The relationship between magnetic aging and texture of 50W800 non‐oriented silicon steel (0.002~0.003 % C) was investigated. The Young's modulus of cementite is very close to that of {100} planes in ferrite and obviously lower than those of other crystallographic planes in ferrite. Therefore, cementite particles would precipitate in the form of disks along the {100} planes of the ferrite matrix during aging. The magnetic properties after aging at 200°C for 24 hours showed that the aging precipitation of cementite particles increased the core loss. The driving force for the wall movement of 180° stripe domains depends on the sheet texture. The texture, in which the <100> direction is parallel to the magnetizing field, is the most favourable texture component to reduce the core loss increment induced by aging.
