenite. 3. In industrial 18-8 type steels complex sulfides (Mn, Ti) and (Fe, Ti) are not observed.
