This paper reports texture induced anisotropy of the carbon and nitrogen Snoek relaxation measured in a commercial carbon-manganese rolled steel. This phenomenon strongly influences determination of the concentration of C and N atoms dissolved in ferritic steel sheets. The relationship between the height of the Snoek peak and the concentration of foreign interstitial atoms (FIAs) in bcc single crystal is therefore reconsidered in the case of polycrystalline rolled steels. Anisotropy effect is observed in rolled steel sheets as well as in sheets subjected to various heat treatment. In all investigated cases the Snoek peak observed in samples cut at the angle of 45 degrees to the rolling direction (RD) is higher by around 45% than for perpendicularly or transversely cut specimens. Hence this effect is general. Strong anisotropy of the Snoek relaxation in rolled samples is explained by sensivity of the so-called Snoek orientation factor Gamma to texture components determined by the three-dimensional orientation distribution function ODF.
