Particles of impurities, such as mould material, ferrous metal, or slag in the casting. Usually non-metallic particles contained in metal. In steel they may consist of simple or complex oxides, sulphides, silicates and sometimes nitrides of iron, manganese, silicon, aluminium and other elements. In general they are detrimental to mechanical properties but much depends on the number, their size, shape and distribution.
