Abstract
Nonmetallic inclusions in the cast and rolled samples of austenitic stainless steel C0.03-Cr18-Ni10 and C0.08-Cr18-Ni10-Ti1 were studied by scanning electron microscopy. In steel alloyed with titanium, titanium nitrides and oxides of different dispersion were found around globular nonmetallic inclusions with separation of second phase. The inclusions in titanium-free steel have predominantly globular shape and represent oxide inclusions of complex composition. In C0.03-Cr18-Ni10 steel there is no big clusters of nonmetallic inclusions; that leads to high quality of cold-rolled sheet surface. On a surface of a cold-rolled sheet of C0.08-Cr18-Ni10-Ti1 steel there are defects as delaminations from the surface of the sheet, containing titanium nitride and slag-forming mixture.
